What is the accepted standard in the United States for safely installing and maintaining electrical systems and equipment?

The National Electrical Code (NEC) is considered the accepted standard in the United States for the safe installation and maintenance of electrical systems and equipment. The NEC provides comprehensive guidelines that cover various aspects of electrical installations, including wiring methods, equipment specifications, grounding and bonding requirements, and safety protocols.

The primary objective of the NEC is to minimize the risk of electrical hazards, such as fires and electrocution, by ensuring that electrical installations are performed in accordance with established safety practices. Compliance with the NEC is often mandated by law and adopted by local jurisdictions, which adds an additional layer of authority and relevance to its guidelines.

While organizations like OSHA, NFPA, and IEEE play important roles in the broader context of safety, fire protection, and electrical engineering, respectively, the NEC specifically addresses electrical installations and maintenance standards, making it the most applicable choice in this context.
