First Day of AM2 exam finished! Just need alittle bit of help.

Erm I might be reading it wrong but you’ve took a live and neutral feed to 1st switch but then taken a 3 core and earth to 2nd switch and for an intermediate switch for 2 and 3 way control.
If so then why have you made the grey from the 3 core a neutral?
If it’s 2 way then black as common marked with brown over sleeving and the grey wants oversleeving brown also as it’s a strapper.
The only neutral you should have in the switch is the mains fed one from the DB then out to your light.

If I’ve miss read your txt then ignore me.

Oh well I wired it as this drawing is drawn. You have to loop a neutral in the back of the switches. So I took a L and N to the first switch to feed the common and Neutral in the back of the switch.

Then a 3 core taking two S/L to the intermediate from the first switch. Looped Neutral in the back again. Then a length of 3 core to the other 2 way switch which has a 2 S/L’s and a neutral. Again looped in the back. Picked uo the neutral in the back and up to the light on a seperate 1.5 which then brown to the common up to the light ?

Is this wrong? Or right?

I just followed this drawing.

Heres the drawing

On the AM2 they require a neutral at each switching point on the lighting circuit.

So T&E from MCB to 1st switch. 3C&E to intermediate and 3rd switch, then T&E to luminaire.

Technically you can use an colour core for strappers, neutral etc as long as their identified/sleeved.

So what ive done is correct then in my exam? Im panicing like hell now!?!?

Do it as per drawing Ryan it’s what you have to do and it shows you can read drawings also.

So there’s a neutral at the intermediate switch? Which is pointless.
Am I reading that right?
Different from when I did it.
It was about 17 years ago mind

There will be a N at all 3 switches in a wago I should imagine or some other connector.

Yeah thats what I done...

So what I done is correct and not wrong?

It’s to allow for smart switching. But TBH I would think it’s to check you actually follow the wiring diagram rather than just wade straight in.

Personally I think they should do one circuit this way and one using the three plate method.

We got told to loop the neutral in the back because some of the new switches have looped Neutral Terminals in the back of them now. Its also at a later date some new smart heating technology stuff needs a neutral at the switch. Hense why its been advised to do it this way.

That’ll work. Have fun wiring up the heating...
