The National Electrical Code (NEC) is developed by the National Fire Protection Association (NFPA)
The National Electrical Code (NEC), also known as NFPA 70, is a set of guidelines for the safe installation of electrical wiring and equipment in the United States. While it is not a federal law, the NEC is widely recognised as the standard for electrical safety, and compliance with its rules ensures that occupancies are safe from potential electrical hazards.
The NEC is developed and published by the National Fire Protection Association (NFPA), which has sponsored the code since 1911. The NFPA's Committee on the National Electrical Code consists of 19 to 20 code-making panels and a technical correlating committee. The NEC is updated and published by the NFPA every three years, with the latest edition released in 2023.
The NEC is approved as an American national standard by the American National Standards Institute (ANSI). It is the most widely adopted code in the world, and compliance with its rules is essential for anyone working in the electrical industry. Electrical contractors must maintain proficiency in the NEC rules, and licensed electricians spend years studying and practicing the requirements before obtaining their license.
The NEC covers a wide range of topics, including the installation of electrical conductors, equipment, and raceways; signaling and communications conductors; and optical fiber cables. It applies to public and private premises, yards, parking lots, industrial substations, and installations used by electric utilities.
In addition to the code itself, the NFPA also publishes an NEC Handbook for each new edition, which includes illustrations, explanations, and cross-references to aid in understanding and applying the code requirements.

The NEC is not a US law, but its use is often mandated by state or local laws and in jurisdictions outside the US. It is part of the National Fire Codes series published by the National Fire Protection Association (NFPA) and developed by the Committee on the National Electrical Code, consisting of code-making panels and a technical correlating committee.
The NEC is formally identified as ANSI/NFPA 70, reflecting its approval by ANSI and its publication by the NFPA. The NFPA has sponsored the development and publication of the NEC since 1911, ensuring its regular updates and widespread adoption. The NEC is updated and published by the NFPA every three years, with the latest edition released in 2023.
Compliance with the NEC is essential for electrical contractors and professionals in the industry. It is also in the interest of cities and jurisdictions to adopt the NEC as their standard set of electrical requirements to ensure safety and avoid lawsuits. The NEC's widespread adoption and recognition as the minimum standard for electrical safety make it an essential framework for anyone working with electricity.

The NEC is updated and published every three years
The National Electrical Code (NEC), first published in 1897, is updated and published every three years. The 2023 edition is the most recent update. The NEC is a set of rules that must be followed for compliance and assurance that occupancies are safe from potential electrical hazards. It is the most widely adopted code in the world and is approved by the American National Standards Institute (ANSI).
The NEC is developed by the National Fire Protection Association's (NFPA) Committee on the National Electrical Code, which consists of 19 to 20 code-making panels and a technical correlating committee. The NFPA has sponsored the NEC since 1911. The NEC is part of the National Fire Codes series published by the NFPA.
While the NEC is not itself a U.S. law, its 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. Compliance with the NEC rules results in electrical installations and systems that are essentially free from hazards.
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 various structures, including buildings, mobile homes, and recreational vehicles. It also covers installations used by electric utilities, such as office buildings, warehouses, and garages, that are not an integral part of a generating plant, substation, or control center.
The NFPA also publishes a comprehensive NEC Handbook for each new edition, which contains additional illustrations, explanations, and cross-references to the code and earlier versions.

The NEC is not a US law, but its use is commonly mandated by state or local law
The National Electrical Code (NEC) 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). The NEC is not a US law, but its use is commonly mandated by state or local law, as well as in many jurisdictions outside of the United States.
The NEC is the most widely adopted code in the world. It is approved by the American National Standards Institute (ANSI) and is the most complete set of electrical code requirements that govern electrical installations to ensure safety for persons and property. The NEC is the minimum set of electrical rules that must be followed for compliance and assurances that occupancies are safe from potential electrical hazards. Electrical contractors need to maintain proficiency in the NEC rules as it is an inherent part of doing business in the electrical industry.
The NEC is revised by the National Fire Protection Association's Committee on the National Electrical Code, which consists of 19 code-making panels and a technical correlating committee. The NEC is revised every three years to ensure that the code takes into account the latest in technology and safety. Following the release of a new edition, the development process continues by soliciting proposals for amendment. Anyone, including the public, may submit proposals, but they should demonstrate data-based evidence that clearly indicates a need for the revision. Panels then review all proposed revisions and comments and, through consensus, establish the rules that make up the next version of the NEC.
The NEC is available as a bound book containing approximately 1000 pages. It has been available in electronic form since the 1993 edition. It is also available as a restricted, digitized coding model that can be read online free of charge on certain computing platforms that support the restricted viewer software. However, this digital version cannot be saved, copied, or printed. The NEC is also used by most, if not all, US government departments for their own construction.
