You seem to have a bizzare fixation on one issue which
is pretty much a non-sequitur, whilst still failing to
understand the safety features designed into the system
as a whole.

Bare in mind the BS1363 plugs and sockets and the ring
circuit is the most recently designed power distribution
system for portable appliances in the world (that I know
of anyway), and sought to avoid all the problems the
pre-existing systems had, and didn't compromise itself
by trying to be backwards compatible with anything that
came before (unlike most other power distribution systems
in use today). Its safety speaks for itself when compared
to other systems in the world. I won't pretend it has no
issues or it could not be improved -- there have been a
number of improvements through its nearly 60 year life.

When was it universally adopted? I think the 1960s. Rings are "not"
mandatory. Many are going to radials as rings create magnetic fields around
a house. Many people are susceptible to this. Radials avoid the problem
