It is now many years since I passed my City & Guilds 224, 232 and 236 and I
don't pretend to be up to date with the Regs.

However, a young upstart :-) son of a friend is currently training as a
sparky at a local hospital. He tells me that it is now acceptable to run as
many spurs off spurs as you like provided that all the outlets are in the
same room. I was very sceptical that this was the case (although being New
Year we had all had several shandies) and wonder if any of the learned gents
on this site can reassure me?

I presume it is also still the case that you must not have more spurs than
ringed outlets on a ring main? If I have got sufficiently out of date to
have missed both of these fundamental changes I fear it's the end of the
world as I know it!

I do remember at college being given earache for calling a ring final
sub-circuit a ring main, and for calling MIMS by the usual name (to me) of
Pyro! I was forcibly lectured that you only ever found a ring main as part
of the supply network operated by the electricity board as it was then.
