Ceiling rose and its switch have an extra wire...

[Andrew]

Hi,

The ceiling rose i'm replacing for an old brass light fitting has three t&e cables, all fine(although all taped up and not in a junction box). However, there is an additional single core neutral wire terminating with the other two neutrals.

And in the switch there is (in addition to a single t&e cable) a single core livewire terminating with the neutral.

As far as I can tell, there is only one switch for this light. This switch is a double switch and the other has three core as it can be controlled from up and downstairs. I assume this has nothing to do with anything.

What are these mysterious single cores and where might they go please?

Also, I assume when I replace the rose I can simply put this extra neutral in with the others?

Thanks!!!!!

Hi,

Update.

There is a batton light in the hallway (which doesn't work and doesn't have a switch). I've just taken this off and there are two single core cables feeding it......

I'll change the light bulb and see if it works, but does this wiring suggest it's simply feeding another light.?

The bulb was blow. It comes on!

I've sorted it out

Still, this isn't dangerous, etc, is it?

Well done on sorting it... My first thought was a second light from a single switch. So long as the second light does not require an earth then it isn't dangerous.

Cheers. Should have scoped it out a little more first i guess!

The second light is a batton lamp holder and the two wires goes straight into this, so to me it seems okay.

Cheers.
