Marine Electrical Systems USCG Question #27 (Set 1)

Which statement is true concerning a split-phase induction motor?

Official USCG Answer & Rule Citation

Correct Answer: Option B — Motor rotation can be reversed by reversing the leads on the starting winding.

Rotation in a split-phase induction motor is determined by the phase relationship between the main and auxiliary windings. By reversing the connections of the starting (auxiliary) winding, the phase shift relative to the main winding is inverted, which changes the direction of the rotating magnetic field and the motor.
