When checking the voltage or current unbalance of a motor the motor should be ___.

The test for voltage or current unbalance needs the motor to be energized and in operation. When a motor is running, the three-phase voltages and currents should be close to balance; any deviation shows real unbalance that can cause overheating and damage during service. If the motor is shut down or left unloaded, there’s little or no current in the windings, so you would not observe the true unbalance the motor experiences under normal load. Keeping the motor energized (left on) provides a meaningful reading of how evenly the phases are delivering power in actual operating conditions.
