Which standard addresses equipment grounding?

The standard that specifically addresses equipment grounding is NFPA 70, also known as the National Electrical Code (NEC). This code provides comprehensive guidelines and regulations concerning the safe installation of electrical wiring and equipment, including detailed requirements for grounding and bonding practices. Proper grounding is essential for ensuring safety by reducing the risk of electrical shock, minimizing equipment damage, and preventing electrical fires.

While the NEC is updated periodically, including the 2021 version mentioned, NFPA 70 is the general designation for this standard and encompasses grounding requirements across all its editions. Therefore, it is fundamentally recognized in the electrical industry as the authoritative source on these practices.

The other standards listed either do not focus specifically on grounding or address different topics entirely. NFPA 60 pertains to the storage and handling of liquefied natural gas, IEEE 1000 is a foundational standard related to electrical engineering terminology, and while relevant to various aspects of electrical safety, they do not directly specify equipment grounding practices as comprehensively as NFPA 70 does.
