Answer:
Hint: The inside of this service equipment appears a little speckled, wouldn’t you agree?
Even though the cover was nearby, this is a perfect example of a major violation of 110.12(C), Integrity of Electrical Equipment and Connections. This Code requirement states, “Internal parts of electrical equipment, including busbars, wiring terminals, insulators, and other surfaces, cannot be damaged or contaminated by foreign materials such as paint, plaster, cleaners, abrasives, or corrosive residues. There shall be no damaged parts that may adversely affect safe operation or mechanical strength of the equipment such as parts that are broken; bent; cut; or deteriorated by corrosion, chemical action, or overheating.”
