wiring a new light fitting

ROSENMARSH

Hi

My bathroom light stopped working, I have replaced the bulb with no improvement. The old unit is no longer in supply so I will have to buy a new light fitting. I have put in light fittings before but am somewhat confused by the wiring coming out the ceiling
The light pull also operates the fan simultaneously but I assume this has nothing to do with cabling in the ceiling as fan is in different location.
So there are three cables:
Cable 1 has a 1 black, 1 yellow-green and 1 red wire coming out.
Cable 2 has 1 black, 1 yellow-green, 1 red and 1 blue wire coming out
Cable 3 has 2 reds and 1 black coming out.
There is a single yellow wire coming out of the ceiling hole but which is not coming out of any cable.

All four reds are bonded together in a seperate connector.
The 2 yellow-green wires are bonded together with electrical tape.
Black from Cable 1 is bonded with yellow one half of a connector
Black from Cable 2 and Black from Cable 3 are with blue in other half of same connector. This connector was wired to the old light fitting although I forgot to note which way round the neutral and live wire from the old light fitting went in.

I have not bought the new light fitting yet but assume it will have seperate earth, neutral and live socket. I assume that I put the green-yellow in the new light fitting earth connector earth socket but am unclear about the neutral and live configuration?

Apparently Ias a new user (I have posted once before) I am not allowed to post photo links but I have three photos on my computer if there is any way round this..


Hope you can help

i think you will find that as the work is in a bathroom it comes under part P even though you are just replacing like for like, & not being rude but you haven't got the first clue as to what you are doing, yes the fan will be linked to the light if they both come on via the pull cord.

Also the earth is only required for a Class 1 (metal, or exposed metal parts) fitting, a Class 2 fitting requires no earth as it's double insulated.

You don't have a neutral, you have a live and a switched live, unless you took a photo before removing the cables form the old fitting or the switched live is marked (normally tape around the actual core insulation of the wire) then you need to now determine which is which.

The yellow is for the fan by the sounds of it.

You need to determine which is live and which is switch live, a proper way is with a multimeter/continuity meter (and a wander lead), do you own a multimeter?

I'm not going to advise the cowboy way, even though some sparky's resort to it.

you did actually read the OP's post didn't you ? does it sound like they own & know how to use a multimeter ?

What, the Irish mains tester ploy, akin to the Irish mine detector.

All done at arms length.

Sorry guys, it's a joke.

The above advice is correct, but maybe the bit the op, and a load of others don't get is that a timed fan requires a constant live feed, not just the switched feed from the switch itself.
