NFPA 70: National Electrical Code (NEC), 2017 Edition
Hundreds of changes in the 2017 edition NEC® bring you up-to-code and ready to address new sources of electrical power.
Throughout the United States and around the world, NFPA 70®: National Electrical Code® (NEC) sets the foundation for electrical safety in residential, commercial, and industrial occupancies. The 2017 edition of this trusted Code presents the latest comprehensive regulations for electrical wiring, overcurrent protection, grounding, and installation of equipment. NFPA 70: NEC has been published since 1897, and a rigorous process of review keeps it up-to-date with new technologies. In fact, more than 4,000 public inputs and 1,500 comments went into the 2017 NEC alone. Hundreds of updates and five all-new articles pave the way to a safe and efficient electrical future.
Major additions reflect the continuing growth in renewable power technology. The newest NEC addresses the advancement of privately owned wind and solar power generation and distribution equipment -- including coverage of higher voltage systems that were once only the utilities' domain. The new consumer role is a major factor in energy decentralization, and expanded NEC coverage is vital for designers, engineers, contractors, and AHJs.
Other NEC revisions protect the public and workers from deadly hazards. New labeling, such as detailed arc flash hazard warning on equipment, helps workers and supervisors assess electrical risks.
