They

protection above. I agree with them. I know some people who

That is one of the many failing with ring circuits I've tried to
illustrate, but the IEEE 'dinosaurs' just can't see the wood for
the
trees....

The only way you'd 'improve' on this would be to have one radial
circuit
per socket with its own MCB.

No, there is no need for one socket per radial, what *is required*
are the MCB's (which is far more difficult to circumvent), in these
days of low wattage appliances you could easily have two if not three
sockets per radial without load problems - how many people use more
than one Kew fire in a room anyway (any such load would have extra
provision made even now in many homes, even with ring circuits) ?...


Total madness and completely unnecessary.

You seem to thing plug fuses blow regularly. I can't honestly think
of the
last time I had to replace one which has failed for no reason. And
if an
appliance has a fault, that fault has to be corrected anyway, so it
makes
little difference if the fuse is in the plug, the appliance itself
or non
at all but simply an MCB.


It's not just about fuses blowing, it people using the wrong fuse,
for example protecting a table lamp with a 13A fuse, when the lamp
should / could be on a lighting circuit. What I'm trying to get over
is that there is (IMO) the need to remove the user from the direct
supervision of the appliances final protection. Sealed MCB's / RCD's
back at a distro' board allows that, this was not an option back in
the 1940/50's.

You seem to be happy that someone can protect a single 40W light bulb
stand and meters of such rated cable @ 13A (or more, if the *user*
wishes and does something totally idiotic) with little or no
thought - far enough...
