Which activity is representative of preventive maintenance for electrical systems?

• A. Replacing components after failure
• B. Waiting for equipment to overheat
• C. Examining electrical connections and wiring for damage
• D. Ignoring minor issues

Answer: (C)

Preventive maintenance means doing regular checks and servicing to catch potential problems before they cause failures. Examining electrical connections and wiring for damage fits this approach because it involves routine inspection to spot loose connections, damaged insulation, corrosion, or wear. Detecting and addressing these issues early allows tightening, cleaning, repairing, or replacing components before a fault develops, improving safety and reliability and reducing downtime. Replacing components after failure is reactive, waiting for overheating signals problems that preventive checks should catch sooner, and ignoring minor issues leads to bigger hazards.
