Simple Circuit Diagram For A Lighting Point

To install a light point we need a to create a simple circuit. An electrical circuit as mentioned before is just a loop that current travels through continuously non stop. To break this loop we use a switch. The continuous flow of electricity will light up any lights that has been designed to work with the specified amount of current or electrical supply.

With reference to the diagram above, run 2 wires from the main switch panel. It would be advisable to use two different color coded wires to easily differentiate where the wire go. In this example we shall use the red wire for the live wire and the black wire for the neutral.

The red wire or the live wire goes to the switch terminal, and the black or neutral wire goes to the light holder’s terminals. From the switch, run another wire to the light holder’s other terminal. This is the switch wire. You can see the Live wire and the Switch wire is actually one single piece of wire, cut off into half by the switch. If the switch is ON, it connects the wire back, if it is OFF, the wire gets cut off again. Thus you can switch the lights ON and OFF.

At the mains, (Make sure all the Mains have been switched off), connect the red wire to any one of the sub circuit breakers. The black wires goes to the neutral link which in fact is a thick copper strip with all the neutral wires connected together. Just try to squeeze another one in.

Now all you have to do is to terminate the switch and the lamp holder. Put in the bulb and you should have a working circuit. Now of course this is the very conventional way of doing things . In recent years, LED seems to be getting very popular due to lower cost and less energy consumption if compared to the normal lights we use in our homes. However I come from the old school and I’m not much of a help when it comes to these modern things. If you would like to find out more, try reading this article about LED Home Lighting instead.
