NFPA 70: National Electrical Code (NEC), 2023 Edition is the authoritative safety code that establishes comprehensive minimum requirements for electrical system design, installation, and inspection. Published by the National Fire Protection Association (NFPA), this model code is developed through a rigorous consensus process and widely adopted (often with local amendments) across U.S. states and jurisdictions to safeguard people and property from electrical hazards.
The 2023 edition reflects significant updates and modernizations compared to prior editions, addressing rapidly evolving electrical technologies and industry practices. Among its improvements, the NEC 2023 reorganizes key sections for better clarity and accessibility, expands Article 100 to consolidate defined terms, and enhances requirements for wiring methods, equipment, grounding and bonding, renewable energy systems, surge protection, energy storage systems, and other special electrical applications.
Electricians, electrical engineers, designers, contractors, inspectors, and code officials rely on this edition as the foundation for designing and installing safe electrical systems in homes, workplaces, and industrial facilities. The NEC’s structured chapters — from general requirements to detailed provisions for special conditions — make it a comprehensive guide for meeting modern electrical safety standards.
