I thought of another reason for not doing it - anyone who doesn't
know the system won't know how to isolate it, other than perhaps
through the 3-pole isolator which is supposed to be fitted these
days.

Another reason will become clear if you consider that the ring circuit might
be fed via an RCD and the lighting circuit not...


I already mentioned that one in a previous reply.

More fundamentally though it violates regulation 314-01-04 which says that
the wiring of final circuits must be kept electrically separate.

And although I din't quote the regulation, I said as much in the same
one :-)

I can't find the beginning of this thread, but whomever it was that said:

The fan should be a spur from the upstairs ring main, not the
lighting circuit

wants locking up.


No, he wants educating. Someone who learns a lesson like this is more
likely to put it into practice than someone who hasn't thought about it
and blindly follows rules... or something like that... sorry, not quite
thinking straight as have had 2 hours sleep in the last 36 due to
arrival of offspring #2.

Hwyl!
