Dear Bostjan:
One of the uses of current rating on equipment is to determine that the
equipment, with all of the other equipment, would not overload the mains
circuit. If the actual current exceeds the marked current, then the equipment,
with all of the other equipment, can overload the mains

Thank you. But for example if I measure 10% more than rated, it is
still pass by the standard and I test only one sample. So in real
production it can be more than 110% considering tolerances.

Does anyone know what is behind the requirement, that measured input

come from?
It's an estimate of the variation in actual input current

Hi Bostjan!
I had heard (and perhaps this is apocryphal) that the 10% was intended to allow
for manufacturing tolerances in the final product. I don't know how the number
was arrived at.

Dear experts,
Does anyone know what is behind the requirement, that measured input current of
the unit can exceed the rated current by 10%? Where this 10% come from?
Best regards,
