A combination electrical box, plaster ring, one or more electrical devices installed in the plaster ring and one or more pre-wired grounds between the electrical box and the electrical device or devices provides for a pre-tested ground path.

Further, it is impractical to test each wired installation for conformance to construction standards.Ī pre-wired power distribution system, in contrast, advantageously combines installation flexibility, convenience and verifiability. SUMMARY OF THE INVENTIONĬonventional electrical distribution systems consist of either prefabricated components customized for particular electrical distribution points within a building or individual components that must be planned for, ordered, allocated to building locations and then attached together and wired during installation at each electrical distribution point. During a trim phase, electrical devices are mounted to the plaster rings. Then power cables are fed through openings in the rear or sides of the boxes and folded back inside. A journeyman electrician routes power cables through building framing to the appropriate box. During a roughing phase of construction, electrical boxes with attached plaster rings are mounted to wall studs at predetermined locations. BACKGROUND OF THE INVENTIONĪ power distribution system may comprise an electrical box, a plaster ring and an electrical device, such as an outlet or switch.
