The NACHI inspector who sent me this photo noted that there was no cover to be found for this panelboard. The integrity of electrical equipment and connections must be maintained. Internal parts of electrical equipment, including busbars, wiring terminals, insulators, and other surfaces, can't remain in operation when they're damaged or contaminated by foreign materials like paint, plaster, cleaners, abrasives, or corrosive residues. Never permit damaged parts, such as those that are broken, bent, cut, or deteriorated by corrosion, chemical action, or overheating, that may adversely affect safe operation or mechanical strength of the equipment to remain in operation. See the requirements of 110.12(C).
