All in all, the basic installation schemes are very similar now though.

The ring circuit, plug fusing polarisation and earth is a fudamentally
different approach to safety to those used in most of Europe. Thats one
of the reasons Britain remains at odds with most of europe on
electrical wiring methods and standards.

Yes


Europe uses primarily non polarised sockets with unearthed appliances,

No - the proposed new standard socket had an earth pin so it was polarised
if you used the correct plug.


and unfused plugs relying of distribution board fusing, double
insulation and many circuits to avoid nuisance overload trips. This is
why they tend to assume our 30A rings are dangerously fused, and that
putting 50 sockets on one feed is potentially lethal.

Proposal was to move the trips to the room - a mini-CU in each room as I
mentioned, thereby cutting down on the km of cable needed.
