Abstract
The present invention is directed to an electrical wiring device that includes a plurality of line terminals, a plurality of load terminals, and a set of receptacle load terminals. The device includes a fixed contact and a first cantilever member including a first contact disposed thereon. A second cantilever member is disposed between the fixed contact and the first cantilever. The second cantilever member includes a dual contact disposed thereon. The dual contact is disposed between the fixed contact and the first contact. An actuator is configured to move between a closed position and a tripped position. The actuator is configured to urge the first cantilever toward the second cantilever to close the fixed contact, the first contact, and the dual contact such that the plurality of line terminals, the plurality of load terminals, and the set of receptacle load terminals are electrically continuous in the closed position. The actuator is also configured to release the first cantilever from the second cantilever to open the fixed contact, the first contact, and the dual contact. The plurality of line terminals, the plurality of load terminals, and the set of receptacle load termina…
