Maintenance in NFPA 70E is intended for preserving or restoring the condition of electrical power systems equipment or devices for ? . Electrical safety is directly tied to the ? of electrical power systems equipment.

• A. The Reliability of the Power Supply
• B. The Safety of Employees Exposed to Electrical Hazards; Condition of Maintenance
• C. Cost Efficiency of Maintenance
• D. Performance of Non-Electrical Systems

Answer: (B)

Maintenance in NFPA 70E is about keeping electrical equipment in a safe condition to protect people. The idea is that the safety of employees exposed to electrical hazards is directly tied to how well the equipment is maintained—their risk depends on the equipment’s insulation, grounding, protective devices, labeling, and overall condition. When maintenance preserves or restores this safe state, the potential for shocks, arc flash, or equipment failures is reduced. The other options shift focus to reliability, cost, or non-electrical systems, which aren’t the primary aim of NFPA 70E maintenance in the context of worker safety.
