Article 516 of the NEC applies to things you use every day. Walk into your kitchen for example. The metal panels of your range, dishwasher, and refrigerator all underwent finish application operations using equipment compliant with this area of the NEC. The cores of the motors in these appliances were dipped in Art. 516-compliant systems, as were the cores of the motors used in the assembly of these appliances (Photo 1 and Photo 2).
