I have been asked by a mate to complete the wiring for his basement refurbishment. He had an old sparky mate wire out most of it and the ceilings are now up. The spark has had a heart attack and I have been asked to finish. I am competent although he has wired a way I haven't seen before He has fed the PL to the switch instead of the ceiling rose and a T&E to the rose. He has installed a 3 core and earth between switch 1 & 2. Although I know how to connect it together for a 1 way to the rose no problem, but am struggling to get my head around 2 way switching for it. Do I move the PL to L1 move and SL to L2 on switch 1, then link the com to com, L1 to L1,L2 to L2 using the link cable between the switches Then link the N using a strip connector.

Hi,

welcome to UHM.

This is a nice easy one-

It doesn't matter if the PL is at the switch or ceiling rose :wink:

Hopefully it will become clear when you see the page above, any problems please post back.

Missed the bit about the Neutral, yes these are normally connected together in the back box using a strip/terminal connector.

I looked at that info but got slightly confused as when I have wired a light up before my PL is in Com and SL in L1. The photo looks like PL to L1 and then SL to COM. What are my brain cells missing today.

Don't think it matters which way around the PL and SL are, as long as one is in L1 and the other in L2

Many thanks UHM. Just clicked in my brain. Wired the normal way you are still providing a PL to the switch just via the ceiling rose.. DOH

Yep :wink:

It can be confusing though, I made quite a few diagrams on lighting and sometimes I have to look at them a few times lol
