I have installed a 15 HP unit good for 53 Amps.
The unit is installed to convert 240-V single-phase to three-phase to run a 15 HP, 3200-RPM, three-phase electric motor @ 3200 RPM. When I start the motor, I get 28 Amps on L1, 28 Amps on L2 and 48 Amps on L3.
Why do I get the phase imbalance? How can I get the same amps on each leg?
