NFPA 70®: National Electrical Code® (NEC®) is the basis for electrical safety that has saved countless lives.
Adopted in all 50 states, the NEC helps protect people and property from electrical hazards involving wiring and equipment. Comprehensive provisions address electrical installations in virtually all buildings -- including commercial, residential, and industrial occupancies. Revisions to the NEC are industry-driven, based on public proposals and comments. Each edition of the Code builds on the next, through consensus-based changes that reflect the evolving needs of the field, emerging technologies, and new information about electrical safety.
