Why would it do that? A three wire feed implies a balanced load, such as a three phase motor, charger or welder supply. Voltage drop is measured line to line and line current is still measured the same way, as are power factor numbers. The only difference in a three phase motor connection is assuring correct direction for motor rotation. Some things break in a dramatic fashion if turned the wrong way. Where does the 120 come from?
