What is the National Electrical Code (NEC)?
The National Electrical Code (NEC), or NFPA 70, is a United States standard for the safe installation of electrical wiring and equipment. It is part of the National Fire Codes series published by the National Fire Protection Association (NFPA). “National Electrical Code” and “NEC” are registered trademarks of the NFPA. While the NEC is not itself a U.S. law, NEC use is commonly mandated by state or local law, as well as in many jurisdictions outside of the United States. The NEC codifies the requirements for safe electrical installations into a single, standardized source. The “Authority Having Jurisdiction” inspects for compliance with these minimum standards, such as a professional from the International Association of Electrical Inspectors (IAEI).
