Changing light fixtures (wiring mess)

asweby · Jul 15, 2018

Afternoon all,

First time poster, hope this is the right place, looking for some advice.

I’ve removed a three bulb light from a bedroom ceiling and revealed a mess of wires protruding from the ceiling. I’ve got two white wires, each with a black, red and earth wire exiting, and two grey wires, one with two red and an earth exiting and one with a blue, brown and earth exiting.

There’s only one light switch in the room and I just want to install a bog standard one bulb ceiling rose, which I’ve installed a few times before.

I can make sense of the attaching the ceiling rose but I’m wondering about all the superfluous wires and what to do with them.

I’ve read about capping them off, tracing back the wires to the source etc, and I’m looking for the most straightforward process for a relative layman.

Any advice would be appreciated.

Reds of the white cables along with one red from the grey cable to the loop terminal of the rose. The blacks into the neutral and the other red of the grey cable to the live terminal. Brown of the new cable also goes to the loop terminal and blue to the neutral, I am making an assumption with this cable. Earths sleeved and to the earth terminal.

Can't see a "mixed wiring" label anywhere...

No offence, but just pay for an hours work by someone qualified. If you've previously installed ceiling roses you should be able to sort out the basic wiring but testing is required to be certain.

Thanks Westward, you make it sound so easy

Pirate, what do you mean by mixed wiring?

Ignore the mixed wiring bit, can you post up a pic of the rose terminals.

Pirate is poking fun at us ... There is a regulation that says your installation should have a warning sticker on the consumer unit due to the conductor insulation colours

Thank you Wilko, I was just being a bit facetious as the tennis is crap!
Frankly, I like the old white sheathed t&e, and the twin red stuff. Got a couple of drums in my garage if anyone wants it, FOC.

One of the reds from the grey cable to L. All other reds to the Loop including the brown wire. Blacks including the blue to N. The bare copper wires to the stand alone terminal with green/yellow sleeving fitted. The only downside is that ceiling roses are designed for three cables, you have an additional one which means one terminal at the Loop and one at the N will have two wires connected.

….therefore could be a bit tight, if you're not used to it.

I am guessing they are 1.0 as the conductors look the same size as the cpcs so might not be too bad.

I doubt if the spark that used the twin red and earth on the install would imagine that he’d make a DIY’rs answer so much easier for the forum members.
Always with @PEG s advice of getting an electrician in for an hour if it gets out of hand.

All in and secure.

Not all the earths fit in to the standalone terminal but they are all twisted together and taped with electrical tape. Is that going to be a problem?

This is the 4th ceiling rose I've installed, but ipf has put the fear in me given that this is in my unborn child’s nursery.
