Patent ID: 7186137

Claim:
A cable for conducting electric current from a source receptacle to a load receptacle, the cable comprising: a primary cord including an electrical conductor with a first terminal end and a second terminal end; a ground cord including an electrical conductor with a first terminal end and a second terminal end, wherein the electrical conductor of the ground cord is separated from the electrical conductor of the primary cord by a dielectric material; a first plug adapted to conduct the electric current between a contact provided to the source receptacle and the first terminal end of the primary cord's electrical conductor; a second plug formed at least in part from an electrically-conductive material that contacts an electrically-conductive portion of a housing of the load receptacle when installed therein to establish an electric connection between the ground cord and the load receptacle, the second plug also being adapted to facilitate the conduction of electric current between the second terminal end of the primary cord and a contact provided to the load receptacle, wherein at least one of the first plug and the second plug is compatible with a single-prong receptacle; a first fastener electrically connecting the first terminal end of the ground cord's electrical conductor to the first plug; and a second fastener electrically connecting the second terminal end of the ground cord's electrical conductor to the second plug for establishing electrical communication between the ground cord and the second plug.
