The National Electrical Code (NEC) is a set of standards for electrical wiring in the US
The National Electrical Code (NEC), or NFPA 70, is a set of standards for electrical wiring and equipment in the United States. It is not a federal law, but a regional standard that can be adopted and enforced by states and municipalities to ensure safe electrical practices. The NEC is part of the National Fire Codes series published by the National Fire Protection Association (NFPA), a private trade association. The NEC is revised every three years to incorporate new technology and safety measures, with the latest edition published in 2023.
The NEC provides guidelines for the safe installation of electrical wiring and equipment, including requirements for branch circuits, receptacles, and fixtures. It also addresses adjustments to ampacity for wires in circular raceways exposed to sunlight and provides information on hazardous locations such as explosive atmospheres. The NEC is designed to protect people and property from electrical hazards, and compliance with the NEC rules ensures that electrical installations and systems are essentially free from hazards.
While the NEC is not a federal law, it is commonly mandated by state or local law, and non-compliance can result in legal consequences. The "authority having jurisdiction" (AHJ) inspects for compliance with the standards and has the authority to deny approval even for listed and labelled products. The NEC is also used to guide local jurisdictions in creating their own laws and regulations regarding electrical standards.
The NEC is developed by the NFPA's Committee on the National Electrical Code, which consists of code-making panels and a technical correlating committee. The NEC has been in place since 1897 and has been sponsored by the NFPA since 1911. The NEC is approved as an American national standard by the American National Standards Institute (ANSI).
