LCDI power cord
A power cord with leakage current detection function includes an insulated neutral wire and aluminum foil wrapping or surrounding the neutral wire insulator. The neutral wire aluminum foil has a conductive side and a non-conductive side, wherein the non-conductive side is adjacent to the outside of the neutral wire insulator and the conductive side is facing outwards. The power cord also includes an insulated line wire surrounded by aluminum foil where the conductive side is facing outwards and in contact with the conductive side of the aluminum foil surround the neutral wire. The power cord also includes a copper braid surrounding an insulated ground wire, wherein the copper braid is in simultaneous electrical contact with the conductive sides of the line and neutral aluminum foil wraps.
