SpecLink Addresses 2014 NEC Changes 

By Joe I. Moreland, PE, CSI (GA PE#26321)

As part of BSD's strict policy to keep Referenced Standards up to date, a thorough evaluation of the new 2014 edition of the National Electrical Code (NFPA 70) was performed. The following changes led us to issue SpecLink updates so that your specifications will be ready when jurisdictions begin adopting this new edition:

  • NEC 200.4(B)
    • Summary of Change:  Neutral/grounded conductors for multiple circuits are now required to be grouped or otherwise identified with associated ungrounded conductors in enclosures.
    • SpecLink Section(s) Affected:  26 0519 - Low-Voltage Electrical Power Conductors and Cables (execution requirement added).
  • NEC 406.3(E)
    • Summary of Change:  A new marking symbol (illustrated in the code) is now required for receptacles controlled by an automatic control device or by an automatic energy management system.
    • SpecLink Section(s) Affected:  26 2726 - Wiring Devices (product added).
  • NEC 406.9(B)(1)
    • Summary of Change:  Weatherproof receptacle covers for wet locations are now required to be identified as "extra-duty" type. Previously this was only required for boxes supported from grade.
    • SpecLink Section(s) Affected:  262726 - Wiring Devices (product revised).
  • NEC 517.30(E)
    • Summary of Change:  Health care facility receptacles served from the essential electrical system must now have an illuminated face or indicator light to indicate that there is power to the receptacle.
    • SpecLink Section(s) Affected:  26 2726 - Wiring Devices (product added).
  • NEC 690.12 & 690.56
    • Summary of Change:  Rapid shutdown capability is now required for photovoltaic systems on buildings, along with associated identification.
    • SpecLink Section(s) Affected:  26 3100 - Photovoltaic Collectors (execution requirement added/revised).

Other Notable Changes

The following is a sampling of other changes that did not directly affect SpecLink but may be of interest to you:

  • NEC 110.26(C)(3)

    • Panic hardware is now required on electrical rooms with equipment rated 800 amps or more (the threshold was previously1200 amps). The requirements of 110.26(C)(2) still apply to 1200 amps or more.
  • NEC 110.26(E)(2)

    • Dedicated equipment space requirements have been clarified to apply to outdoor installations. This makes it clearer that no downspouts, piping, etc. are to be routed on exterior walls above electrical equipment.
  • NEC 210.64

    • A receptacle is now required to be installed within 50 feet of electrical service area. This distance seems to be quite liberal will likely be met with receptacles in or near the electrical room/area anyway. However, receptacles will likely need to be added for electrical service equipment mounted on the exterior of the building.
  • NEC 250.102(C)

    • There is a new table for bonding conductors.
  • NEC 376.56(B)

    • Power distribution blocks in wireways that are on the line side of the service equipment must now be listed for that use, and they must be unobstructed after installation.
  • NEC 422.5

    • GFCI devices protecting appliances (e.g. vending machines, electric drinking fountains) must now be readily accessible.
  • NEC 450.10

    • The grounding and bonding terminal bar in a transformer now cannot be mounted on or over vented openings.
  • NEC 600.6 (A)(1)

    • Disconnects for signs must now be located at the point where the circuit enters the sign enclosure or associated pole.
  • NEC 700.19

    • Multi-wire branch circuits now cannot serve emergency lighting.
  • NEC Article 750

    • This new article covers Energy Management Systems.
  • NEC Annex J

    • This new annex summarizes requirements of ADA applicable to electrical work.

Of course there are many changes not listed here. A publication like NFPA's "Analysis of Changes" series can be a useful tool for sorting through the changes to identify requirements that impact your projects.

Another useful tool, often overlooked, is SpecLink's master note content. There are many references to specific portions of the NEC to point you toward requirements relevant to the decisions you make when writing specifications. Furthermore, when master text is added or revised as the direct result of an NEC change, the master note usually includes a summary of the new requirement, and where to find it. Consequently, it is entirely possible that the first place you will hear about a new NEC requirement is through your SpecLink subscription.
