Attempting to parallel an AC generator which is out of phase with the bus will result in which of the following conditions?

Correct Answer: Option D — The alternator breaker should trip.

Paralleling out-of-phase AC generators creates severe phase angle differences and massive transient current spikes, triggering instantaneous overcurrent and reverse-power protective relays to trip the incoming breaker, protecting switchboard integrity per 46 CFR Subchapter J standards.
