Fitting a light...

[heather2008]

Hi everyone,

I've got a problem fitting a ceiling light and the wiring is really confusing me, can anyone help me?

Most lights I've fitted have one or two brown and blue wires coming from the ceiling (along with the earths) and I put both together into the light fitting. This light has four grey cables:

3 have: 1x earth 1x blue 1x brown
1 has: 1x earth 1x grey 1x black

What am I supposed to wire the grey and black to?

I've tried every combination but it doesn't seem to work! With the blue and brown wired in normally the light goes on and stays on when I try to switch it off! Should I wire the random grey cable into it somehow? I'm wiring the four wires into a connection box then having a single wire coming from that to the light as it's easier to work with.

Many thanks,

Heather

Think you have this wrong mate , the poster has said there is one cable with 3 cores and earth , not mentioned a core being cut out.. the 3 core will be running the toilet extractor , the 3 twin an earths in new colours will be loop in loop out and switch wire.

not trying to catch you out as you obviously know your stuff , this is just the way i see it.....




cheers

not a problem ste,but how do you account for the black wire at the switch?There was by the way a mention that the grey wire may have been taped up at the ceiling. I recon the extractor fan is a red herring.And anyway to drift off here a bit why don't they give us a blue in
a 3core+earth,some sparks tape up the grey core with blue to sygnify neutral while others tape up the black with blue tape.This can lead to problems following behind another spark who has done one bit of the job,and someone else comes along perhaps a week or two later after the builder has got round to cutting out the hole in the wall for the fan.

come on everyone you should all say call an electrician no one even said anything about safely isolating the circuit how can you all advise incompetant people on how to do our job we are supposed to be against cowboys and diy ^ers , just hope this person didnt end up getting a shock or done a bad connection causing the wires to burn out or worse.

Quite right...call an electrician.....But then I supose we could say that about 90% of the posts on this forum......call an electrician.And don't forget to get us to come out and certify your mess,no chance! These people can also read books and I don't think if we just advise them to get an electrician every time,that it will stop them tinkering and blowing themselves up....
red to black and blue to fuk!
