Is there any way to test a breaker?

True, but he needs 12/3 plus ground to go with the higher voltage to the power outlet being used (or directly to the compressor).


I'm guessing it's this with a 20 amp breaker.
12/2 with ground.
Upgrading to 230 it should be fine.
The motor will actually pull less.
(I know. Romex is like Kleenex. It was easy to pull up)
