Yes Gary,
I agree,. Which is why the English 240V 13amp plug has a replaceable fuse
built into the plug to protect the individual appliance.

I disagree. The nec is only concerned about the wire between the breaker and
outlet being protected. You can readily plug in a computer for example that
has only #18 wire in its power cord. Surely the 20 amp breaker in the power
panel is not expected to protect that #18 computer cord.
If they were concerned about anything further they would require a smaller
fuse at the outlet where the computer was plugged into or require #12 power
cord to the computer.
