Abstract
Abstract A box member is provided for containing electrical distribution circuits, including circuit breakers, and which has a front wall, a back wall, side walls and end walls, with an electrical inlet receptacle located on one end wall of the box. A receptacle support member extends rearwardly from the box back wall and has a rear surface, side surfaces and end surfaces. The side-to-side width of the support member is substantially smaller than the side-to-side width of the box member, and the support member is preferably centered with respect to the side walls of the box member so as to form a "T" shape configuration. At least one electrical outlet receptacle is also located on each side surface of the support member, and each outlet receptacle extends outwardly and downwardly from its support side surface but does not protrude beyond a side wall of the box member. The distance between the front wall of the box member and the rear surface of the support member is approximately equal to the side-to-side width of the box member.
