Ceiling Rose

[ajgeastwood]

Hi All,

Hoping someone can help me here. Just took down exisiting light fitting in bedroom and prepared to fit light with dan. Like an idiot I didn't label the wires as I removed the old rose.
I now have three sets of three core wiring. Red - Black - Green
Single switch in the bedroom.

What is the best way of determing the correct way to wire this up or identify which are circuit cables and which is the switch?

BTW as far as I can tell the landing light is on the same loop.

Thanks,

Ant

With a multimeter on continuity or low ohms setting

Normally one of the blacks will be used as a switch live from the relevent switch. This should be identified with red sleeving or tape.

Do any of the black wires have this?

If not then follow Adam's advice.

No distinguishing markers on any of the blacks.

2 options here,

1/ get hold of a continuity tester

2/If there is a loftspace above the bedroom then go up and trace out the switch wire.

Hi,

I believe I have identified cables 1 and 2 as the circuit cables and cable 3 as the switch cabel. However I can't seem to get the wiring in the rose right, having tried different permutations the pendant stays on permantley or the fuse blows or the second light on the circuit stays off.
Sorry to be a complete numpty but has anyone got a wiring diagram I can follow?

Yet again the FAQ has just the diagram
It's strange how I keep finding all these diagrams in there

Hi - if your connections are at the actual ceiling rose, rather than at a junction box in the rafters, this link has an illustration that should help (scroll down till you find the right image):
