What regulations govern grounding and bonding practices in electrical installations?

The National Electrical Code (NEC) is the primary standard that governs grounding and bonding practices in electrical installations in the United States. It provides detailed requirements that ensure safety by minimizing the risk of electric shock and fire hazards associated with improper grounding and bonding.

The NEC is updated regularly to reflect advances in technology and safety practices, establishing guidelines that electricians must follow to ensure that electrical systems are safely grounded and bonded. This code addresses various aspects of grounding and bonding, including the types of conductors to be used, grounding electrode systems, and the protection of equipment and personnel from electrical faults.

By adhering to the NEC, electricians and engineers can ensure compliance with nationally recognized safety standards, helping to protect lives and property from electrical hazards. The other codes mentioned may have relevance in certain contexts or regions, but the NEC is the most widely recognized authority for grounding and bonding practices in electrical installations across the United States.
