Abstract: A feed through receptacle box assembly includes a base and a housing for supporting a receptacle and connecting to a raceway. A channel member is removably coupled to the base to provide a closed passage for feeding a wire or cable through the housing to isolate the wire or cable from the receptacle. The receptacle can be a duplex electrical receptacle or a telecommunications port that is connected to a respective wire or cable passing through the raceway. In embodiments, the channel member includes at least one intermediate wall forming a plurality of side-by-side passages. The channel member includes frangible lines for separating a portion of the channel member to allow access to a respective wire or cable passing through the passages of the channel member.
