The green wire goes to green. The red wire goes to red. But the two black line wires.....if I get them reversed is the only ill effect that the motor runs backwards and I can simply reverse them?
Also.....I'm using single phase 240 V to power up a rotary phase converter to run it. The meat saw motor is 2Hp 3 phase. The rotary phase converter has a 3Hp, 3 phase, 15 amp output, so that's good, but what size of circuit breaker should I use in the breaker box? 20amp? 30 amp? I don't know how many amps I lose in the conversion to 3 phase.

6 years of engineer work after school, with a not so stellar GPA. I plan on pursuing an grad degree, have years of experience but these graduate schools seemingly hinge on GPA only! In the past six years I have acquired a wealth of knowledge beyond any recent graduate with a 4.0 GPA. does this not account for anything?

I mean, I know how an air conditioner works. But it seems like the colder the whole thing is, it would have to be more efficient. I'm just asking because water is included in my lease but I have to pay for power.
