Hello.
Been fitting new light fittings to my house and have cone across the first fitting controlled by 2 switchs. Wasnt thinging and just indid the wires from the ceiling rose. Now im stumped as to how to put them back.
Ive got what i believe is a 2 phase wire and a 3 phase wire. Can anyone help me as to where they go as the internet ia confusing me with old colours new colours and crazy diagrams.

2 phase wire has
Brown
Blue
Earth

3phase
Grey with blue sleeve
Black with brown sleeve
Brown
Earth

This is the information that you need:

I can only guess, but here goes.
1) It is single phase.
2) Three core cable is line (brown) centre on rose, neutral (blue) three terminal outer, and earth to clamp.
4) Four core cable is switch feed either Black with brown sleeve or Brown likely latter to centre. Then switch return, either Black with brown sleeve or Brown likely former to two terminal outer. Grey with blue sleeve to centre terminal to neutral (blue) three terminal outer and again earth to clamp.

I will guess the switch needs a neutral which is why you have 3 core and earth cable. However this is just a guess without testing can't be sure.
