Description

NFPA 70: National Electrical Code (NEC), 2020 Edition (ISBN 9781455922970) is the authoritative electrical safety code developed and published by the National Fire Protection Association (NFPA). The NEC establishes minimum requirements for the safe installation of electrical wiring and equipment in structures and premises across the United States. Widely adopted — often by reference in local and state building codes — the NEC helps protect people and property from electrical hazards including shock and fire.

The 2020 edition reflects comprehensive revisions to address emerging technologies and evolving industry practices. These revisions include reorganized and clarified sections, enhanced grounding and bonding requirements, expanded guidance for photovoltaic (solar) systems, energy storage systems, and electrical vehicle charging infrastructure, as well as updates to wiring methods, overcurrent protection, and other critical safety provisions. The NEC is structured into chapters covering general requirements, wiring methods and materials, equipment for general use, special occupancies and conditions, communications systems, and essential tables and annexes.

Professionals such as electrical contractors, engineers, designers, inspectors, and code officials rely on the NEC for up-to-date safety standards that inform installations and inspections. Because it is periodically updated based on public input and technical expert review, the NEC remains a foundational electrical safety reference in the industry.

As a licensed electrician, I need to have the most recent edition of the National Electrical Code available for reference. The volume I received was of good quality and fulfilled my requirements.
