nec 2017 code adoption map

The National Electrical Code has made some changes that may affect any installations made after September, 1 2017. The NEC is a federal regulation program that sets electrical safety standards for all residential, commercial, and industrial buildings. As of May 9, 2018, 20 states have adopted the 2017 NEC code regulations. Nine other states are in the process of completing the adoption process, and two states are currently in the process of adoptin  the 2014 edition(1).

*Please Note* The 2017 edition of the NEC was issued by the NFFPA Standards Council on August 4, 2016. The effective date was August 24, 2016, when it officially became available for adoption by federal, state, county, and municipal governmental entities.

HomElectrical has customers all over the United States, and each state has its own rules and regulations when it comes to electrical device installation and building code. While some of our customers are professionals in the electrical and construction industries, many are the Jack-of-all-trades and Do-It-Yourselfers. For that reason, we have created this reference guide to help you make the correct purchase of electrical devices to fit your needs, and to follow the regulations used in your area.
