What is the LOOP terminal on a light switch?
The loop terminal is used purely for a termination of a non/switched cable. Ie not active. Some light fittings will have a loop terminal that you would put the active in. Some sparkys prefer to solder wires together in walls, as it offers a better connection (reliable) than a screwed connection.Jun 21, 2013
What does loop mean on a light fitting?
Loop in allows you to carry electricity from one lamp to another lamp. Inside the ceiling rose of a pendant light there are four terminals: loop in, neutral, switchline, earth. Power comes into the light via a cable from the consumer unit, containing line, neutral and earth wires.

What does loop mean on the back of a light switch?
By using the loop at the light method, electricians can loop out to other lights along the same circuit, or even to separate lights which are switched on through other circuit boards. This means that two lights might have the same power supply cable but each of them could have their own individual switch.

What happens when you loop a switch?
Switching loops also generate broadcast storms, since the broadcast packets are forwarded to every port on the switch; the switch will repeatedly rebroadcast the broadcast messages, thus flooding the network. When this happens on your network, everyone will lose the ability to communicate on the network.May 19, 2016
Are switch loops allowed?
At the fixture end, one of the 2 wires the switch is connected to would be connected to the source of power (black on the other cables) and the other is connected to the hot screw of the light fixture. A switch loop wired properly is legal.

Why would a black and white wire be tied together?
Why are black and white wires connected together in the switch outlet? If you see both sides connected together, it means it's a switch loop. The white wire that's connected to the black wire carries power to the switch. And the black wire that's in the same cable carries back that switched power to the outlet.Apr 11, 2021
What is a loop terminal for?
The 'loop' terminal is an insulated terminal that is not connected to anything and is longer in depth than the other terminals because it is designed to connect more than 2 wires together. The 'loop' terminal's purpose is to join wires together which avoids having to use 'splices' or 'pigtales'.Aug 15, 2012
What is a loop in a light circuit?
Lighting Circuits - Loop at the Switch. This is a loop in method which can be useful where the light fitting only has three terminals, or when using downlighters.
How are in and out cables connected?
The in and out cables are connected together . Earth and Neutral from the light are permanently connected to the supply. Only the live and switched live connect to the switch. Remember that the switch simply connects two terminals together - when connected, the light is on.
What is the difference between a 'in' and 'out' cable?
The 'in' cable supplies power from the previous light or consumer unit. The 'out' cable continues to the next light. The 'light' cable goes to the light fitting. There will only be three wires at the light - live, neutral and earth. Useful with a fancy (or cheap-n-nasty) fitting which only has 3 terminals inside.
The historical method
Before the code changed, it was common to run a single length of 12/2 or 14/2 cable as a switch loop. This means bringing the power down from the fixture to and through the switch and then back up to the fixture.
Wiring a Switch Loop: The Historical Method
In the “old school” way of wiring a switch loop, a single length of 2-wire cable serves as a switch loop. The white wire in the cable is taped black to show that it is being used as a hot wire.
The modern method
This method of wiring a switch loop reflects recent code changes. Specifically, the NEC requires that there be a neutral in every switch box because some electronic timer switches and other energy-saving controls need a neutral. So if you want to use a switch-loop approach, you must use three-conductor (3-wire) cable.
Wiring a Switch Loop: The Modern Method
The NEC requires that there be a neutral in every switch box because some electronic timer switches and other energy-saving controls need a neutral. Thus, if you want to use a switch-loop approach, you must use three-conductor (3-wire) cable, connect the neutral at the power source, and then cap off the neutral in the switch box.
What is a Light Switch?
The light switch is an electrical component used to control and operate the lights, bulbs, the equipment connected with it, and any electrical outlet connected with it. Switches are of different types and are used for different purposes. Usually, the switches only do ON or OFF the device that is connected with it.
How a Light Switch Works?
When the current is passed through the switch to the load, that is, bulbs, ceiling lights, etc. It makes the light turn ON. But when you push the button to OFF the light, it entirely breaks the circuit, and the passing of electricity is interrupted. What happens is there is always a space between the hot wire and the switch.

It is essential to wire a light switch correctly. Wiring it incorrectly often leads to a fire in the switchboard that causes significant accidents. It may also give the electric shock. So, it is best always to consult the electrician to wire your light and switch.
