from your MCB box with neighbors MCB box, then its cheating.

If internal looping wouldn’t be done, the number of wires and color coding would increase, thus causing lot of confusing for connecting the wires.

And thicker the wire, more durable it is.

Where ever loping needs to be done, thicker wire is used.

Labor work for doing wiring for every single point is reduced, therefore saving on your material and labor expense.

This loping of wire done inside the house is called as internal looping.įew advantages of having internal looping are. And this is how and why you have 1 single circuit for 10 lights and in-turn 1 switch that controls these lights. Suppose you have 10 lights in your living room, the neutral wire gets looped between these 10 lights internally and you have 1 neutral wire finally get connected to the main switch point to complete the circuit. Let me give you an example to help you understand it better. Also I t becomes necessary to loop neutral wire is it is difficult to pull neutral wire for longer distances and have separate neutral wire for each and every light/fan connection. That is it carries electricity from the output device back to the service panel/board.Īs neutral wire carries charge while returning, it doesn’t get heated up much. Neutral wire is a return wire for the current in an electrical circuit. Usually looping is done for neutral wire. Electrical looping is loop/loops created between two light with 1 single wire connected to multiple fittings.
