Hi All

A customer I was working for last week wants me to go back & move a light
fitting in their bungalow. Only needs to be moved by about 4 ft.

Haven't looked at the ceiling rose yet (very high ceiling), but whilst in
the loft I had a look at the 'back' of it and saw 4 x 1.5mm cables going to
it. None of them are long enough to reach the new location.

One must be the power in, one the power out and one the switch - but what
about number 4? 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 4 and 6 terminal JB's, and use whichever is best.
I always use 20A JB for lighting, as it's so much easier to
get multiple conductors into the larger terminals.
