240 Electrical Plug Wiring Diagram. It reveals the parts of the circuit as streamlined shapes as well as the power and also signal links between the devices. The four wires consist of two hot wires which are normally black but are sometimes red.
In 12 2 10 2 and 8 2 cables both wires are hot and carrying 240 volts between them with the white neutral line absent.
