NFPA 70, also known as the National Electrical Code (NEC), is a set of standards for electrical safety in the United States. It is published by the National Fire Protection Association and aims to minimize the risks of electrical hazards, ensuring safe installation and maintenance of electrical systems. The code is updated every three years to reflect new technologies and safety practices. It covers various aspects of electrical work, including wiring methods, equipment installation, and grounding requirements. Compliance with NFPA 70 is often required by local building codes to ensure the safety of electrical systems in residential, commercial, and industrial settings.
