    Depends on the wiring method tbh.

    What've you got at the light? I'm guessing:

    The blue/brown is a normally a live and neutral to the light fitting. A brown/brown, it's most likely a switch-wire and a live-wire going to, and coming from the switch. Brown/brown is also used as strappers but you wouldn't find them at the light.

    Again, what have you where?

    As far as I know, yes. The live and the switch-wire must both be brown in a domestic dwelling.

    agreed, it should be brown, but some places the installer bring 220V to the switches and link out all the blues, link out all the earths and bring an earth, blue and a brown to the light, it's not the way to go but who knows what you have in there to begin with.


    So its brown for the switch wire regardless, but sometimes the neutral is needed from the switch to the fitting
