Trump's Order to Secure Power System Met with Favor, Uncertainty in Utility Industry

Utilities remain uncertain on how the order intended to secure the bulk power system from foreign cybersecurity attacks will impact current projects and the installed infrastructure base. 

 U.S. President Donald Trump signed an executive order on May 1, 2020, that establishes oversight of foreign-made equipment used in the United States bulk-power system. The order stated that Energy Secretary Dan Brouillette would assemble a task force to examine current procurement policies, identify threats to security, and establish risk-management protocols to inform future procurement.

This direction comes as little surprise to the power industry, following the Administration's previous crackdowns on telecommunications providers sourcing foreign-made systems and equipment deemed by the Secretary of Commerce as posing a national security risk.

The order will affect future power equipment purchases and potentially existing installed and commissioned components at the generation and transmission level. It builds on a July 2019 North American Electric Reliability Corp. request for bulk-power system asset owners to inventory telecommunications devices manufactured by Chinese technology companies, as part of an investigation into components made by Chinese firms Huawei and ZTE Corp.

"This is much broader; it reaches across the entire industry, not just the telecommunications infrastructure," said Jason Johns, an energy market attorney with Stoel Rives, LLP. "At the same time, it is particularly broad and imprecise in terms of its application."

Still, many electric utility industry stakeholder groups took a favorable stance toward the order. In a May 1 statement, Edison Electric Institute President Tom Kuhn said, "EEI and our member companies appreciate that President Trump, through his new Executive Order, continues to make energy grid security a priority for his Administration and our nation. We have long maintained that grid security is a shared responsibility, and addressing dynamic threats to the grid requires vigilance and coordination that leverages both government and industry resources."

"This is primarily about information systems," Johns said. According to a 2018 report by Protect Our Power, a not-for-profit organization focused on advancing cybersecurity in the U.S. power grid, the convergence of IT and OT poses the most significant threat to the security of bulk power. The report, co-authored by Ridge Global, states that "[IT/OT] integration can provide greater and more efficient ease of access for a wide array of malicious actors if modern IT/OT system components are not properly secured across their 'cradle-to-grave' life-cycle."

The report warns of the "globally distributed, highly complex, and increasingly interconnected set of supply chains," including products and services, that pose a risk at many points. Additionally, it states that "the process of maintaining hardware and updating or 'patching' software products that support IT/OT systems within the U.S. electric industry also represent critical points of vulnerability." Integration, maintenance, and updates pose potential areas of risk once installed.

"A lot of the connected devices [used by utilities] are assembled in the United States," said Jeff Pack, a senior product engineer and cybersecurity expert with POWER Engineers, "but each component will have something, whether it be memory chips, boards, or processing chips, that are manufactured in foreign lands." Pack indicated that this is an area that we can start to investigate relatively quickly.

The value this order will add to existing cybersecurity frameworks, namely NERC CIP, and particularly CIP-013, which establishes supply chain standards, is still unclear. "Perhaps after the Task Force is able to issue some guidance or directives, we will be able to determine if the Executive Order provides any risk reduction or resilience to the BPS beyond what the scope of CIP-013 provides," Pack said.

The degree to which the order will establish oversight and regulation of pre-installed infrastructure is also unclear. "It could pose substantial challenges to utilities if asset owners are required to rectify existing installed infrastructure that may have technological components embedded from one or more 'adversarial countries,'" said Chuck Newton, principle at Newton-Evans Research, who tracks power equipment supply chain.

At the bulk power level, experts say many utilities are already highly informed about the equipment that exists today. "Utilities are mindful of components and equipment, and where many of the underlying parts originate. Many utilities, especially larger ones, have done a lot of supply chain investigation," Pack said.

According to Newton, very few Chinese or Russian assets exist in the field today. "Utilities are not willing to invest in Chinese equipment at this time," he said. "Over the past several years there have been some new plants built to produce large and very large power transformers in the United States, which include SPX, Hyundai, VA/GA Transformers, and MEPPI. Subsequent M&A activity has expanded foreign ownership of [United States-based] plants."

Pack was optimistic that "If [utilities] are directed to take a risk-based assessment, a lot of existing equipment could be grandfathered in and left in place if due diligence was done at the time of procurement."

Uncertainty Rules

"Right now, the biggest impact is uncertainty across the industry as far as the impact it will have on transactions," Attorney Johns said. "However supportive the industry, clarity must be provided as soon as possible, long before the 150 days allotted to the [Secretary of Energy Brouillette's] task force."

This can create perplexity for anyone who is currently sourcing components. "What about those facilities that have already signed agreements before the May 1 order? How are those impacted? Utilities will struggle to meet their current timelines, and capital expenditure planning will be impacted," Johns said.

POWER Engineers' Pack points out that the devil is in the details. "Overall, the order is probably overdue, but right now there are a lot of missing details as to what types of assets, owned by who is involved and how [Secretary Brouillette's] task force starts to put its arms around [the order] and issue guidance or directives on how it will be implemented. If the task force takes a risk-based approach, we won't see as much disruption to the industry, but right now, we don't know."

Do you know how to calculate branch-circuit loads?

Mike Holt, National Electrical Code (NEC) expert discusses how to calculate branch-circuit loads in his latest article:

Article 220 of the 2020 National Electrical Code (NEC) contains the requirements for calculating demand loads for branch circuits, feeders, and services. Table 220.3 lists references for branch-circuit calculations for specific equipment in Chapter 4.

Calculate your branch-circuit, feeder, and service loads using nominal system voltages, (e.g., 120V, 120/240V, 120/208V, 240V, 277/480V, 480V) unless other voltages are specified [Sec. 220.5(A)].

What if you do a calculation and get a fraction of an amp? You can round the answer to the nearest whole number, with decimal fractions smaller than 0.50 dropped [Sec. 220.5(B)].

Calculate the floor area from the outside dimensions of the building, dwelling unit, or other area involved [Sec. 220.11]. For dwelling units, the calculated floor area does not include open porches, garages, or unused or unfinished spaces not adaptable for future use.

COVID-19’s Impact on the Construction Industry

 Cities halt construction while country faces economic downturn

As the coronavirus disease advances across the United States, various industries and nearly all aspects of the supply chain continue to be impacted, including the construction industry – and by default, skilled workers, electricians, engineers, and more.

According to a Boston Globe report from March 16, Boston Mayor Martin J. Walsh ordered a stop to all construction projects within the city in an attempt to slow the spread of the virus, the first move of its kind in the nation. Chief Executive Officer of the Associated General Contractors of America (AGC) Stephen E. Sandherr responded in a press release, arguing the city's actions will undermine the construction industry's efforts to add hospital capacity.

Additionally, Sandherr said construction workers already take many precautions to protect themselves and others from the spread of infection, including the use of personal protective equipment (PPE), gloves, and increased hygiene. "Given the precautions already in place, halting construction will do little to protect the health and safety of construction workers," he said in the release. "But it will go a long way in undermining economic vitality by depriving millions of workers of the wages they will need over the coming days. At the same time, these measures have the potential to bankrupt many construction firms who have contractual obligations to stay on schedule or risk incurring significant financial penalties."

Other states and cities are bound to see significant construction decline, as well. According to a March 19 report from Engineering News Record (ENR), all construction operations in the state of Pennsylvania were ordered to stop, which includes heavy/civil, building, institutional, residential, and specialty trade work. Likewise, New York City officials are calling for a pause to non-essential construction within all five boroughs, a Curbed New York article from March 20 says. A Chicago Tribune story also predicts a slowdown to Chicago's 10-year construction boom due to added safety precautions being implemented on job sites in an attempt to avoid a complete construction shutdown. Meanwhile, in California, a March 20 article from Politico says plans are underway to deploy thousands of construction workers in order to retrofit hospitals, hotels, and buildings in response to the outbreak.

Robert Dietz, chief economist for the National Association of Home Builders (NAHB), is predicting coronavirus will cause a sharp economic downturn that may also be short. 2Q 2020 GDP growth will be markedly negative and probably the country's worst performance since 3Q 2008, during the great recession. A weak 3Q will likely be followed by a rebound at the end of 2020.

Even if cities or states do not call for direct halts to construction, the effects of coronavirus as a pandemic are far-reaching. According to a report from Construction Dive, Chief Economist for Dodge Data & Analytics Richard Branch estimated that 30% of building products in the U.S. are imported from China, making it the nation's largest single supplier. While China seems to be slightly rebounding from the disease, its decreased manufacturing output is still expected to impact construction in the United States.

On March 20, AGC held a webinar called "The Latest Developments on the Coronavirus and What That Means for the Construction Industry." Hosted by Sandherr, several national staff members addressed various aspects of the industry, including safety measures, contracts/legal information, economic impacts, and more. Following is a summary of some of the webinar's key points.

Member survey results. AGC's Chief Economist Ken Simonson delivered coronavirus survey results from the organization's members, with a total of 909 responses as of March 19. Notable results include 28% of respondents being asked by an owner or government agency to stop current work; 11% were asked by an owner or government agency to stop future work; and 22% received a notice from suppliers that deliveries will be late or cancelled. Regarding project delays or disruptions, 16% experienced a shortage of materials, equipment, or parts; 11% saw a shortage of craftworkers, including subcontractors; 18% saw shortage of government workers; and 8% received information that an infected worker has potentially infected a worksite.

Positive and negative economic impacts. The COVID-19 outbreak is expected to bring several long-lasting and short-term negative consequences. Simonson said these may include disruptions to work or cancelled projects; potentially less demand for "non-essential" projects like offices, entertainment, and sports facilities; reduced/missed payments by owners; and a slow economic rebound across many industries. On the positive side, Simonson cited selected new projects to respond to the crisis, like healthcare and lodging; substantial price reductions for commodities like fuel; and a slow rebound for commodity prices.

Safety standards. Kevin Cannon, AGC's senior director, safety & health services, said the Department of Labor (DOL) and OSHA issued new guidelines on preparing workplaces for COVID-19 and recording workplace exposures to the disease. Since information and news on the disease keep evolving, OSHA has already updated this information once and may likely do it again.

Coronavirus and contracts. Brian Perlberg, senior counsel, construction law and contracts, discussed this outbreak as a "force majeure," as it is an unforeseeable event that no party controls or is at fault. He advises contractors to read back through the contract to see if it makes an adjustment for time or money. Each contract is different, and its verbiage will show what is allowed. For example, the ConsensusDocs 6.2.1(j) specifically listing epidemics as an excused delay, while AIA A201 General Conditions has a catch-all for acts beyond the contractor's control as determined by the architect.

Electrical Rooms Likely to Grow Larger

Enter your text here ...

 New 2020 NEC egress requirements around large equipment will require more space.

When designing future projects to meet the requirements of the 2020 Edition of the National Electrical Code (NEC), chances are your electrical rooms, power distribution centers, and substations will grow a bit larger. Why? There was one simple sentence added to Sec. 110.26(C)(2), which states: "…Open equipment doors shall not impede the entry to or egress from the working space…".

The electrical equipment being referred to in this Section specifically includes any piece of electrical equipment containing "overcurrent devices, switching devices, or control devices" if the equipment is either: (1) rated 1,200A or more and over 1.8 m (6 ft) wide, or (2) the service disconnecting means installed in accordance with Sec. 230.71 where the combined ampere rating is 1,200A or more and over 1.8 m (6 ft) wide.

Even though this requirement was added to Sec. 110.26 (1,000V or less) by way of Sec. 110.30, this change will apply to ALL large electrical equipment meeting the above-mentioned criteria, regardless of the voltage level. This change will most likely result in a substantial increase in the size of most rooms containing large motor control centers or switchgear.

For many years, most Authorities Having Jurisdiction (AHJs) have categorized most cases where there are two pieces of opposing equipment fronts to be a "Condition 3" situation [either NEC Table 110.26(A)(1) or Table 110.34(A)]. It will be interesting to see if AHJs will now require the requisite 24 in. egress space where opposing equipment doors can be fully opened simultaneously. This condition could occur either where the open doors are directly across from one another or at opposite ends of the working space. If the new requirement gets applied in this manner, the electrical room size could increase even more.

This rule change is new to the 2020 NEC, but it's just a matter of time before it is incorporated into OSHA 29 CFR Part 1910, Subpart S. However, in the United States and its territories, OSHA inspectors already actively enforce the NEC as part of worker safety required by the General Duty Clause 5(a)(1), which requires employers to provide safe working environments and conditions. So, the inevitable inclusion as part of 29 CFR Part 1910 is somewhat irrelevant.

An updated fault current definition and additions to NEC Article 408 help increase safety

This past summer, National Electrical Code (NEC) and National Fire Protection Association (NFPA) committee members updated fault current definitions and added new requirements related to switchboards, switchgear and panelboards in NEC Article 408. I believe the updates will make it easier for installers, designers and inspectors to ensure this electrical equipment is applied within their rating for safer power distribution systems.

The changes
New unified terminology for short-circuit current and fault current will provide clarity as these terms had been used interchangeably throughout the NEC.

In parallel, new requirements were added to NEC Article 408 to support the proper application of electrical products concerning short-circuit current rating (SCCR) and interrupting ratings of overcurrent protection devices (OCPDs).

Together, these changes are important because they reduce the likelihood of electrical hazards. The SCCR calculations and equipment labels will instrumental to informing maintenance practices and future equipment upgrades.

 The rationale for change

Definition language

The definition now states that "available fault current" is the highest short-circuit current that can flow at a particular point in the electrical system. "Maximum available short-circuit current" and "short-circuit current" were also changed to "available fault current."

Markings
Previously, the NEC did not require that switchboards, switchgear and panelboards have labeled SCCR and available fault current values. Now, Article 408.6 does.

The NEC 2020 code review reaffirmed a straightforward practice that's proven quite successful:

  • Know the SCCR of equipment and the interrupting rating of the OCPD
  • Know the available fault current
  • Compare the two, making sure the fault current is less than the rating

What might the future hold?
In my opinion, the changes offer common-sense solutions for everyday issues encountered in the field. But, as with any Code change, I expect some in our industry will have to adjust how they work over the short- and long-term.

"As with any Code change, I expect some in our industry will have to adjust how they work over the short- and long-term. "
Thomas Domitrovich, Eaton vice president, technical sales

Short term

Getting used to the Code

The new language "available fault current" in replace of "maximum available short-circuit current" may give some readers pause. I expect the adjustment period to be short because, while the language has changed, the intent remains the same.

Calculations are a must

This is a significant change due to the sheer volume of equipment that must now be marked with available fault current. I believe the new requirement will drive home the importance of performing fundamental equipment evaluations at install.

Long term

Additional labeling

The way equipment is labeled may need to be examined and changed. For instance, when a panelboard is shipped, the manufacturer often has no way of knowing what OCPDs will be placed inside. The standards for these products require that a label reflect how to determine the SCCR, not the SCCR of the panel, which is dependent upon the lowest interrupting rating of the breaker that's installed. It's up to the installer and the Authority Having Jurisdiction to determine that panelboard's overall SCCR.

Additional SCCR marking requirements for other types of equipment during installation may come to fruition. It's important to remember there are different levels of protection available. When equipment is clearly labeled with SCCR, it will help raise awareness that any replacements or additions should have a minimum interrupting rating per the marking. I believe this will help reduce the likelihood of a technician installing an insufficient breaker when adding a circuit or replacing a faulty device and will raise the awareness of the proper continued maintenance and servicing of equipment after the fact.

Designing big from the start

It's vital to remember that electrical systems change and many organizations plan to expand their facilities. And while most design engineers account for growth, on commercial projects, where the bottom line is king, builders may look to the least expensive option without accommodating the future: motor additions, transformer increases and the like. In my opinion, stepping up to the next interrupting rating is a better choice than cutting it too close. I encourage all designers and contractors to closely align with customers on a comprehensive plan for their system:

  • Designers: Work with clients to understand their growth potential over the next five to 10 years and develop plans that allow for expansion.
  • Contractors: Refrain from "value engineering" builds. Work with customers to access future growth potential and explain how slightly higher costs today can save them time and money tomorrow.

"I encourage all designers and contractors to closely align with customers on a comprehensive growth plan."
Thomas Domitrovich, Eaton vice president, technical sales

Can we define growth overages for fault current?

While the available fault current language changes and additions to Article 408 greatly enhance safe OCPD installation, I believe the NEC can do more to provide a fault current overage baseline to help all understand when to recommend increased protections. I've spoken with numerous inspectors and many feel there's an opportunity to establish effective interrupting rating requirements, perhaps by looking to the NEC's exploration of adding overage requirements for calculations as a guide.

My question to the NEC: can we establish fault overage guidelines for electrical designs? For instance, how close to 10,000 amps should designers get before bumping up to a 22,000-amp breaker? Would a 1,000-amp baseline suffice? Or 2,000 amps? Whether for NEC requirements or industry practice, a dialog regarding guidelines that help designers and contractors understand when it's appropriate to go to the next level of protection to maintain safety if and when distribution systems expand would help drive change.

As Building Infrastructures Age, Up-to-date Assessments Can Ensure High Performance and Resilience

Changes to a building that occur over time can often make building performance less efficient and less resilient. As time goes on, building use characteristics often diverge from those that were used initially to design and commission a building. A good example of this is improper outside air ventilation rates which can lead to problems with indoor air quality (IAQ), or excess operational costs. Building power and cooling infrastructure components can also wear out and fall out of calibration. As more and more powered equipment gets added, power capacities are exceeded, and unanticipated downtime issues begin to emerge.

As systems age, they decline in performance, which leads to failures that significantly impact the bottom line. A perfect example is a research facility that examines proteins and crystals in their research of bacteria and virus-borne diseases. The facility recently decided to upgrade its installed base of microscopes in response to pharmaceutical customer demand for more accuracy. Their existing building power infrastructure supported a 1-megawatt (MW) power switch, which was previously adequate as the building consumed 600 kW of power on an average day, and nosed up to 800 KW on the hottest of summer days when air conditioning systems work at full capacity.

Given the required upgrade, a cost effective, steady power supply with peaks in excess of 1MW was now required in order to accommodate stringent purity requirements and to avoid losing both data and research samples.

Our solution was to implement a lithium-ion-based energy storage solution physically located inside of the building. The battery selected for this purpose supplies stored power to the facility when demand spikes over 1MW and then recharges from the grid. This cost-effective change to the lab's existing power infrastructure successfully managed the building's increased power capacity requirements and helped the research lab remain competitive in their market.
Approaches for validating current building requirements

For organizations seeking to ensure consistent building power, cooling, and building automation performance, here are some preliminary steps that should be taken to validate requirements:

Identify common needs of both traditional and new critical infrastructure – Building owners need to periodically assess the health of different types of building critical infrastructure. This includes both generators and power distribution systems and the IT backbone – anything that keeps the building on its mission at a predictable operating cost. These infrastructure pillars need to be assessed in order to determine whether changes to the building have altered the efficiencies.
Identify needs unique to your facility – Understanding the unique requirements of the building under management also heavily impacts how technology is deployed to improve performance. Sports arenas, for instance, have a specialized need for higher dehumidification. High precision temperature control and monitoring are needed to both accommodate tens of thousands of fans and to assure that ice rink temperatures, for example, are properly maintained.

Healthcare facilities require more highly regulated environments. Circulating air has to be regularly monitored. Sophisticated backup power systems are required since connected hospitals have no real ability to shut down. In government and municipal buildings–such as prisons and K-12 public schools–a higher focus on safety and security emerges as a primary concern. Commercial buildings are focused more on comfort and lighting so that employee productivity can be maintained. Knowing the unique characteristics of your building and applying the right building automation technologies suited to those unique needs is a key performance driver.
Changing times demand more building resilience

Regardless of the type of facility, building owners also need to be aware that building resilience is emerging as a growing need. For many years, predictable building performance was taken for granted by the occupants. But now, the existing power grid has grown older. As power sources such as coal and nuclear phase out in the US, new solar and wind power are being introduced. These changes make power quality more intermittent and downtime can now occur in areas where power fluctuations were once rare. In addition, pockets of businesses continue to expand across regions driving more demand for clean, "always on" power. In these cases, building infrastructures need to be reexamined in order to withstand the demands of the "new normal."

The use of reconditioned equipment and its safety implications

"A basic understanding of the term 'reconditioned' is critical to success." ~Thomas Domitrovich, Eaton Vice President, Technical Sales
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.

 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.

NEC 2020 load calculation changes can make budgets more efficient and increase safety

 by Thomas Domitrovich, P.E., LEED AP, vice president, technical sales at Eaton

Members of the National Fire Protection Association (NFPA) recently concluded discussions on updating Article 220.12 of the NEC (National Electrical Code) to align with a series of energy codes and to account for higher-efficiency lighting solutions in commercial and healthcare buildings.

Because many of today's lighting solutions are increasingly energy efficient, lower current demands exist for power systems. These efficiencies necessitate extensive revisions to the calculation table used to determine volt-amperes (VA) per square foot. Many commercial structures today are built to specific energy code editions or a standard established by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). NEC 2020 updates now align the NEC with these energy codes, allowing for easier, more consistent installation in the field.

Not only do changes to Article 220.12 streamline industry codes and standards language, they also help design engineers create load calculations that recognize more efficient lighting loads. This, in my opinion, may result in lower infrastructure costs and help fund enhanced safety solutions.

Article 220.12's new load calculations do more to help designers get it right the first time.

Thomas Domitrovich, vice president, technical sales 

The 2020 change

Changes were made for healthcare and commercial buildings. In healthcare, the NEC's Code-making Panel 2 (CMP2) removed demand factors from the lighting load calculation. Hospitals are drastically different from the large facilities that were common 40 years ago. Today, the healthcare industry looks to smaller surgical and outpatient facilities, which require a different approach to lighting load calculations. In addition, CMP2 lacked the data from ASHRAE and other organizations needed to validate regulations reducing hospital lighting to 32 percent. Without the data required to permit the reduction, the derating values for hospital lighting were deleted.

In commercial buildings, VA per square foot values were reduced (with some exceptions) to align with occupancy energy codes. Examples of VA per square foot changes include banks from 3.2 to 1.3; hotels and motels from 2 to 1.7; garages from .5 to .3; hospitals from 2 to 1.6; courthouses from 2 to 1.4. Armories and auditoriums were raised from 1 to 1.7.

Also, commercial occupancies now align with those set by ASHRAE. The calculation table includes footnotes that help NEC users understand the change in occupancy-type designations and clarify older vs. newer occupancy types and language translations. Here are some designation examples:

  • Armories and auditoriums, considered gymnasium-type occupancies
  • Lodge rooms, considered similar to hotels and motels
  • Industrial commercial loft buildings, considered manufacturing-type occupancies
  • Banks, considered office-type occupancies
  • Garages and commercial storage, considered parking garage occupancies
  • Clubs, considered restaurant occupancies
  • Barbershops and beauty parlors, considered retail occupancies
  • Stores, considered retail occupancies

The rationale for change


While Article 220.12 has changed little since its NEC adoption in 1971, technology and sustainability initiatives have greatly advanced. Because of energy-efficient technologies for structures, LEED and other energy conservation efforts and energy codes and standards updates, the NEC needed to create parity.

Industry chatter regarding the size of service entrance equipment in relation to actual load, transformers and the like has been heard for at least the last two code cycles. Industry professionals realized that energy-efficient technologies had advanced to a point where load calculations were suspect of being grossly overestimated. Some in the industry claimed load calculation results no longer represented what happens in real-world applications thanks to technologies that use less energy, such as LED lights, fluorescents, high-efficiency transformers and variable frequency drives. Lower energy footprints impact the load calculations used to determine branch circuit size, feeders and everything else associated with power delivery, thus prompting the NEC to make changes that better ensure safety.

The basis of ASHRAE alignment

When many structures are built, ASHRAE requirements adopted by a state or local jurisdiction dictate VA per square foot, and builders may not exceed those requirements. However, CMP2 understood that not every jurisdiction adopts the latest ASHRAE standard. Some states use older ASHRAE requirements, and some jurisdictions don't adopt the requirements at all. This played a factor in the language included in the NEC.

Lower VA per square foot values influence smaller feeder and service sizes, which, if incorrect, could be very expensive to fix after the fact. NFPA members looked at different types of buildings and ASHRAE research data. The task force associated with this effort plotted VA curves for buildings of various sizes. To gain consensus and achieve change, the NEC lowered the VA values somewhat to account for those jurisdictions that do not adopt the latest version of ASHRAE standards or other energy codes. A compromise was reached in using the 2000 version of ASHRAE 90.1 as the uniform reference for VA values.

Financial impacts and safety implications

Some industry professionals reported that, when placing an ammeter on a structure's service conductors, load currents showed a considerable margin between capacity and actual usage. Facilities typically consume less power due to higher-efficiency lighting equipment that's installed and conservative factors that design engineers may use to ensure future capacity for growth. (Energy-efficient solutions are not required by the Code but are installed because of the energy savings they offer.)

I believe it's important to include right-sized services in structures that meet design goals driven by customer wants and needs. The Code changes will offer financial relief for electrical infrastructures by foregoing equipment that's not needed—but the design engineer must always keep a close eye on the needs of the customer. The changes help the design engineer reduce the size of electrical distribution equipment where permitted by the design goals. This could translate into less wire and other related gear. With that, I hope a focus on providing safety technologies for our electrical workers will grow. Funding originally intended for power distribution can be reallocated to safety solutions for branch, feeder and service entrance equipment.

A thought on using the Code as a design guide

NEC Article 90 states that the Code should not be used as a design reference. Language in Article 220.12 exemplifies why. As mentioned, there's an informational note attached to 220.12. It states, "The unit values of Table 220.12 are based on minimum load conditions and 100 percent power factor and may not provide sufficient capacity for the installation contemplated." In essence, this means guidelines may not be sufficient for an installation. So, while the installation may be safe, it may not turn on because there isn't enough power to serve the load.

In my opinion, designers must focus on customer wants and create load calculations based on a distribution system's current and future needs. Many designers look to the Code before creating their designs, but they should do the opposite. I encourage all planners to meet customer wants and needs first and then check their designs against the Code to assure alignment.

Designers must focus on customer wants and create load calculations based on a distribution system's current and future needs.

Thomas Domitrovich, vice president, technical sales 

What might the future hold?

While financial efficiencies and safety improvements were made, the NEC looks to do more to influence load calculations in healthcare environments and commercial structures.

Healthcare

Healthcare representatives believe load calculations are often high because, in an operating room, for example, many receptacles are installed. This makes sense—doctors never want to be without power options when lives hang in the balance. But the additional receptacles cause excessive infrastructure sizing. And practically speaking, many receptacles aren't used. The NEC is currently researching what, if anything, can be done to improve receptacle load calculations for hospitals and other occupancy types, such as clinics, medical offices and ambulatory care centers.

Commercial structures

A task group launched a research project in collaboration with the NFPA Research Foundation. The team is actively measuring the energy usage on receptacles in a variety of commercial buildings to determine if additional load calculation recommendations are an option. I believe the task group's report will heavily influence the public input phase for the 2023 code review.

Better calculations improve efficiency and safety

It's essential to strike a balance when calculating VA. If load calculations are too low, designers may likely plan for and install insufficient equipment, resulting in a situation that's expensive to fix after the fact. If load calculations are too high, it's possible to overpay for equipment that's not needed. I believe Article 220.12's new load calculations do more to help designers get it right the first time. The changes will help designers save money, which will hopefully inspire their clients to reallocate funds for the safety devices used to reduce maintenance on energized equipment in the field.
