To determine

Identify why and which voltage must be used for the dual voltage motor to be used for part winding starting.

Expert Solution & Answer
Check Mark

Explanation of Solution

If a dual voltage 240/480V motor is used for a part winding starting, then the low voltage setting must be used. This is because, since only one winding is connected to the power line, the high current due to high voltage supplied causes overheating of the windings.

Hence, 240V must be used for part winding starting.
