Correct Answer: Option A — the feeder disconnect contactor remains closed on a loss of power

Feeder disconnect contactors of this type are engineered to hold closed under normal conditions and remain shut during momentary power loss or dips, ensuring essential distribution paths stay intact until manual intervention or specific fault tripping occurs.
