NECA Standing Policy 3 recommends adoption of the latest National Electrical Code®
edition in the interest of public and building safety.
Mike Johnston, NECA executive director standards and safety, stresses the importance of adoption because, "The latest editions include requirements related to new technology like: energy storage, large scale PV, microgrids, energy management, wireless EV charging, and power over ethernet (POE)."
"Jurisdictions that choose not to adopt the latest edition will be challenged when handling systems of these technologies. Serious consideration should be given relative to delayed NEC adoption. These are only a few of the reasons that justify a swift adoption and immediate use of the latest NEC."
Where is the National Electrical Code® in effect?
As of February 1, 2018, according to the NFPA, the 2017 NEC is in effect in 19 states, the 2014 NEC is in effect in 20 states, the 2011 NEC is in effect in 3 states, and the 2008 NEC is in effect in 5 states. If you have a question on the status of NEC adoption in any state, please contact your NFPA Regional Electrical Code Specialist.
