Bathroom light/fan/fuse box wiring...

[Joel Armsden]

Hello all,

I've recently moved into a new house to find the extractor in our bathroom not working. In addition, the 3-bulb halogen light fixture has now given up so I was planning on replacing with a couple of LED spots and fixing the extractor at the same time.

Taking the halogen fixture out, it seems the wiring is a little more intricate than I was hoping! Now contemplating just replacing the fixture like for like but thought I'd post here first for your advice, tips and comments on the current wiring, as per my image below...

Next, I took to the fuse box in the cupboard next to the bathroom, to find the wiring not even connected!

Any advice?!

Thanks in advance!!

Not labelled - Line(live) input, Line to switch and Permanent Line to Fan. The unconnected wire is presumably why it isn't working.

(N) - correct Neutral.
(E) - correct Earth.
(L) - Black Switched line and Yellow Switched line to fan

Just seen disconnected switch.

Are you sure that is the same cable?

Thanks so much for your replies! So the wiring at the fixture looks correct?

You're probably already aware but the 2nd image is the fuse in the adjacent cupboard, not the actual light switch.

I'm almost certain it's the 2nd grey cable that enters the ceiling - it runs in that direction of the cupboard from the the light fixture.

You need to be more than almost certain!

Invest in a sub-£10 multimeter from Maplin or the like and, with all the power off (check with the multimeter it is off), use the continuity setting to test one end of the suspect cable.

If you short R&B at one end and the other to the MM, if it is the same cable, it will bleat.
