ceiling rose confusion

[333rocky333]

I would have made an assumption that the two 3c&e cables at the ceiling rose went to the two switches with both blue and yellow connected together. One red being switch live, the other being switch return.

The wiring in the 2 switches that operate th lights are: L1 Yellow, L2 Blue with Red sheath and Red common. The other switch is exactly the same.

Another option at the old rose, was the two blues were in the Loop, two yellows in the switch line and the two reds joined through.

As for the 3 core in the second rose

Yep - 2 options but neither seem to suit what we have here.

All, I'm over whelmed with the help you're all giving me on this - it's restored my faith in human nature ! I'm moving house tomorrow (which was why I was removing the expensive light and replacing with a pendant)... I can't spend today working out whether what I've done is ok... but everything works as it should with no other lights un-duly affected and nothing buzzing or getting warm! It's working fine. From what you've all said, I don't have a standard wiring set-up... but it's working ok. Is there any danger in leaving it as it is lads?

according to your diagram you have two 2 core cables and two 3 core cables.

if you are certain it all works ok, can you confirm that;

1) a 3 core cable goes to the second light
2) a 3 core cable goes to a switch

this may have been wired in 3 core to provide;
1) a permanant live indirectly to the second light which may feed something else somewhere (like lights in another room)
2) a neutral at a switch (possibly a multiple gang switch feeding an outside light for example)
