National Electrical Code® Adoption Update

NEC Adoption Map 9-21Adoption of the latest edition of the NEC® appears to be gaining momentum and it’s no surprise. The latest edition of the Code contains important requirements related to installations such as energy storage systems, energy management systems, microgrids, large-scale photovoltaic systems and more. Development of the NEC has been largely focused on keeping the content relevant so it remains practical, enforceable and adoptable by inspection jurisdictions.

Adoption maps are available and useful to electrical contractors working across jurisdictional lines. The relevancy relates primarily to licensing and project permitting.
