NFPA 70B: Standard for Electrical Equipment Maintenance, 2023 edition


Access the latest requirements for safe and effective electrical system maintenance to help protect your business, facility, and personnel.

NFPA® 70B, Standard for Electrical Equipment Maintenance, details preventive maintenance for electrical, electronic, and communication systems and equipment in industrial, institutional, commercial, and large residential buildings. Used in conjunction with NFPA 70E®, Standard for Electrical Safety in the Workplace®, the document provides requirements for helping to safeguard workers, avoid equipment downtime, and reduce the cost of repairs.
