Which action is listed as part of electrical maintenance?

• A. Infrared scans
• B. Replace circuit breakers
• C. Test smoke detectors
• D. Perform oil change

Answer: (A)

Infrared scans are a key part of electrical maintenance because they use a thermal camera to spot abnormal heat in energized electrical gear. Hot spots can indicate loose connections, overloaded circuits, aging components, or insulation problems. Detecting these issues early lets you target maintenance—tightening connections, replacing worn parts, or rerouting loads—before a failure or fire occurs. The other options aren’t typically considered routine electrical maintenance: replacing circuit breakers is a repair action based on fault or wear, testing smoke detectors is more about building safety systems than electrical upkeep, and an oil change is mechanical maintenance for motors or compressors, not the electrical distribution itself.
