As there is NO wording within 110.24 requiring any identification of the person/entity creating the label, or doing the calcs, how do you see one of our abundanance of lawyers coming after you, or any other individual?
There isn't even any requirement to what values need to be put on the label.
An actually calculated value? - This is the hardest value to get, and i will change with time.
A maximum design value? - Some utilities provide this value to aid in selecting equipment ratings.
A minimum equipment rating value? - Some engineers base their AIC selection off of voltage levels without considering real world conditions.
I calculate a service as being 480V 24,850A.
The utility says they will never exceed 50,000A
The plans call for a minimum 65kAIC equipment at 480V
