I have a loop-in lighting system and have recently had an extension
with lots of new rooms to decorate and add decent lights to. The
builders just installed basic ceiling roses with the plastic 8 slot
connectors plus metal earth connector.

I've ascertained how to wire up the new light fittings using connectors
so that I'm left with just the single Live and Neutral wires (plus the
earths). However, because there are up to 5 cables involved, there are
too many wires to fit into single connectors. I think I'm right in
saying that I could daisy-chain these connectors until I'm left with 1
wire for each - but I decided instead to remove the plastic connector
strip from the rose and re-use it as well as the separate metal
connector block from the rose for the earths.

I would have liked to have pushed this connector strip up above the
ceiling plasterboard, as well as the earth connector, but the hole in
the ceiling is not big enough. Rather than make a bigger hole, I left
these connectors below the ceiling and fitted them inside the recess of
the light fitting. I did insulate all connections with electrical tape.

Is what I have done acceptable, dangerous or somewhere in between? In
this particular case, the light fitting didn't have a transformer in
it, but I do have other lights to put up which do have one - should I
be more careful in this case about leaving the connectors inside the
light fitting?

I'm a newcomer to fitting lights with a loop-in system - so please be
gentle - although I did talk through what I was doing with someone with
electrical knowledge.
