Application and General Information
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.
The Square D™ Wireway products, manufactured by Schneider Electric, are available in the following types:
-
General Purpose—NEMA Type 1 Painted Wireway
-
Oiltight—NEMA Type 12 Wireway
-
Raintight—NEMA Type 3R Wireway
-
Raintight—NEMA Type 3R Trough
Oiltight—NEMA Type 12 Wireway Tee, Flange Gasket, Connector, Barriers with Brackets, 90° Elbow (clockwise from top)
All wireway is UL listed under file E27524, 870, and CSA file 42184, Type 1.
Wireway can be used for a variety of applications and, in most cases, can be installed faster and at less expense than conduit. Applications include:
-
Incoming cable runs and feeder circuits from switchboards to power and lighting panels
-
Distribution of power in industrial plants
-
Ganging equipment such as motor controllers, safety switches, and metering devices
-
Vertical runs of cable in elevator shafts
When comparing wireway with conduit, wireway provides the following advantages:
-
Weighs less and is reusable
-
Is easier to install
-
Allows conductors to be laid in
-
Makes additions to the wiring system easier
-
Provides provisions for tap-offs
