No, no, no, no ,no!

The sole purpose of the fuse in the plug is to protect the
flexible cable connected to it and should, therefore, be rated
accordingly.

If you fit a 13A fuse to a plug fitted with flex rated at 3A
and another idiot connects the other end to a 3kW load, what
do you think might happen?

But have you seen anything these days with a 13 amp plug where the flex
would suffer damage with a 13 amp fuse and short circuit?

You certainly used to. Rather like two core IEC leads. But not now.

I hope you knpw where the nearest fire exot is and, of course,
that the overheated cable isn't between you and it ...

Difference between a flex being capable of blowing a fuse in event of a
short and handling 13 amps continuously without overheating.
