National Electrical Code 2014 (NEC2014)

National Electrical Code 2014


The National Electrical Code (NEC), or NFPA 70, is a U.S. standard for the safe installation of electrical wiring and equipment. While the NEC is not itself a U.S. law, its use is commonly mandated by federal, state or local law. First published in 1897, the NEC is updated and published every three years. The “authority having jurisdiction” inspects for compliance with these minimum standards, although some jurisdictions do not immediately adopt new editions. OSHA 29 CFR 1910.302-.308 and .399 mandates compliance with portions of the NEC. A thorough understanding of this standard is the foundation for safe and compliant construction of electrical systems.

The NEC covers the installation of electrical conductors, equipment, and raceways; signaling and communications conductors, equipment, and raceways; and optical fiber cables and raceways for the following:

  • Public and private premises, including buildings, structures, mobile homes, recreational vehicles and floating buildings
  • Yards, lots, parking lots, carnivals and industrial substations
  • Installations of conductors and equipment that connect to the supply of electricity
  • Installations used by the electric utility, such as office buildings, warehouses, garages, machine shops and recreational buildings that are not an integral part of a generating plant, substation or control center
