Abstract: Power receptacles with cover with an electrical outlet and a base attached to the cover. The base includes a plurality of spaced apart electrical contacts under the electrical outlet. At least one of the cover or the base includes at least one internal attachment member that cooperates with a receiving channel in the other of the cover or the base to frictionally attach the cover and base together. The at least one attachment member can be a plurality of such members and one or more can include ribs, optionally crush ribs.

Abstract: Terminal assemblies for power receptacles or switches or other electrical devices include a first terminal holding a first terminal screw and a second terminal adjacent the first terminal and holding a second terminal screw. The terminal assembly also includes a thermal protection plate having longitudinally opposed first and second end portions, the first end portion affixed to the first terminal and the second end portion attached to the second terminal. The thermal protection plate has an electrical conductive contact residing between the first and second end portions, closer to the second end portion than the first end portion. The thermal protection plate has a first material with a first thermal coefficient of expansion overlying or underlying a second material with a second thermal coefficient of expansion with the second thermal coefficient of expansion greater than the first thermal coefficient of expansion.

Abstract: A combination AC receptacle and low voltage class 2 power units are provided in a standard single strap flush wall-mount outlet so that portable battery operated electronic devices may be charged without having to use a special AC charger. Ground fault circuit interrupter (GFCI) and/or arc fault circuit interrupter (AFCI) capabilities are also provided so that this combination AC receptacle and low voltage class 2 power units, e.g., USB receptacles, may used in occupancy locations requiring such protections under current electrical building codes. A standard wall cover plate is used to finish off installation of this flush wall-mount outlet into a wall outlet box. Also a data interface may be provided to allow a PDA or PC to control smart wiring systems through the USB receptacle.
