Another very important difference between UK practice and North American 
practice is that in the UK, ring circuits are used, while they are not 
in the US. The central breaker panel in a typical home will have 15-30 
branch circuits that go to various parts of the home. The breakers are 
set for 15A or 20A, and are carried on #14 or #12 copper with a phase, a 
neutral, and a protective earth.

There's a FAR more extensive description of power wiring practices both 
in the US and Europe on my website that I was paid to write by a company 
that makes power protection products..  The did NOT tell me WHAT to 
write.  :)
