NFPA 70B: Standard for Electrical Equipment Maintenance, 2026 Edition

NFPA 70B stopped being a recommended practice and became a standard, which changed what it means for a facility. Where it once suggested good habits, it now sets requirements — and that makes an electrical maintenance program an auditable obligation rather than a matter of judgement.

What the standard covers

• Establishing and documenting an Electrical Maintenance Program (EMP)
• Equipment condition assessment and how it drives maintenance intervals
• Inspection, testing and servicing frequencies by equipment type and criticality
• Transformers, switchgear, circuit breakers, cables, motors and controls
• Testing methods, acceptance criteria, and record-keeping
• How 70B interlocks with NFPA 70E arc flash requirements and OSHA expectations

Who it’s for

Facility and plant maintenance managers, reliability engineers, electrical contractors servicing commercial and industrial sites, and safety professionals responsible for demonstrating a compliant maintenance program.
