Abstract: An electrical plug having an additional fuse connecting between the metal prongs in an outlet connected to a power source and the power cord connected to electrical equipment with the fuse having fuse strips along one face of an insulator block and up opposite faces of the insulator block on opposite ends of each of the fuse strips. The insulator block has a threaded hole therethrough aligned with a threaded hole in the bottom of a space or cavity in the plug with a screw threaded through both holes to maintain the insulator block in the space and in tight electrical contact with the tips of wires from the power cord and the edges of the prongs.
