I replaced a standard light pendant and although everything works I am
slightly confused about the light circuit. The celing rose consists of
three separate cables (one double core, the other two both single
core). One of the double core cables goes to the live junction in the
ceiling rose the other to the earth connection. Both single core
cables (twisted together) go to one of the neutral junction terminals
(nothing goes into the loop section of the ceiling rose).

The only idea I came up with is that the neutral loops round all the
ceiling roses and the same thing happens on the live side in the
switches (which in the room where I replaced the pendant also has
three separate wires going into the switch). So I have a ring lighting
circuit?

But again I am not sure so any suggestions are welcome

Thanks

Nick
