For a lamp we want two wires; you are the neutral wire as well as the other is the live wire. These two wires are connected through the lamp for the main supply panel. It is advisable to use different colours for live wires and neutral wires. The universal practice is to use along with red for live wires as well as a black colour for the neutral wire. For switching ON and OFF the lamp we need a control known as a switch - provided inside live wire between the main supply and lamp. If the switch is ON, the electric circuit is closed and also the lamp glows, and if the switch is OFF, it'll disconnect the ability supply on the lamp. For safe operation this wiring is positioned in a box known as a switch box. The switch wire and live wire certainly are a single wire; it's just cut among for connecting the switch. In case you want to change the lamp, don't forget to switch OFF the lamp and if possible disconnect the electricity supply towards the circuit.
