Hello,
I have some 220V tools that I need to run from 110V through a
Maxwell is correct. All US electrical services have 220V available.
All you need to do is install a 2 pole breaker to get 220V. If you
really only have 110V available, then the KVA rating is what you
should use. Remember that it is the load current that causes I^2R
heating in the transformer. Also, breakers respond to current, not
power. So 3000/110 = 27.3A is the prper rating to use. This is not a
standard size. You probably are safe with a 30A breaker.
Just keep in mind that the NEC specifies you can only load a breaker to 80%
of its rating. 30A * 80%= 24A Max.
