Schuko outlets were originally spec'ed for 3.5kW (220V).
BS1363 (UK 13A) outlets were originally spec'ed for 3kW (240V).
Now the EU is nominally all 230V, the figures go slightly out,
but as that was a paper change, it makes no difference in practice.
BS1363 plugs are bulkier because they contain a small cartridge
fuse (the supply behind the outlet is designed to provide 30 or 32A,
but that's to much more than one outlet). You are right that the
pins themselves could probably carry 50A continuously without getting
