If possible, why should an infrared scan of inner equipment be accomplished on an AC system?

• A. To detect loose connections, imbalanced circuits, damaged switches, and material defects unseen by the naked eye
• B. To measure ambient temperature around the equipment
• C. To verify the color coding of cables
• D. To assess exterior corrosion and paint condition

Answer: (A)

Infrared scanning of inner electrical equipment is valuable because it reveals heat patterns that point to problems you can’t see just by looking. Loose connections, imbalanced circuits, damaged switches, and material defects create resistance or arcing, which generates heat. An infrared camera shows these as hotspots on the equipment surface, letting you identify and address issues before they lead to failures or outages. This proactive check helps guide maintenance like tightening connections, correcting load imbalances, or replacing faulty components. Measuring ambient temperature, verifying cable color coding, or assessing exterior corrosion or paint aren’t the purpose of this scan, and they won’t reliably indicate hidden electrical problems.
