Loop in at The Switch - 3 Gang 2 Way

[bjd91]

Hey,

I've just past my trade test and was placed on a new build to complete the 2nd fix
as the guy who roughed it has left.

Anyway, he's wired the lights using the loop method at the switches, I've never did this
previously as I would always do the joint at the ceiling rose, this has thrown me
when it came to connecting a 3 gang 2way switch at the top of the landing.

There are 2 feeds, 2 switch wires, a 3 core (2way) and a fan cable.

What's the correct/best way to connect this?

Any help appreciated

Thanks

Carry out a continuity test on each cable to prove where they go. Then connect them up accordingly.

bell them out. draw it out on paper, then wire up. unfortunately there ain't a app for this.

Rip it all out and 3plate it, at the celling. lol Eng would agree.

It is very easy, have a think about it, tell us your thoughts and then we will tell you either way

Theres going to be alot of conductors there but you just have to (firstly stay calm ) slowly work out which are the P/L, S/L and N. Just keep doing continuity tests until you have found them all.

Like Tel says, I really find it useful to draw it out and once you've drawn it out you'll think 'thats fairly straight forward', but dont throw the diagram away just yet, wait till its all wired up!!

Have not got a clue D ?

No Idea, but I bet you can obtain it with 4k and 5 weeks at a training centre.

I think it's the term used for the Scottish equivalent of the AM2, i.e. last practical exam in completing your qualification route.

It seems to be a Scottish version of the AM2

You need to picture in your mind the working of the circuit , not just do things in a way that because its not as you would normally do things that makes it impossible to understand , visualise what your working with ..

And a lot of neutrals in that back box, hope it's deep enough.

 

[Resu]

Start by getting your neutrals and CPCs out the way (being careful of your 3cores,) that should help!

And a lot of neutrals in that back box, hope it's deep enough.

5Neutrals, 6'CPCs, 6 permanent feeds, 2 or 3 switch wires and 2 strappers. A 25mm box should suffice unless dimmers or flush switches are used.

It's where they give you a 3 gang 2 way looped at the switch and tell you to get on with it.

 

[Silly Sausage]

Neutrals at switches is the way to go.
Dismiss what the dinosaurs say.

I like that Geordie ha ha. funny lol.. lol

You sound like some sort of guru Ray! I can just imagine you seated in front of the almighty swith, picturing and visualising it's inner workings.

If you can 3 plate a ceiling rose then you can do this too. Think about it for a minute its obvious really.
