Hah! I sold the UPS because the batteries were getting to the point they 
would be failing and I could never afford to replace them. Then I realized 
how bad the power really was :-)

Yea, the 100 amps x 3 phases was pretty weak. I was playing with laser 
stuff for a while, and I used to pull out the 60 and 50 amp 2 pole air 
conditioning breakers to make room for a 3 pole 30 amp breaker to feed a 
large argon laser:
