Abstract: An electrical outlet box includes channels in a female member for receiving in spaced apart relationship three conductors of an uncut electrical cable. One or more sets of three receivers mounted in a male member for electrically engaging each conductor interconnects the conductors of the cable and defines an electrical socket of a socket assembly of the electrical outlet box. A cover is attachable to the male member for covering the space between the socket assembly and the surrounding wall board aperture. Fittings are included and formed as part of the electrical outlet box to permit back to back attachment of a pair of electrical outlet boxes and for side by side mounting in a ganged manner of two or more electrical outlet boxes. Routing of the cable in slots in the studs of a wall is described along with a retainer for retaining the cable in the slots.
