The live wire
Carry electric current when the connected equipment develops an insulation fault
Returns current to the source
Carries the source alternating current from the power grid to the household loads
The function of industrial and multiphase plugs and sockets is
To reject any plug, which is not built to the same electrical standard.
To provide a connection to the electrical mains rated at higher voltages and currents than household plugs and sockets
To reduces the power load on the cables
