A sealed electrical plug, comprising: two or more pins comprising a live pin including a first plurality of grooves formed around the live pin and a neutral pin including a second plurality of grooves formed around the neutral pin; a bridge through which the two or more pins extend; a first temperature sensor for monitoring a temperature of the live pin, wherein the first temperature sensor is positioned on the bridge adjacent to the live pin, and a second temperature sensor for monitoring a temperature of the neutral pin, wherein the second temperature sensor is positioned on the bridge adjacent to the neutral pin; a first housing for holding the first temperature sensor in a first position on an inward facing surface of the bridge and configured to receive the live pin, the first housing connected to the live pin via one or more grooves of the live pin; a second housing, separate from the first housing, for holding the second temperature sensor in a second position on the inward facing surface of the bridge and configured to receive the neutral pin, the second housing connected to the neutral pin via one or more grooves of the neutral pin; a first groove seal of the live pin formed between the first plurality of grooves and the first housing, and a second groove seal of the neutral pin formed between the second plurality of grooves and the second housing, wherein the first groove seal of the live pin is formed by molding materials of the bridge to fill the first plurality of grooves, wherein the second groove seal is formed by molding materials of the bridge to fill the second plurality of grooves, wherein the first groove seal seals a passage between the live pin and the bridge to at least one of air and water, and the second groove seal seals a passage between the neutral pin and the bridge to at least one of air and water; a cable including a first conductor (154, 156, 158) and first insulation crimped together to form a first crimped seal at a first crimped portion where the first conductor is connected with the live pin, a second conductor (154, 156, 158) and second insulation crimped together to form a second crimped seal at a second crimped portion where the second conductor is connected with the neutral pin, a first data cable for conveying data from the first temperature sensor and a second data cable for conveying data from the second temperature sensor, wherein adhesive is applied between the first conductor and the first insulation at the first crimped portion and between the second conductor and the second insulation at the second crimped portion; an inner-mold covering the first and second temperature sensors, the inward facing surface of the bridge and the first and second adhesive seals, and the first and second housing; and an outer-mold covering the inner-mold. two or more pins comprising a live pin including a first plurality of grooves formed around the live pin and a neutral pin including a second plurality of grooves formed around the neutral pin;
