Abstract: The present invention relates to electrical wiring devices such as electrical receptacles, switches, and the like, and more particularly to wiring devices with a clamp for the ground connections to such devices. The present invention includes a pressure plate which engages the ground plate of a receptacle with legs of a pressure plate disposed within correspondingly shaped recesses adjacent the ground plate of the receptacle, so that the pressure plate is substantially constrained from rotation relative to the ground plate so that a wire can be received between the ground plate and the pressure plate when the screw is backed out a sufficient distance.

Abstract: A package for an electrical floor box of the type adapted to be mounted in a sub-floor for receiving a wiring device to allow connection to an electrical circuit includes a cardboard container having a size sufficient to permit the floor box to be contained therein, a reclosable flap for allowing the cardboard container to be opened for receiving the floor box and closed to enclose the floor box in the cardboard container, and indicia on the surface of the cardboard container defining the perimeter of a portion of the box adapted, when separated from the remainder of the container and folded, to form a temporary cover for the floor box for at least partially closing the container.

Abstract: A reinforced thermoplastic elastomer wall plate having a mounting hole and a mounting screw retained in the opening by a web, and a packaging system for the wall plate which includes a flexible wrap and a reinforcing fin seal overlaying the screw are described.

Abstract: A wiring device such as a switch or receptacle includes a sheet suitable for receiving markings from a pencil or ball-point pen affixed to a predetermined surface area of the device. A conventional wall plate is secured to the device by a screw passing through coaxial openings in the wall plate, the sheet and the surface area of the device and secured in a threaded opening. In the disclosed embodiment, the device is a duplex receptacle with the surface area and sheet lying between the two plug-receiving portions. Indicia placed on the sheet by the installer indicates the specific circuit, i.e., the breaker and panel, in which the device is connected.

Abstract: An electrical wiring device, disclosed in the form of a duplex receptacle having the usual cover, body, terminals and mounting strap of the type extending longitudinally of the body rear surface and along the end surfaces. Two pairs of ribs are formed integrally with the body and extend in parallel relation longitudinally of the body rear surface with the strap lying between the two pairs of ribs. The purpose and effect of the ribs is to form a physical barrier of dielectric material and to lengthen the surface distance between the strap and portions of the hot and neutral wires terminated on the sides of the receptacle from which the insulation has been removed, thereby inhibiting electrical contact or arcing between the bare wires and the strap.
