Complete guide on the NFPA 70B standard and how to stay compliant

What is NFPA 70B?

NFPA 70B is the Standard for Electrical Equipment Maintenance. It outlines how electrical systems should be inspected, tested, and serviced to maintain a safe condition. The standard defines what a documented electrical maintenance program must include and reinforces the connection between equipment maintenance, worker protection, and system reliability.

How NFPA 70B Has Evolved

Before 2023, NFPA 70B operated as a recommended practice. Today it is an enforceable standard. This shift—from “should” to “shall”—gives regulatory authorities, insurance carriers, and facility owners a clearer basis for evaluating maintenance programs.

What’s New in NFPA 70B

Four key changes in the 2026 edition of NFPA 70B:

An expanded scope that includes predictive and corrective maintenance
Maintenance‑related design that eliminates or reduces hazards during maintenance tasks
Stronger alignment with NFPA 70E around hazard elimination and exposure reduction
Inclusion of operational technology cybersecurity in the EPM to address vulnerabilities in digital systems

When the standard changes, so does your maintenance strategy

NFPA 70B 2026 introduces mandatory requirements where recommendations once existed, shifting how organizations plan, assess, and sustain their electrical maintenance programs. This white paper examines what's changing and what it means for your operations: predictive maintenance requirements, risk-based decision-making, equipment condition assessment, and strategies for building a long-term program that keeps pace with the updated standard.
