Put it another way: you're responsible, and want to get the machine
both working and working safely. The fuse selection isn't a 'legal'
decision, it's a technical one. You'll use technical data, judgement,
and take technical advice.

The 'correct' value fuse can't be critically important, if its failure
spewed
bits of metal in all directions the first time it interrupted the
circuit...
and you still want the machine back into operation.
