Hi Robert,

I would expect a 15/120 system like yours to draw 30+ amps without PFC and 
17+ amps with say 400uF of PFC capacitance.  If it is not tuned well, it 
could pull much more.  I would try to tune at far lower power using a wire 
to get breakout if needed.  Once it is tuned you should be able to turn it 
up higher.  You may need another 200+ of PFC capacitance too.  Be sure 
there is nothing else on the circuit and that the breaker is in good 
condition.  Damaged breakers tend to trip way too soon.  If you have a sync 
rotary gap, the motor may draw about 5 amps too.  So I think you can do it 
on 20 amps, but it is sort of close.

Cheers,

         Terry
