167. As shown in figures «A», «B», «C», and «D» of the illustration, what is the usual means by which the rotation direction of the motor is reversed

Reversing a motor's rotation direction typically involves reversing the connections of the auxiliary (start) winding, which is achieved by interchanging leads T5 and T8. This isolates the reversal to the start winding while maintaining the main winding's connections, ensuring proper operation and avoiding damage.
