2023 NFPA 70B Standard for Electrical Equipment Maintenance

NFPA 70B, Standard for Electrical Equipment Maintenance 2023 edition establishes mandatory requirements for the preventive maintenance of electrical, electronic, and communication systems and equipment in industrial plants, institutional and commercial buildings, and large multifamily residential complexes. This reference provides the framework for developing and implementing an effective Electrical Maintenance Program (EMP) that reduces equipment failures, prevents employee incidents, and establishes the condition of maintenance required when assessing risk in accordance with NFPA 70E, Standard for Electrical Safety in the Workplace.

Who Uses NFPA 70B

The 2023 edition is the standard of reference for electrical engineers, facility managers, maintenance supervisors, safety officers, and electrical contractors responsible for the ongoing maintenance and inspection of electrical systems and equipment in commercial, industrial, and institutional facilities.

What's New in the 2023 Edition

The most significant change in the 2023 edition is the conversion of NFPA 70B from a recommended practice to a mandatory standard. Requirements previously written as recommendations have been updated to mandatory language throughout the document, giving the standard enforceable weight for the first time.

The 2023 edition addresses the full scope of electrical equipment maintenance, including:

• Planning and implementation of electrical preventive maintenance programs for all equipment types and assemblies.
• Development of installation specifications that incorporate maintenance requirements from the outset.
• Personnel safety requirements for maintenance activities.
• Fundamentals of electrical equipment maintenance and system studies.
