Which code does this activity belong in?
Current-Carrying Wiring Device Manufacturing comprises establishments that produce devices designed to carry electrical current through circuits, such as switches, receptacles, lamp holders, bus bars, and lightning arrestors. The distinguishing boundary separates these active current-conducting components from Noncurrent-Carrying Wiring Device Manufacturing, which produces the passive structural and protective elements like electrical boxes, conduits, fittings, and face plates that support or enclose wiring systems but do not themselves conduct current.
