So? Most appliances will cope with a 13A plug fuse - they have to, to
cope with 16A or 20A radial circuits.

You still seem obsessed with plug fuses. Unlike most radial socket
systems, which evolved from a hodge-podge of accessory designs, the
British ring circuit with fused plugs was *designed* from the outset
to be a coherent and well-engineered system.

What! with at least three different designs of 13A plugs and sockets?
There was a round pin one with a fuse as live pin (very dangerous when
it became detached and stuck out of the socket) and a slot in the earth
pin, and one with two flat pins either side of a hollow circular earth
pin. There may have been others. Hardly coherent!

When last did you see these in a new installation? But inadequately fused
final circuits - to protect appliances etc - are still common round the
world. After all, the maximum fuse on a ring main is 13 amps, while
radials are usually 20 amps.
