Description
NFPA 70B: Standard for Electrical Equipment Maintenance, 2023 edition
NFPA 70B 2023 edition sets structured requirements for maintaining electrical, electronic and communication systems in a safe and reliable manner. This edition marks a major change: NFPA 70B is now issued as a formal standard, with mandatory maintenance requirements in place of the earlier optional guidance.
The standard covers the development and running of electrical preventive maintenance (EPM) programs across industrial, commercial, institutional and large residential facilities. It focuses on reducing equipment failure, cutting unplanned downtime and supporting personnel safety through systematic inspection, testing and maintenance.
This listing is the 2023 edition. NFPA has since published a 2026 edition, so check which year your contract, insurer or inspector cites before you order. Choose this book if your requirement names NFPA 70B 2023.
What the standard now requires
Because NFPA 70B moved from a recommended practice to a formal standard, its maintenance requirements are mandatory rather than optional. It covers planning and documentation, equipment condition assessment, testing methods, system studies, power quality, grounding and ground fault protection.
Maintaining specific equipment and long shutdowns
The standard gives detailed guidance for maintaining specific types of electrical equipment, assemblies, cables and devices, including equipment subject to extended shutdown intervals.
Working alongside NFPA 70E
NFPA 70B is designed to be used together with NFPA 70E, so organizations can align electrical maintenance activities with workplace electrical safety practices.
