NEC Requirements for Information Technology Equipment

Article 645 of the 2017 Edition of the National Electrical Code (NEC) covers equipment, power supply wiring, equipment interconnecting wiring, and grounding (bonding) of information technology (IT) equipment and systems in IT equipment rooms.

Many other areas in the NEC apply to these rooms [Sec. 645.3(A) through (I)]. For example, the non-current-carrying conductive members of optical fiber cables within such a room must be bonded per Sec. 770.14 [645.3(C)]. And you'll find sections of half a dozen other Articles referenced in Sec. 645.3(B)(1) through (6).

You can use Art. 645's wiring methods instead of the wiring methods of Chapter 3 and Parts I and V of Art. 770, but only if you meet the conditions listed in Sec. 645.4(1) through (6).

Branch circuits supplying one or more units of IT equipment must have an ampacity of at least 125% of the total connected loads. If you run branch circuit supply conductors under a raised floor, you must install them per the requirements in Sec. 300.11. You must also use the wiring methods of Sec. 300.22(C) and/or the 17 wiring methods listed in Sec. 645.5(E)(1)(b)(1) through (17).

OCPDs supplying critical systems must be selectively coordinated [645.27] with all supply side OCPDs.

NFPA 70E vs OSHA

You already have OSHA, so why also follow NFPA 70E? And if NFPA 70E can actually make you safer, why don't the OSHA regulations include it?

The OSHA regulations govern the employer. Their main thrust is to ensure the employer has a safety program that meets specific standards of performance and the employer properly trains the employees to conform with that program.

NFPA 70E helps employers and employees provide a practical safe working area relative to the hazards arising from the use of electricity.

So OSHA and NFPA 70E work together. Not only that, key OSHA personnel have been involved in the development of NFPA 70E for quite some time. They have worked directly with electrical industry leaders, including executives of electrical service firms.

It's not an either/or choice. The employer is legally obligated to conform to OSHA regulations. But is the employer obligated to use NFPA 70E? In a practical sense, yes. When the employer and employees utilize NFPA 70E, they reduce hazards not only to employees but to the companies they work for. The financial, operational, and emotional impact on a firm when an employee suffers an arc blast or electrocution can be severe.

NFPA 70E is a practical guide. But don't forget the value of a safety culture. This must be nurtured from the top down and from the bottom up. When everyone is thinking of how to identify hazards and protect workers from them, the way people use NFPA 70E will be far more effective than if they are trying to see what they can get by with or counting on luck (which tends to run out sooner or later).

Eaton to Spin Off Lighting

The move will create a stand-alone powerhouse in luminaires and controls. 


Eaton Corp., Dublin, Ireland, said it intends to pursue a tax-free spin-off of its Lighting business. The spin-off will create an independent, publicly traded company and is expected to be completed by the end of 2019. Goldman Sachs is serving as Eaton's financial advisor on the transaction.

The move will create a stand-alone powerhouse in luminaires and controls with a package of brands mostly built by Cooper Lighting, which Eaton acquired in 2012, including Halo, Metalux, McGraw-Edison, Neo-Ray, Lumiere, Lumark, Pauluhn, Corelite, Ephesus and AtLite.

In a letter this morning to customers and channel partners, Eaton Lighting President Kraig Kasler and VP Sales Joe Melchiors said the Crouse-Hinds Industrial Lighting business and the Life Safety division's emergency lighting product lines in Europe, the Middle East and Africa will remain with Eaton.

The Eaton Lighting business had sales of $1.7 billion in 2018, serving customers in commercial, industrial, residential and municipal markets.
