We installed a 30A/ 208V/2P circuit for a test bench at a pump testing facility. The controller (provided by the testing facility) we installed can test pumps from 1/2 HP - 5 HP. The pumps are 230V. according to the manufacturer the correct voltage for maximum efficiency should be 230 - 240V and 120V to ground at each leg. We went ahead and installed a buck/ boost transformer to boost the 208V to 240/120V. According to the manufacturer this should be what they are looking for. When they put the pump on the test bench, they are getting an overcurrent of 15A, which is excessive and will burn up the pump. What would cause this overload? Has anyone come across a situation like this? We have tried a variety of different configurations with different sized pumps, all with the same result.
