Description
NFPA 70B: Standard for Electrical Equipment Maintenance, 2023 Edition provides structured requirements for maintaining electrical, electronic, and communication systems in a safe, reliable, and consistent manner. This edition marks a significant transition, as NFPA 70B is now issued as a formal standard, establishing mandatory maintenance requirements rather than optional guidance.
The standard addresses the development and implementation of electrical preventive maintenance (EPM) programs across industrial, commercial, institutional, and large residential facilities. It focuses on reducing equipment failure, minimizing unplanned downtime, and supporting personnel safety through systematic inspection, testing, and maintenance practices.
NFPA 70B covers a broad range of maintenance considerations, including planning and documentation, equipment condition assessment, testing methods, system studies, power quality, grounding, and ground-fault protection. It also provides detailed guidance for maintaining specific types of electrical equipment, assemblies, cables, and devices, including those subject to extended shutdown intervals.
Designed to be used alongside NFPA 70E, this standard supports organizations in aligning electrical maintenance activities with workplace electrical safety practices. NFPA 70B is an essential reference for facility managers, electrical engineers, maintenance professionals, safety officers, and inspectors responsible for maintaining electrical system performance and reliability.
