Wires
There are usually
three wires
in our home circuit:
Live Wire
Neutral Wire
Earth Wire

Potential
of wire
Function
Live (L)
wire
Brown
240 V (high)
Allows electric current to flow from source to appliance.
Neutral (N) wire
Blue
0 V
Allows the same current to return to the source and complete the circuit.
Earth (E) wire
Green/Yellow
0 V
