Abstract

A power cord with leakage current detection function includes three copper wires for carrying power and at least one leakage current detection conductor for detecting leakage current. Each copper wire is surrounded by an insulating layer. At least two of the insulating layers are each surrounded by a metal conductive layer. The leakage current detection conductor is adjacent and in electrical contact with the two metal conductive layers. An outer insulating layer encloses the three wires and the leakage current detection conductor. The metal conductive layers are made of a thin copper foil, tin foil, aluminum foil, or conductive rubber. The leakage current detection conductor may be formed of copper wires or aluminum wires. Such a power cord provides low cost and reliability, and can quickly and accurately detect leakage current in the cord.
