Visual inspection
Confirm 30-mA ground-fault device (proper rating/function)
Visual inspection inside connection boxes for overheating, corrosion,
moisture, and other problems.
Proper electrical connection, ground, and bus wires insulated over
full length
Damaged or missing thermal insulation; damaged, missing, cracked
lagging or weatherproofing.
Covered end seals, splices, and tees properly labeled on insulation.
Check controllers for moisture, corrosion, setpoint, switch operation.
