Which standard specifically covers electrical equipment preventive maintenance?

• A. NFPA 70E
• B. NFPA 70
• C. IEC 60364
• D. NFPA 70B

Answer: (D)

Preventive maintenance of electrical equipment is guided by a standard that lays out the recommended practices for maintaining such equipment, including when and how to inspect, test, lubricate, clean, and monitor condition, plus how to document results. This standard is designed to help establish and follow a maintenance program that keeps equipment reliable and safe, reducing unexpected outages. The other standards serve different purposes: NFPA 70E focuses on electrical safety for workers—safe work practices, PPE, and arc-flash risk—rather than maintenance procedures. NFPA 70 (the NEC) covers installation, wiring methods, and equipment ratings for electrical systems, not maintenance programs. IEC 60364 addresses the design and installation of electrical installations in buildings and related compliance, not specifically the preventive maintenance of equipment. Therefore, the standard that specifically covers electrical equipment preventive maintenance is NFPA 70B.
