Wireway is designed to protect electrical wiring from dust, dirt, oil, and water. It is also designed to carry electrical feeders, branch circuits, and other groups of conductors. Most sections and fittings are completely open on one side so wires and cables can be laid in along an entire wireway run. No pulling through of wires or cables is required with most designs. Wireway can be used for a variety of applications and, in most cases, can be installed faster and at less expense than conduit. This wireway is a NEMA 1 straight length with knockouts and a hinged cover. This unit is 4in by 4in and 5 feet long. All wireway is UL listed under file E27524, 870, and CSA file 42184, Type 1.
