Cross phasing refers to which of the following situations?

Cross phasing refers to which of the following situations?

• A. When phases are mixed around by accident
• B. When phases are rotated in correct order
• C. When only one phase is energized
• D. When voltage magnitude increases

Answer: (A)

Cross phasing is when the three-phase conductors are connected in the wrong order, swapping two phases so the phase sequence is incorrect. This accidental mix-up changes the rotating magnetic field in machines, which can cause motors to run in the opposite direction or operate poorly and with more stress. It’s not about rotating phases in the correct order, energizing only one phase, or simply increasing voltage magnitude.
