This is a valid consideration with regard to safety.
Given a 6-amp maximum, 0.75 sq mm size, and 2 meters
length.
In North America, 2X rated current is the 1-minute
operating time

I am curious as to the hazard that is prevented by

For an IT product there is a restriction in the use of mains cords with a cross
sectional area of 0.75mm2 for units up to 6 amps when the cord is greater than
2m in length (EN60950: 2000 section 3.2.5)
Can anyone tell me is there is a requirement (in any standard) specifying a
maximum fuse rat
