Abstract
The present invention provides a wireway assembly for mounting to the housing wall of an electrical distribution device to enclose and protect electrical wiring therein. Generally rectangular, u-shaped channels have at least one aperture positioned in the channel wall to overlap the aperture of an adjacent channel to define a wireway through which the electrical wiring extends from the bight portion of one channel to the bight portion of the adjacent channel. An interlocking means manually attaches and detaches each channel with an adjacent channel and with the housing wall. The present invention also includes a method of safely protecting electrical wiring extending across a housing wall of an electrical distribution device. The method includes the step of interlocking a plurality of u-shaped channels in an abutting position to each other and the housing wall.
