ABSTRACT:
An electrical raceway assembly having a channel-shaped cover and a plurality of receptacles mounted in the cover. A pair of cover sidewalls have free edges bent toward one another, and longitudinally extending recesses are formed in opposite sides of the receptacles in confronting relation to the free edges on the cover sidewalls to provide a pair of by-pass conductor compartments with the free edges of the cover sidewalls serving as conductor retaining jaws. This invention also discloses an electrical receptacle assembly featuring a receptacle face cap removably fitted over a raised front face of the receptacle. The face cap has projecting flanges which may be interposed between the receptacle and its cover plate to secure the face cap in overlying position on the receptacle face.
