You won't get a adequate fault current through too many cascaded

Plug fuses are available in 2A 3A 5A 7A 10A & 13A rating. Fitting the
correct one to leads is hardly self defeating, it prevents fires.

I'd be surprised if you found devices around with as many cable sizes as
that in use these days.

And as regards protecting the device itself, you may need a more specific
type of fuse, like fast blow or whatever.
