Product Description
The NFPA 70B, Standard for Electrical Equipment Maintenance, 2023 Edition is the authoritative standard for the maintenance of electrical systems and equipment in commercial, industrial, and institutional facilities. The 2023 edition marks a significant transformation of NFPA 70B — transitioning from a recommended practice to a mandatory standard — making it more critical than ever for facility managers, electrical maintenance professionals, and AHJs responsible for electrical system reliability and safety.
This landmark 2023 edition establishes minimum mandatory requirements for electrical preventive maintenance (EPM) programs, helping organizations reduce electrical failures, prevent arc flash incidents, and ensure the long-term reliability of their electrical infrastructure.
- Complete 2023 edition — now a mandatory standard (previously a recommended practice)
- Covers electrical preventive maintenance (EPM) program requirements and documentation
- Addresses switchgear, transformers, motors, generators, and wiring systems maintenance
- Includes thermographic (infrared) inspection, power quality analysis, and testing requirements
- Covers arc flash hazard reduction through proper maintenance practices
- Addresses maintenance intervals, condition-based maintenance, and risk-based approaches
- Includes recordkeeping, labeling, and maintenance documentation requirements
- Essential for facility managers, electrical maintenance technicians, engineers, and AHJs
Proper electrical equipment maintenance is the foundation of a safe, reliable, and efficient electrical system. NFPA 70B (2023) gives facilities the mandatory framework they need to implement effective electrical preventive maintenance programs that reduce downtime, prevent failures, and protect personnel from electrical hazards.
