Eaton TVS supercharger boosts new 2020 Ford Mustang Shelby GT500

Power management company Eaton today announced its TVS R2650 supercharger helps boost the hand-built and Ford Performance-tuned, 5.2-liter V8 engine that powers the all-new 2020 Shelby GT500, the pinnacle of Ford Mustang performance.

The Eaton TVS R2650 supercharger is the evolution of the popular Twin Vortices Series (TVS) platform, which features a patented rotor coating for improved efficiency. The high-twist, four-lobe rotor design is 15 percent larger than the TVS 2300 supercharger found on the previous Shelby GT500 and features several improvements to maximize efficiency and improve performance at higher speeds.

The Eaton TVS R2650 supercharger in the all-new Shelby GT500 provides up to 12 psi of boost, helping to produce 760 horsepower and 625 lb.-ft. of torque, both of which make it the most powerful street-legal Ford ever and the most power- and torque-dense supercharged production V8 engine in the world.

Several technical modifications help this supercharger deliver supercar-level power and torque, including a 170-degree helical twist of its rotors, which is 10 degrees greater than previous TVS rotors. Other upgrades include bearing plate pressure relief points that reduce trapped volume pressure and optimized sealing for better flow efficiency.

Proudly crafted in the United States, the 2020 Mustang Shelby GT500's engine is hand-built at the Ford Motor Company's Romeo Engine Plant in Romeo, Michigan, and its innovative TVS R2650 supercharger is assembled at Eaton's Vehicle facility in Athens, Georgia.

"We are proud to collaborate with Ford Performance to help it produce the most powerful Mustang and street-legal Ford ever," said Karl Sievertsen, chief technology officer, Eaton's Vehicle Group. "As the world leader in supercharger production, we are committed to innovation that helps our valued customers achieve the best possible performance out of their vehicles."

Eaton has produced more than 7.5 million superchargers globally for a variety of applications.

While Eaton's TVS technology has long provided boost to high-performance vehicles, the technology also is used for advanced combustion engines, providing exceptional transient response with precisely metered air flow at any engine operating condition, independent of exhaust gas enthalpy. This is critical for new engine concepts, where high levels of air are often required at operating points at which turbochargers are limited.

As part of Eaton's commitment to the quality of life and the environment, TVS technology continues to evolve to enable cleaner and more efficient engines. The positive-displacement TVS technology provides the required airflow conditions precisely and instantaneously and can also deliver an additional boost in power. TVS technology can be driven mechanically or electrically, providing flexibility for automakers as they look to a more electrified future. TVS technology also is used in hydrogen fuel cell applications, as this technology often requires high levels of pressurized air at certain operating points.

The flexibility of Eaton's TVS technology even goes beyond automotive applications, enhancing performance in the personal watercraft industry and providing accurate airflow in industrial applications.

Eaton is a power management company with 2018 sales of $21.6 billion. We provide energy-efficient solutions that help our customers effectively manage electrical, hydraulic and mechanical power more efficiently, safely and sustainably.

Creating safer conditions for electrical workers and protecting equipment through safety by design

Electrical workers and facility owners rely on technical professionals to take prudent and economical steps towards increasing worker safety and protecting facility equipment. "Safety by design" describes, what I believe to be, a comprehensive approach to incorporating practical and feasible electrical distribution system design solutions. The three pillars of success for electrical safety include:

          1. Eliminating hazards by establishing electrically safe working conditions.
          2. Implementing designs that reduce the likelihood of a hazardous occurrence.
          3. Reducing the potential severity of injuries should an accident occur when justified energized work is required.

When the industry is focused on these three pillars, the result is safer conditions for electrical workers and better protected equipment.

Safety by design – A three-part approach

Every electrical product and system must be designed with worker and equipment safety in mind. The following section explores in more detail the safety by design approach and its three components.

Part 1 - Eliminate the hazard

Hazard elimination is the act of establishing an electrically safe working condition. The NFPA 70E (National Fire Protection Association) committee helped provide clarity around this topic by adding an informational note to the definition of an electrically safe work condition which reads as follows:

"An electrically safe work condition is not a procedure, it is a state wherein all hazardous electrical conductors or circuit parts to which a worker might be exposed are maintained in a de-energized state for the purpose of temporarily eliminating electrical hazards for the period of time for which the state is maintained."

Establishing an electrically safe working condition is critical. While de-energizing equipment is an important goal, a worker will always have to dress in appropriate personal protection equipment (PPE) and use a test instrument to verify absence of voltage. Lock-out/tag-out procedures have to be followed which can range from simple to complex. In fact, there can be situations (e.g., verifying absence of voltage) when there isn't PPE with a rating high enough to protect the worker. For those situations, system designs and solutions that minimize the likelihood of an occurrence and the severity of injury should an accident occur must be incorporated.

Part 2 - Designing for a reduction in the likelihood of occurrence

The following examples illustrate the many layers of safety that can be employed to reduce the likelihood of arc flash, arc blast and/or shock:

  • ELECTRICAL ONE-LINE DIAGRAMS: An important part of a facility's electrical infrastructure life begins even before ground is broken. This document is developed and used by engineers, suppliers, inspectors, workers and designers. Workers could be put at risk if one-line diagrams are not maintained and power system capabilities reviewed and updated as they change over time.
  • BARRIERS: Adding a local disconnect next to a panelboard or industrial control panel (ICP) that is accessed frequently for service provides electrical workers with clear visible indicators that the panel or ICP has been de-energized when the circuit breaker or switch is in the off position. When required absence of voltage testing is performed, the likelihood of an incident has been reduced.
  • DISCONNECTS: By placing a circuit breaker or fuse and switch in its own enclosure next to equipment, electrical workers have a readily accessible disconnect to remove voltage and establish an electrically safe working condition.
  • VISIBILITY: Equipping a panelboard with a window that allows workers to visibly see the blades being disconnected aids in worker verification reducing the likelihood of an incident.
  • INDICATORS: The presence of voltage indicators employed on equipment provides electrical workers a visible indication of which side of the disconnect is energized and which isn't.
  • KNOWLEDGE: Information on the condition and maintenance of equipment can provide electrical workers details that are critical to safety when performing justified energized work. Knowledge of the equipment itself is critical to recognizing hazards.
  • WORKING SPACE: Sometimes safety doesn't come in the form of a product, it can simply be in the fact that a design provides adequate working space for the electrical worker to safely perform functions.

Part 3 - Designing for a reduction in the severity of injuries

When justified energized work must occur, minimizing the danger associated with electrical hazards to the point at which injuries may be minor can be designed into the system. To that end, there are a variety of ways in which the electrical industry is making efforts to reduce the severity of injuries to workers should an accident occur.

  • DECREASED CLEARING TIME: By placing a circuit breaker with arc reduction maintenance switch technology or a fuse and switch in its own enclosure next to an upstream of electrical equipment likely to be a part of justified energized work, provides reduced clearing times for arcing currents reducing the level of incident energy exposure. The achieved incident energy reduction downstream can be significant such that minimal PPE is required which could also decrease the likelihood of an event occurring.
  • GFCI shock protection: GFCIs are specifically designed to protect people against electric shock from an electrical system, and to monitor the imbalance of current between the ungrounded (hot) and grounded (neutral) conductor of a given circuit.
  • IEEE 1584 and arc flash calculations: New updates to the 2018 Guide for Performing Arc Flash Calculations offer significant changes that impact the way arc flash hazards in electrical systems are analyzed. More precise calculations help reduce the risk to employees and contractors.
  • Arc reduction technologies: Arcing faults that occur within equipment need to be cleared as quickly as possible. Arc flash reduction technology reduces clearing times of arcing fault currents should a problem occur when working on energized electrical equipment. Arc Quenching equipment can extinguish an arc flash in approximately 4 milliseconds. Eaton's Arc Quenching Magnum DS low-voltage switchgear is a great example of such equipment.

"We must incorporate system designs and solutions that minimize the likelihood of an occurrence and the severity of injury should an accident occur."
Thomas Domitrovich, vice president, technical sales

A trio of documents critical to safety

The electrical industry looks to three key documents from the National Fire Protection Association (NFPA) that strategically work together to help increase safety for electrical workers by providing guidance and recommendations:

  • NFPA 70 The National Electrical Code (NEC) provides installation requirements
  • NFPA 70E-2021 covers the topic of electrical safety in the workplace
  • NFPA 70B covers electrical equipment maintenance

In particular, NFPA 70E includes requirements for safe work practices to protect personnel by reducing exposure to major electrical hazards, including shock, electrocution, arc flash and arc blast. These requirements rely on the fact that an electrical system was installed in accordance with the NEC and that maintenance has been performed leveraging reference materials found in NFPA 70B.

Recent changes to 70E highlight how important it is to design safety into systems and provide more detailed guidance for electrical workers. For example, the document addresses when the estimated incident energy exposure is greater than the arc rating of commercially available arc-rated PPE. We now have guidance for the purpose of absence of voltage testing. The following examples of risk reduction methods could be used to reduce the likelihood of occurrence of an arc flash, thus reducing the severity of exposure:

  • Use of non-contact proximity test instrument(s) or measurement of voltage on the secondary side of a low voltage transformer (VT) mounted in the equipment before use of a contact test instrument, to test for the absence of voltage below 1,000 volts
  • If equipment design allows, observe visible gaps between the equipment conductors and circuit parts and the electrical source(s) of supply
  • Increase the working distance
  • Consider system design options to reduce the incident energy level

In addition, the latest version of 70E recognizes the newly updated IEEE 1584, a resource that the industry will continue to explore and apply to new power system analysis studies.

Smart Tools that Simplify and Save Time for Busy Data Center Professionals

For many of today's data center professionals, it seems that everything is always happening at once – whether it be protecting a growing number of mission-critical applications, managing highly complex and heterogeneous environments, or evaluating the newest data center solutions.

Adding to this daily challenge of multi-tasking, most companies are now undergoing the process of digital transformation. This means that they are deploying more technology with the same resources and flat budgets. This combination of factors leaves data center teams with severely limited bandwidth to support their operations.

The data center administrators, networking specialists and data center managers I meet often need extra help in order to deal with their ever-widening scope of responsibilities. With that in mind, I'm sharing some free tools that were designed to simplify daily planning, product selection and education tasks, while ensuring smarter long-term data center builds.

Smart Tools for Busy Data Center Professionals

Many data center vendors provide tools for customers, but they are often difficult to learn and use. We at Schneider Electric took a different approach and offer customers certain tools aligned to their needs around procuring, implementing and supporting data center physical infrastructure solutions.

Below is a quick list of top tools to help choose, monitor and manage power, cooling, racks and environmental control devices:

Data Center Planning – Schneider Electric's Data Center Science Center team has built online TradeOff Tools to help you quickly experiment with "what if" scenarios to help with critical planning decisions like understanding the cost implications of deploying different power and cooling technologies. These TradeOff Tools are web-based, mobile-friendly and help data center operations quantify their decisions using data and science.
Research-based Designs – Choose from a library of tested, validated, and documented reference designs that enable data center professionals to determine key project parameters such as criticality, density, efficiency and budget. Recent enhancements to this library include greatly improved search, filtering and sorting functions, a reference design "details" page that simplifies information access and summarizes design benefits, and an easy-to-use CAPEX cost estimator. The information from the library can also be shared via social media. Once an approved reference design is chosen, it serves as a starting point for site-specific deployment. Reference designs make data center revitalization projects go more smoothly, cost less, and operate reliably over the long run.

Easy Product Selection – Several important product selector tools exist online to help save you time and money. These selectors cover UPSs, battery upgrades and rack PDU configurators. The UPS selector, for example, specifies the equipment you need to protect your IT assets and recommends the right product based on your specific needs.

NEC 2020 enhances four foundational elements of service entrance and surge protection

Short circuit current rating

The 2020 change

The new requirement parallels changes that affected power distribution blocks (PDBs) from the 2017 cycle, but now addresses other types of termination devices as well. The update has far-reaching implications for manufacturers. Effective January 1, 2023, pressure connectors and devices for splices and taps must be marked "suitable for use on the line side of the service equipment" or equivalent.


The rationale for change

The 2017 label change only accounted for one type of solution used in that application. The update now requires marking all termination types, including PDBs, pressure connectors and devices for splices and taps used in these locations, as suitable for use on the line side of service equipment to assure connectors are tested for given locations in the circuit.



What might the future hold?

Manufacturers currently don't build devices for use on the line side of service equipment, so manufacturers and standards developers must quickly bring solutions to market. The requirement's effective date offers manufacturers leeway to bring products up to speed.

"The changes passed enhance protection for persons and property at service entrance, potentially the most dangerous place in the power distribution system."
Thomas Domitrovich, Eaton vice president, technical sales

Safety disconnect (formerly the firefighter disconnect)

The 2020 change

Language now exists in Article 230.85 for emergency disconnects on the exterior of one- and two-family dwelling units so that first responders may quickly disconnect power to a structure. Language in Article 445.18 also addresses emergency generator shutdown.

The rationale for change

Aside from fire dangers, first responders often must account for electrical hazards during emergencies. Fires are chaotic, with firefighters rushing to ventilate buildings on rooftops, breaking through windows and opening walls in seconds. With that, there's a real danger of coming in contact with energized conductors and equipment.

Typically, first responders look to turn the power off before entering a blaze, but many homes' panelboards are in basements. Terminating power at the transformer, which could be atop a pole, is not something any untrained person should attempt. This change mandates placing emergency disconnects near the service entrance equipment outside of a structure. 

What might the future hold?

Concerns were raised during requirement debates that safety disconnects allow anyone to terminate the power to a home. The NEC's response was to allow the installation of disconnect locks to thwart unauthorized power access. While the locks will not impede firefighters or other first responders and may provide a level of comfort to the homeowner, contractors will still have to explain the expense of safety disconnects, especially in locations where it's not common practice to add outdoor service panelboards. When bidding on new jobs, technicians should stress the importance of safety to justify costs to consumers. 

Line side barriers and the six disconnect rule

The 2020 change

What many refer to as "the six disconnect rule" was modified per Article 230.71 such that service panelboards without a main and six or fewer disconnects will no longer be permitted. Hazards associated with six disconnects without a main in a service panelboard have always been a concern; 2017's changes in NEC Articles 110.16, 240.87, 240.67 and 408.3 during the 2017 review cycle furthered that awareness and inspired more change during the NEC 2020 development process.

The changes in the latest cycle provide options on leveraging up to six disconnects instead of a single main overcurrent protective device (OCPD), with a how-to section outlining four options:

  • Separate enclosures with a main service disconnect
  • Panelboards with a main service disconnect
  • Switchboards with only one service disconnect and barriers separating each vertical section
  • Service disconnects in switchgear/metering centers with disconnects located in separate compartments

In addition, line-side barrier requirements expanded to service equipment beyond panelboards and switchboards.

The rationale for change

Exposing hazards

The NEC changed Article 408.3 in 2017 to require barriers on service entrance panelboards, recognizing that adding line side barriers on panelboard service disconnects may not be possible with six disconnects used in the same panelboard. This decreased the likelihood of workers coming in contact with energized terminations on the line side of the main service OCPD or switch. However, one panelboard with six means of disconnect with no main circuit breaker results in electrical workers lacking the ability to apply barriers to the line side of each because the line side is a bus. The 2017 NEC update included an exception for these types of applications.

The 2017 Code focused on panelboards, switchboards and low voltage assembly solutions, but warranted an exception since technicians can't barrier the line side of six disconnects in a panelboard. Due to the new changes in 230.71, the NEC removed the exception in the 2020 update by including transfer switches, feasible disconnect switches and others with catch-all language. Now all equipment must have a barrier on the line side.

Better personal protection

NEC 2017 changed Article 110.16 to require marking service equipment with available fault current, clearing times and date of installation to help determine personal protective equipment (PPE). With six disconnects used in the same panel, six distinct clearing times must be labeled on the equipment. This update to what I believe is an obvious safety hazard has inspired electrical professionals to look at installations more closely. Since exposed energized buses in panelboards do not have upstream OCPDs, the NEC 2020 changes to labeling requirements raise awareness of hazards associated with six disconnects in the same enclosure.

Arc reduction

Arc reduction requirements have expanded during every review cycle since their introduction in 2011. While not for service equipment per se, this requirement is intended for any circuit breaker or fuse 1200 amps and higher and recognizes such applications are prone to high incident energy due to the longer clearing times of devices at these ampere levels.

By raising awareness of service entrance equipment hazards that lack upstream OCPDs, the changes help reduce the likelihood of exposure to an energized bus.

What might the future hold?

Aside from manufacturers creating new code-compliant products, technicians may need to review their designs against new requirements and will likely need to change the way they plan future projects. Some believe the changes could impact businesses financially. But I think resourceful contractors will find ways to meet the Code while becoming more cost-efficient.

"Technicians may need to review their designs against new requirements and will likely need to change the way they plan future projects."
Thomas Domitrovich, Eaton vice president, technical sales

Surge protection

The 2020 Change

The NEC recognizes in Article 90.1(A) that the purpose of the Code is the practical safeguarding of persons and property from hazards arising from the use of electricity. Updates to surge are twofold. First, Article 242, titled "Overvoltage Protection," does not add new requirements but rather consolidates surge requirements from around the NEC to bring attention to performance issues that align with circuit applications. Secondly, Article 230.67 now mandates services supplying dwelling units shall be provided with a surge protective device (SPD) as an integral part of equipment or located immediately adjacent, either Type 1 or Type 2 SPD.
The rationale for change

The surge requirement change is all about usability; the NEC has made the requirement easier to navigate and implement, which increases the likelihood of proper installation.

Protecting people is table stakes and a key driver for surge protection clarification and expansion. The requirements provide for life safety products like AFCIs, GFCIs, smoke detectors and other protection devices. But I could make an argument that the Code goes beyond life safety to include protection of property. Loss isn't always devastating; something as small a losing a TV or appliance to surge isn't life-threatening, but it is a nuisance. Insurance companies take the brunt of surge losses. While insurance companies don't often publish payout amounts due to proprietary information, my best guess is that it's millions of dollars. This, of course, results in higher insurance premiums paid by homeowners, something these requirement changes look to help prevent.

What might the future hold?

Not all surge devices are created equally. Devices feature different parameters, such as varied threshold voltages, but no performance-related requirement currently exists. I believe the NEC will push to mandate higher-quality products by establishing SPD performance requirements in the future.

Additionally, I feel the NEC should look to protect digital connections. For instance, we can protect the power supply for a TV, but surges also travel down data cables to cause damage. There's potential for the NEC to discuss this aspect of power protection as well.
Looking to the 2023 code review cycle

For years, the NEC has anticipated stronger protections for those who work on service equipment. With the updates passed by the NFPA, the Code enhances protections for workers and the equipment they service. As with any requirement update, feedback from professionals in the field is extraordinarily important. I look forward to seeing how technicians implement the new requirements so that we may refine the Code in 2023.

Further, I feel it's vital that everyone in the electrical field explore articles in their purview that could benefit from enhancement. Many 2020 updates were inspired by professionals who knew that more could be done to enhance safety, so I know the industry has the capacity to make proactive changes. With that, I encourage everyone in the industry to look to the requirements they know need improvement and start conversations now in preparation for the 2023 code review cycle.

Powering tomorrow: grid modernization

The convergence of technology advancement and complex power challenges
The electrical grid has served businesses and consumers for over 100 years. Utility system planners, operators and maintenance personnel have always faced challenges, but never have they compounded as rapidly as they are now. From point of generation to consumption, power requirements are quickly evolving.

A combination of factors usher in a new power landscape

Everywhere you look, there are unique dynamics at work. Infrastructures, components and equipment are aging. Weather events and natural disasters cause billions of dollars of infrastructure damage. Cyber threats are on the rise. Renewables' share of generated power grows yearly. Customers expect to interact with utilities for more control of their electricity use thanks to the prevalence of connected devices. State and federal governments continue to introduce new energy legislation. All the while, an aging workforce across many industries is creating recruitment difficulties.

Every power challenge is unique, with its own set of complex variables. As these factors converge, complications amplify to a point with only one viable option: utilities must modernize to keep pace with change.


How utilities can manage change on the horizon

The future of power generation is responding to the fundamental shift in how consumers use power and how utilities provide it. Renewables like wind and solar are increasingly responsible for greater shares of generated power. Smart grid technologies deliver real-time and up-to-the-minute information. Batteries now provide more than reserve power, with load shifting and the sale of power back to utilities becoming real cost saving and revenue enhancement options.

These shifts in generation and consumption mean utilities must work to modernize operations. And those who embrace new technologies and connected devices stand to see efficiency gains and improved profitability.

Data and analytics garnered from intelligent technologies and connected devices are laying the groundwork. However, new system components often introduce unforeseen compatibility and management issues. So utilities not only need modern solutions – they need modern solutions that work with what they've already got.


A foundation that supports change

Utilities are being asked to do more than ever, with less than ever. Managing more power sources with less budget, serving more people with fewer people and doing it all more efficiently and sustainably with less margin for error.

To help address these challenges, utilities benefit from a partner with a proven track record of creating smart, adaptable power systems. At Eaton, every product and service we offer is built on a foundation of intelligence, experience and security.

NEC 2020 to help better identify & understand equipment history

 Members of the National Fire Protection Association (NFPA) have now completed the annual NFPA Conference and Expo, where a considerable amount of debate occurred around the topic of reconditioned equipment. Until now, this issue was not a focus of the National Electrical Code (NEC). The new updated code brings clarity and transparency to the table by educating customers around the equipment they're buying and installing. In my opinion, the electrical industry must work together to take this foundation to the next level. We now have a platform from which clarity and transparency pertaining to reconditioned equipment can be expanded upon to help buyers and sellers of refurbished electrical safety devices develop and adhere to best practices for safety's sake.

The use of reconditioned equipment and its safety implications

It's common for electrical professionals to source reconditioned equipment, especially contractors on large jobs or on those projects where a quick turn-around on older equipment is needed. The practice can be cost effective and, in instances where older legacy systems require devices that are no longer manufactured, often necessary to solve an immediate requirement. But with many counterfeit devices in the supply chain and devices and equipment that may have experienced flooding or other abnormal damage, the NEC has made it clear that safety must take a higher priority.

With that, NEC 2020 will end its silence on this topic and seek to assure proper reconditioning of electrical equipment. New requirements for are found across 20 sections of the document, with changes making it clear what equipment can and cannot be refurbished for safety reasons.

"A basic understanding of the term "reconditioned" is critical to success."

Thomas Domitrovich, Eaton vice president, technical sales

The one critical rule

Though 20 new requirements are under consideration, one is most important in my opinion: 110.21(A)(2). It states equipment must be identified as reconditioned and the original listing mark removed (though the original nameplate may remain in place). This means third-party testing marks (such as the UL listing mark) must be removed and the device identified as reconditioned.

This addition is tremendously important for the Authority Having Jurisdiction (AHJ) to help them identify equipment that has been refurbished or reconditioned and ensure these NEC requirements are enforced. These changes raise the bar of safety for refurbished equipment and those that provided refurbished equipment. Refurbished products brought to market will carry the transparency needed for the specifier, installer, and ultimately the owner. A basic understanding of the term "reconditioned" is critical to success.

What does "reconditioned" mean?

As with many changes in the NEC, good definitions are necessary for proper enforcement of requirements. Discussions will occur across the industry to understand this new term. Three different Code-making Panels assembled what we have today as a definition for "reconditioned." These technical committees have done their part to create, what I believe is, a solid definition:

"Reconditioned equipment is electromechanical systems, equipment, apparatus, or components that are restored to operating conditions. This process differs from normal servicing of equipment that remains within a facility, or replacement of listed equipment on a one-to-one basis."

As with most new changes, especially those as significant as these, NEC 2020 will benefit from public review as it rolls out across the country. Many electrical professionals will learn of what NEC 2020 now requires and develop educational materials that support it. As more people review the updated code, the more we'll see ideas arise on how to improve this text. This process is one of the best in the industry – as the code evolves over time, it improves. My colleague, Jim Dollard, IBEW Local 98 in Philadelphia, said it best: "It's a solid definition, it is comprehensive. The first sentence clarifies that reconditioned means "restored to operating conditions." That means the equipment was not useable. This also clarifies that "used equipment" that is in operating condition is not considered to be "reconditioned equipment." The second sentence is extremely important. This text provides clarification with respect to "normal servicing of equipment that remains within a facility or replacement of listed equipment on a one-to-one basis." Any "normal servicing of equipment that remains within a facility" is not reconditioned. Keep in mind that a facility is a single building, a campus or a network of cell towers for example. Replacement of "listed equipment on a one-to-one basis" clarifies that piece of equipment that is not in operating condition can be restored to operating condition through the replacement of "listed equipment on a one-to-one basis" and is not considered to be "reconditioned equipment."

Here is my opinion on a breakdown of each aspect of the definition. Keep in mind that your Authority Having Jurisdiction (AHJ) is the final say on all of these requirements including the interpretation of the definition.

Electromechanical systems

"Electromechanical systems, equipment, apparatus, or components that are restored to operating conditions." This first sentence is very broad. No matter the system, equipment, apparatus, or component, the key portion of this sentence lies in these four words; "restored to operating conditions." This means the equipment was not operable and something had to be done to return it to a functioning state.

In my opinion: If an electrical contractor removes a fully operational panelboard from a facility to either upgrade or install a larger panelboard, the contractor may reinstall that panelboard elsewhere in the facility. The panelboard is clearly used equipment and not reconditioned because no steps were taken to repair or modify it and return it to an operating condition.

Normal servicing

Continuing from the definition, "This process differs from normal servicing of equipment." There are numerous events that can affect devices including flooding, fires and other extremes. Servicing this equipment after these events will beg the question of whether or not this is "normal servicing." We won't find a definition in the NEC for "normal servicing" as commonly used, well-understood terms aren't defined. The question will remain for many though as to what exactly is meant by the use of the term "normal" in this context.

In my opinion: We have to apply common sense here. Equipment that's been underwater, in a fire, or other similar event is not normal in my opinion. Servicing equipment per manufacturer instructions for updates or maintenance reasons are normal activities. Equipment manufacturers help to define "normal" by working with service departments to identify common repairs performed on a regular basis. 

Facility

"That remains within a facility." Knowing the history of equipment is the next step of this definition. It's easier to understand the history of equipment that was purchased for and remained in a single facility during its entire life. This history is important for safety. Repairing and maintaining this equipment is not considered, "reconditioning." We can't forget too that we're talking about equipment that is ". . . restored to operating conditions."

In my opinion: This asserts that the owner of equipment has a better understanding of its history. If a technician removes a device from a facility and that device is in working order when reused within that same facility, that's use of used equipment. This equipment was not in a state of condition that requires someone to return it to operating conditions. If the condition of the device is not known, steps may have to be taken to modify the equipment to replace components to raise the level of confidence that this equipment is in operating conditions addressing areas of concern. This would then meet the definition of reconditioned equipment.

One-to-one basis

"Replacement of existing equipment on a one-to-one basis." The code making panels took time to ensure that the act of replacing components within equipment per manufacturer instructions does not fall under the reconditioned equipment umbrella. Contractors and IT managers often replace existing devices for many reasons, such as equipment end-of-life or for assembly capacity increases.

In my opinion: If equipment is listed for the same purpose as the original device being replaced, it's done on a one-to-one basis and, therefore, is not reconditioned. Let's take the example of an electrician replacing a circuit breaker in a panelboard with another per manufacturer instructions. The replacement is a one-to-one example and the application was not reconditioned. On the other hand, should this replacement occur in conjunction with cleaning the internal bus and other components within the enclosure after an event such as a flood, fire or similar, we're looking at refurbished equipment. 

What clarity means for the industry

These code changes were upheld at the annual meeting amidst extensive debate. Our electrical industry understands the challenges and safety concerns around reconditioned equipment. The requirements for reconditioned equipment were overwhelmingly supported on the floor of the annual meeting.

Proper governance starts with ensuring education for those focused on electrical safety. Organizations like the International Brotherhood of Electrical Workers (IBEW), the National Electrical Contractors Association (NECA), Independent Electrical Contractors (IEC), the International Association of Electrical Inspectors (IAEI) and others will be working to update and create their curricula based on these new changes. Consistency in what we all teach is important to success

Don't wait for the NEC. Here's what you can do now.

As with any NEC safety change, this will be a journey with many growing pains along the way. Future efforts will seek to clarify, expand and correct requirements for used and reconditioned equipment. This journey will continue over many review cycles.

So, what can you do to protect yourself? I believe buyers and suppliers of reconditioned devices can do more to assure safety today:

Suppliers – differentiate yourself from others

  • Pay close attention to product standards and perform tests that establish performance, even if standards do not exist, and document it all. Share this with your customers as a differentiator. This helps bolster the supplier's brand image and create safer products that customers ask for by name.
  • Engage with the industry and join NEC and other requirement-making institution discussions. It helps to listen in on industry concerns, get first-hand feedback and refute claims you know are incorrectly positioned. It's also a great opportunity to highlight your safety processes, which may also influence future amendments.

Buyers – know where products are sourced

  • Buy only from reputable resellers. Devices purchased from unauthorized distributors who lack important safety certifications carry tremendous risk. Remember, the solutions you install in a facility reflect on you. Do your due diligence.
  • Note the products the NEC states cannot be refurbished. Less reputable resellers do attempt to sell molded case circuit breakers and other safety devices that can't be reconditioned. It's up to you to know the facts and act accordingly.
  • If a project bid includes reconditioned devices, make sure your customer is aware. Remember that reconditioned devices are now labeled as such with third-party listing marks removed, so they're easily noticed. Some clients may not take kindly to reconditioned devices after the fact.


While creating requirements for reconditioned equipment is in its infancy, understanding the differences between used and reconditioned equipment is a great first step toward helping educators, buyers and sellers ensure the safety of people and equipment.

OSHA Seeks to Increase Awareness of Workplace Hazards in Electrical Industry

OSHA wants employers to work to reduce the number of serious injuries, illnesses, and fatalities among engineers, electricians, and other professionals who perform electrical operations 

The U.S. Department of Labor's Occupational Safety and Health Administration (OSHA) is seeking to raise awareness of hazards in the electrical industry in Kansas, Missouri, and Nebraska. OSHA wants employers to work to reduce the number of serious injuries, illnesses, and fatalities among engineers, electricians, and other professionals who perform electrical operations, including work on overhead lines, cable harnesses, and circuit assemblies.

OSHA has resources to help keep workers safe from industry hazards, such as electrocutions, falls, fires and explosions. Its Recommended Practices for Safety and Health Programs can assist employers with identifying and fixing hazards before they cause serious or fatal injuries.

From January 2015 through September 2018, OSHA conducted inspections in the three states after reports of 15 worker hospitalizations and two amputations. Six electrical and wiring installation contractors suffered fatal injuries between October 2012 and September 2018.

"Working with electricity can be safe if employers provide workers with adequate training, and implement appropriate systems to reduce the risk of workplace injuries," says OSHA Regional Administrator Kimberly Stille, in Kansas City, Missouri.

OSHA's On-Site Consultation Program offers no-cost and confidential occupational safety and health services to small- and medium-sized businesses to identify workplace hazards, provide advice for compliance with OSHA standards, and assist in establishing and improving safety and health programs. On-Site Consultation services are separate from enforcement and do not result in penalties or citations.

NEC 2020 code new standards in GFCI protection

During the recent 2020 code review, panel members of the National Electrical Code (NEC) approved changes to ground fault circuit interrupter (GFCI) protection. Those changes dramatically reduce the dangers associated with electrical hazard and shock. The most significant change is the increase of amp protection ratings across all receptacle outlets, both indoor and outdoor, wherever GFCI protection is required. In this blog, I'll discuss how that change informs:

GFCI language expansion
Better protection for basements
Safer equipment maintenance for workers
Safer outdoor outlets
Sweeping global language changes
Further expansion of 50-amp protection

Some updates highlighted in this discussion apply to long-standing requirements. With that, a need for further clarity may still exist in the Code. However, I can say without hesitation that the NEC's 2020 GFCI updates significantly enhance electrical safety for homeowners and electrical workers alike.


GFCI language expansion

The 2020 change

Code-making panel 2 (CMP 2) updated text to read, "All 125-volt through 250-volt receptacles installed in the locations specified in 210.8(A) (1) through (11) and supplied by single-phase branch circuits rated 150 volts or less to ground shall have ground fault circuit interrupter protection for personnel." In layman's terms, the NEC removed amp values across all amp-rated receptacle outlets requiring GFCI protection in the areas listed in this section.

The rationale for change

NEC 2017 language only accounts for 15- and 20-amp receptacle outlets for dwelling units. During 2020 code review meetings, panel members agreed that hazards always exist; if 15- and 20-amp receptacle outlets present a hazard, that hazard also exists on 30-amp and higher receptacle outlets. However, it was difficult to understand the likelihood of a hazardous occurrence when weighed against expanded requirements. Recent home-based electrocution accidents – a 10-year-old girl behind an energized appliance, a child in Oklahoma retrieving a pet behind a clothes dryer, a 10-year-old Houston boy playing hide and seek — helped panel members realize the need for change. In light of these tragic events, we now have a requirement that sets a higher standard across more areas of the Code, though there are some exceptions discussed later in this blog.

What might the future hold?

The NEC mandates GFCI protection in many areas of the home: bathrooms, garages, outdoor receptacles, crawl spaces, basements, kitchens and anything within six feet of a sink or water source. While that may seem like a lot, the entirety of a home is not covered. The reality is when people have a problem with a tripped circuit, it's entirely possible they'll use an extension cord to plug into a receptacle outlet that's not GFCI protected. Doing so does nothing to eliminate the original hazard potentially caused by the device in use. I hope that NEC members account for the human factor and require GFCI coverage throughout the home during the next code review.



Better protection in basements

The 2020 change

The NEC expanded GFCI protection for dwelling units with basements both finished and unfinished.

The rationale for change

Often afterthoughts that present unique hazards, basements are typically not as well maintained as other areas of the home. Further, environments are often wet and damp, and moisture is a great conductor. These code updates help ensure that accidents due to factors such as leakage current and contact with water are considerably lessened or eliminated.

What might the future hold?

Many rooms in a home are already required to have GFCI protection. While it feels like the most logical code progression, others in the industry still pushback on requiring GFCIs throughout a home claiming financial concerns or installation problems. As with the parental language update, I believe this code change can inspire discussions to include GFCIs throughout the home.


Safer equipment maintenance for workers

The 2020 change

The NEC expanded GFCI protection under Article 210.63(A) for HVAC equipment and Article 210.63(B) for indoor service equipment and indoor equipment requiring dedicated space.

The rationale for change

Equipment location is at the crux of this update. While HVAC equipment in the basement is covered now that all basement circuits are GFCI protected, HVAC equipment located in attics and other areas would likely not have GFCI protection. CMP 2 recognized that many HVAC areas are typically tight working spaces where technicians perform justified energized work (they can't troubleshoot a de-energized circuit). In essence, the update assures equipment requiring service has a GFCI-protected receptacle outlet for ready access.

What might the future hold?

Because this is the NEC's first venture into expanding 210.63, I expect some inspectors and contractors may not see eye to eye on code language. Industry discussions across the country and during future review cycles will help the NEC make future improvements.


Safer outdoor outlets

The 2020 change

The NEC updated the Code for outdoor outlets supplied by single-phase branch circuits rated 150 volts to ground or less, 50 amps or less. Key to this update: it extends beyond receptacle outlets to include all outlets. Now all hard-wired equipment falls under the Code's purview.

The rationale for change

One downfall of the electrical business is that it's more reactive than proactive, with accidents often the catalyst for change. Numerous incidents inspired this code change, including an accident involving a 12-year-old boy who jumped over a fence and touched an AC condenser unit with an electrical fault. The outer metal housing was electrified and the child was fatally electrocuted immediately upon coming in contact with the condenser and fence simultaneously.

What might the future hold?

GFCI technology is unforgiving in that it's built to detect even the slightest power variance, and when expanded to include outlets impacting new types of loads, questions arise. With GFCIs installed, leakage-current trips may be near constant, rendering large equipment unusable. In the future, I hope industries rethink products with acceptable leakage current, hertz and frequency values to reduce future compatibility issues.

Further, this change will likely spur discussions related to current GFCI requirements focusing only on receptacle outlets. Hardwiring equipment does not eliminate the electrical hazard. I venture someone will propose public inputs during the next code-review cycle to challenge details about receptacle outlets versus outlets requiring GFCI protection.



Sweeping global language changes

The 2020 change

The NEC reviewed all locations with a GFCI requirement and aligned with Article 210.8. Updates were made in many locations to include text, such as "in addition to the requirements of 210.8" and similar, to clarify language and eliminate misinterpretation.

The rationale for change

The NEC included Article 210.8(B) for other than dwelling units in 1993. Before its inclusion, builders relied on requirements in later chapters of the Code (chapters five through seven), for safety guidance. For example, RV Park GFCI requirements added in 1978 aligned with 210.8's 15- and 20-amp receptacle outlet GFCI protection philosophy at that time. NEC 2017 created some confusion when 210.8(B) increased GFCI protection requirements beyond 15- and 20-amp receptacle outlets for other than dwelling units. This presented a challenge: a chapter two requirement applied a generally wider level of GFCI protection. This conflicted with chapter five, which has less coverage of GFCI protection.

The correlating committee recognized similar conflicts exist across industries and formulated a task group that challenged every code panel to look at their GFCI requirements and attempt to align them with 210.8's 50-amp increase.

What might the future hold?

Each code panel performed their review; some made changes, others did not. There is room for discussion in future revisions of the Code regarding shock hazards in the special other than dwelling unit applications. I believe the NEC will soon increase its focus on GFCIs and hopefully add clarity as each application in chapters five through seven approaches GFCI protection differently.



Further expansion of 50-amp protection

NEC articles to watch

While representatives in agriculture and RV industries have valid concerns about nuisance tripping, I believe the NEC should revisit Article 547 for agricultural buildings and Article 551 for RVs and RV parks to address valid shock hazard concerns and consider increasing GFCI protection to 50 amps.

The rationale for change

Farming and RV industries rely on circuits that operate at well over 20 amps, yet no safety requirements exist. Much of the equipment used in these industries can be quite old with leakage current a serious concern. In my opinion, the Code lacks parity in how safety requirements exist in some industries and not in others. That must change.

The studies needed to promote change exist. The University of Iowa and the University of Nebraska have uncovered many incidents where farmers lost their lives due to faulty agricultural electrical equipment. Further, RV "hot skin," a situation where the entirety of an RV's outer housing becomes energized due to electrical faults, can kill in an instant, as was the case when a young boy died when touching an RV. If RV parks and farms running 30- to 50-amp receptacles without GFCI protection is not deemed a concern worth addressing, how can anyone claim running 30- to 50-amp receptacles outside of dwelling units is a hazard? Common sense dictates both are hazards and change is necessary.

What might the future hold?

I appreciate that equipment compatibility issues on farms and at RV parks may require much time and financial capital to resolve. However, I cannot condone sitting idle as lives are lost. I hope a series of discussions during the next code review cycle inspires commissioning an NFPA Fire Protection Research Foundation study to further understand the implications of expanding GFCI protection beyond 15 and 20 amps in RV parks and farms. Let's study the problem, understand the challenges and determine solutions that increase safety.



Let's continue to make great strides in safety

Extending the amp requirement across all receptacles is a milestone that cannot be understated — it will change how industries work. Many of the changes I've discussed represent the first step toward increasing safety, with industry feedback being critically important in making improvements in 2023. With that, we already have some of the data needed to suggest the changes desperately needed in the RV and farming industries. I call on my NEC colleagues to begin safety conversations now so that we as a group can protect more lives from electrical shock.

The National Electrical Manufacturers Association (NEMA), Rosslyn, Va., has released the first in a new series of publications intended to provide guidance on the evaluation, specification, and use of surge protective devices (SPD) in low-voltage power distribution system applications.

"Surge Protective Device Specification Guide for Low-Voltage Power Distribution Systems, Part 1" (NEMA SPD 1.1-2019) is written for those who use or specify SPDs and others affiliated with the low-voltage SPD marketplace, "so that uniformity of specifications and parameters will improve comprehension, application, and utilization," said Saad Lambaz, Global Standards Manager at Littelfuse, Inc., NEMA Low Voltage Surge Section Member.

The guide includes SPD ratings related to the operating system and performance, a specification checklist, and information on surge current ratings, modes of protection, and general grounding practices.
