I just put a clamp-on ammeter on each of the 3 wires coming from the RPC to the lathe to see how much current was flowing. Two of the wires read 6 amps and the third wire read 2.2 amps. The 2HP motor nameplate says 6.2 amps at 230 volts. I assume that 6.2 number would be at maximum load, but the lathe was just running and I wasn't doing any cutting. What's the story here? I would think that all 3 wires would be carrying the same amount of current, and it would be lower than the maximum of 6.2. Do I have some kind of problem here or is this the nature of a RPC? By the way, I tested the ammeter on a 75 watt light bulb and it showed 0.6 amps and the calculated value was 0.64 amps so it seems that the ammeter works.
