If phase sequence is ABC (counterclockwise), what is the rotation for sequence BAC?

Explanation:
The order of the three phase voltages determines the direction of rotation. If the sequence is A → B → C, the voltages appear to rotate counterclockwise. Reordering to B → A → C flips the order, which reverses the rotation direction. Swapping two phases reverses the rotation, so the sequence BAC corresponds to clockwise rotation.
