Could be power out to another light - remember that loop in wiring does
not require a sequential daisy chain - you can take a feed to aother
lighting point at any place that is convienient.

As far as I can see it's the second from last light in the
building. It's all fairly new wiring as it's in an extension built a few
years ago.

I'll need to mark & note the way the cables are connected and fit a junction
box, but what type? 4 or 6 terminal? And would I be better off with a 20
or 30 amp to give more room for all those cables?

I would get one of the MK 4 terminal boxes. They have 4 individual
screew terminals on each of the four terminal blocks.


Another couple of thoughts which might work depending on the customer
and the location.

1. Leave the existing rose where it is and use it as the juntion box.

2. As above, but have a light from the existing and the new (might suit
them, might not).

3. Use the existing rose as in 1, but move it above the ceiling and
make good where it was. Not sure if this is kosher, you's prolly have
to close off the hole the wire used to come through at least.
