The National Electrical Code® (NEC) is the most widely adopted Code in the world. Approved by the American National Standards Institute (ANSI), the NEC is the most complete set of electrical Code requirements that govern electrical installations in the interest of safety for persons and property. Knowledge of the NEC is an inherent part of doing business in the electrical industry.

The National Fire Protection Association (NFPA) has been the sponsor of the NEC since 1911. Compliance with the NEC rules results in electrical installations and systems that are essentially free from hazards. 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 understand how necessary it is to maintain proficiency in the NEC rules. It is an inherent part of doing business in the electrical industry. The National Electrical Contractors Association (NECA) was the first active participant in the NEC development process as the voice of the electrical contractor. NECA has been involved since the early 1900s and continues to be active today with representation on each NEC technical committee. With over 100 years of support in the NEC development process, NECA continues to be recognized as the leading voice of electrical contractors in the development of codes and standards.
