Abstract: An electric receptacle for trade size outlet boxes having a ground fault circuit interrupting mechanism incorporated therein. A receptacle housing includes contact jaws seated therein to receive the plug of a conductor leading to a load, electronic components to detect a ground fault and grounded neutral condition on the load side of the receptacle, plus a coil and trip mechanism to open the receptacle circuit on occurrence of a ground fault or grounded neutral condition. The complete receptacle assembly is approximately the same depth as conventional household receptacles which do not have ground fault circuit interrupting means included therein. Means to periodically test the ground fault interrupting mechanism is also included in the receptacle assembly, as well as means to indicate the circuit has been interrupted and means to reset.

Abstract: A captive fastener assembly, comprising a guide rail structure, a screw mounted thereon for linear movement relative to the guide rail structure but restrained from rotational movement, and a captive nut mounted in a cooperative bracket for rotational movement but restrained from linear movement relative to the bracket. The invention is particularly useful in fastening various work pieces together, such as an electric terminal box and a meter cabinet, the guide rail structure being mounted on one of the work pieces with the screw captively in place and the bracket secured to the other work piece with the nut captively mounted therein.

Abstract: An auxiliary gutter to receive, secure and house cable for connecting to an adjacent load center. The end walls of the gutter have a recessed edge region or notch intermediately thereof with cooperating clamp means to lay-in and secure lengths of cable without cutting. Wiring cable may thus extend unbroken in one continuous run from the top floor of a building to the bottom and connect to load centers on each floor by laying in cable and clamping to respective auxiliary gutters mounted along side each load center. Tap kits connect the cable electrically to the load centers. A cover is provided which has universal features, including a break-away tab and uniquely positioned mounting holes, making the cover useable with installations where the load center is the same length as the auxiliary gutter, where the load center is shorter than the auxiliary gutter, where both are flush mounted, and where both are surface mounted.
