I'm trying to add some sockets to a bedroom upstairs, and I'm in the
process
of working out how best to break into the ring and extend it by a socket
or
two. (We have 1 double socket in each of the two larger bedrooms and a
single socket in the small bedroom! What a waste of a 32A MCB)

What I'm after really is an idea of the size of wiring I need to use to
extend the ring (I'm planning on just breaking into it at an existing
socket, and then taking one wire to a new socket, and then joining the two
sockets together to rejoin the ring).

When putting the wires under the floorboards are there any preferences with
repect to how I should route it? Currently all the wiring appears to go
into channels cut into the joists between the nails! I can now see how some
people can put nails through such wiring. Anyway, to avoid me having to
take up more floorboards than I may need to, what is the opinion of drilling
a hole through a joist and running a wire through that? I realise that this
will stop me from being able to move the wires around once all the boards
are up (whereas in channels they can just be layed down - possibly done that
way for ease of installation) - but realistically, when's that going to
happen?

Thanks.
