1. An electrical wiring device including a plurality of line terminals, a plurality of load terminals, and at least one set of receptacle load terminals, the wiring device comprising:

  • at least one fixed contact;

    at least one first cantilever member including a first contact disposed thereon;

    at least one second cantilever member disposed between the at least one fixed contact and the at least one first cantilever, the at least one second cantilever member including a dual contact disposed thereon, the dual contact being disposed between the at least one fixed contact and the at least one first contact; and

    an actuator configured to move between a closed position and a tripped position, the actuator being configured to urge the at least one first cantilever toward the at least one 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 at least one set of receptacle load terminals are electrically continuous in the closed position, the actuator being configured to release the at least one first cantilever from the at least one 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 at least one set of receptacle load terminals are decoupled in the tripped position.
