two or more pins comprising at least a live pin and a neutral pin, at least the live and neutral pins including a through hole that extends through a central portion of a corresponding pin;
a ground;
a faceplate including an outer surface and a plurality of raised portions and lowered portions formed on an inner surface, some of the raised portions partially forming slots through which at least two of the two or more pins extend, and one or more of the raised portions forming a bracket positioned on an inward facing surface of the faceplate, material forming the faceplate filling the through hole of each pin;
at least one temperature sensor for monitoring a temperature at a location of the at least one temperature sensor;
a holder for holding the at least one temperature sensor and adjacent either the live pin, the neutral pin, or both the live pin and the neutral pin;
first seals formed around the two or more pins and positioned on the inward facing surface of the faceplate, the first seals being supported by ledges formed within the slots and configured to fill any openings between the two or more pins and the faceplate;
second seals formed around the two or more pins and configured to cover the first seals with a material to protect the first seals from pressure and heat associated with an injection molded third seal in a form on an inner-mold that covers at least the second seals and the lowered portions of the faceplate;
a data cable connected to the at least one temperature sensor and configured to transmit temperature data to a controller that is not part of and is physically separated from the plug; and
