ABSTRACT:
Different line-cord sets connect an electrical device to different supply voltages, assuring that the supply voltage matches the device. Each line-cord set has a uniquely keyed socket and a wall plug. A device receptacle receives the line-cord's keyed socket. An adjustable key on the device mates with the socket's key and rejects nonmating sockets to admit the socket into the receptacle and adjusts the device's input voltage to match the supply voltage.
