Conduit Loop-in Method for Wiring 2 Way and Intermediate Switching of a Lighting Circuit in Singles

Student training aid for terminating a lighting circuit using the conduit loop-in method. Full demonstration on how to wire 2 two way switches and an intermediate switch controlling a batten lamp holder wired in 1.5mm2 PVC single insulated cables in a PVC conduit training rig. The wiring and connections from the consumer unit to the light and two 2 way switches and the intermediate are explained along with a circuit diagram.

Nicely explained I wish my collage instructor was as clear at explaining thing as you guys are. Keep up the good work.

Good explanation. Don't forget there is another way of doing it if your permanent line and switched line are at the same switch. You'll need to run three strappers to each of the remaining switches and use connector blocks for the common strapper, or in this case where using singles you would run one between the first and last switch, and two between each of the switches in between. The method in the video only works if you have your permanent line at the first switch and switched line at the last switch.

Wow couldn't believe how simple that was 👍thanks

[DanstheEngineer]

Perfect Gaz. I was drawing this out to one of my apprentices this morning. I'll send him a link to the video!

[danfari]

wow!
very nice almighty God bless you and your family

[shajujohn]

Brilliant explanation really like it.
Very understanding 😊 thank you

[shajujohn]

Very helpful. Very easy to understand 👌👍

[alvinashman]

It would be great if you could do short video showing what the switches are actually doing when they are pressed. I can remember constructing a model (complete with moving parts) showing my apprentice what actually happens inside the switch when a 1-way, 2-way or intermediate switch is pressed. He found the model of the intermediate switch in particular, extremely beneficial.

Hi Gary, looking at that intermediate switch I think I’d remember the correct way to place the strappers, looking at this particular make of intermediate switch they look like arrows arrows showing the way < > . Not sure if it’s the same for other brands.
Regards steve.

Can you do a video or a wiring diagram of bringing the feed to the switch instead of going to the rose as on the am2E we have to bring feed to the switch

[ashleyhouseman]

Fantastic video, keep them coming so helpful!

[danielteyehuago]

I do have similar problem with the intermediate switch connection

[benhancock]

Hi Gaz so in the am2s now you would wire the neutral the same as the CPC leaving a connection at each switch before only having one cable at the night?

[Clydepatos]

Very nice video very clear explenation

[simonmorse]

In the AM2 it asks for the neutral to be at every switch, can you confirm that this is true?

[anjumshahzad]

So line going to the common of first switch and common of 3 switch to light

[TheNazm]

Would be great if you could use wiring diagram for this with colour pen

[bowevoorhees]

Gaz can you do a video taking feed to switch and neutral at every point please, as am2 want

[mikenjoroge]

Why is it that you used a brown wire only

[fatoumattacharty]

Sir tbr writing is biden your explanation and i don't know how you can help
