This is the next to useless number I mentioned in my post. It is the
theoretical maximum amount based on the theoretical voltage. In the
field, voltage can vary and so can the usage. I know it sounds nutty,
but I've seen variations of more than 15% from the theory and that, to
me, is unacceptable.
If +/- 15 % is unacceptable then the clamp on ampmeter you suggested
from Harbor Freight would also be unacceptable.
Don't assume. Buy it and test it like I did. The lab said +-3%. I
consider that to be acceptable. If you don't like those numbers, then
buy one for $300 and compare it to what you suggest the "book" numbers are.
