A power cor or mains cable is a cord or cable that temporarily connects an electrical appliance to an electrical power source. The term is generally used for cables using a power plug to connect to a single-phase alternating current power source at "mains voltage" (100 to 240 volts, depending on the location). The terms power cable, mains lead or flex are also used. The term cord set is also used to distinguish those cords that include connectors molded to the cord at each end.
