1. An electrical power cord plug comprising:
a body having a plurality of wire openings, a plurality of blade openings and a plurality of actuator openings, wherein at least a portion of the interior of the body is hollow, wherein each of the plurality of wire openings provides access from an exterior of the body to the hollow portion of the interior of the body, wherein each of the plurality of blade openings provides access from the exterior of the body to the hollow portion of the interior of the body, and wherein each of the plurality of actuator openings provides access from the exterior of the body to the hollow portion of the interior of the body;
a cover having a hollow interior portion and a cable opening that provides access from an exterior of the cover to the hollow interior portion of the cover; and
a plurality of contact assemblies positioned in the hollow portion of the interior of the body such that one of the plurality of contact assemblies is accessible from one of the plurality of wire openings, one of the plurality of blade openings, and one of the plurality of actuator openings;
wherein each of the plurality of the contact assemblies includes:
a contact member having a contact blade extending from the contact member wherein the contact blade is aligned with the one of the plurality of blade openings in the body such that the contact blade can pass through the blade opening and extend from the body;
a wire terminal including a clamp brace electrically connected to the contact member and a clamping member electrically connected to the damp brace, the clamping member being movable between a closed position where a wire can be clamped between the clamping member and the clamp brace, and an open position where the wire can be inserted through the one of the plurality of wire openings in the body and between the clamping member and the damp brace; and
an actuator extending at least partially through the one of the plurality of actuator openings in the body, the actuator being interactive with the clamping member such that movement of the actuator in a first direction causes the actuator to apply a mechanical load to the clamping member causing the clamping member to move from the closed position to the open position, and movement of the actuator in a second direction removes the mechanical load from the clamping member so that to the clamping member moves from the open position to the closed position.
