Question 283Electricity & Electronics - Assistant Engineer

The correct answer is A) the feeder disconnect contactor remains closed on a loss of power. This is because the feeder disconnect contactor is designed to remain closed on a loss of power, which ensures that the connected equipment continues to receive power even in the event of a power failure. This is a key safety feature to prevent disruption of critical systems. The other options are incorrect - B) the feeder disconnect contactor is electrically latched, C) the feeder disconnect contactor is electrically tripped, and D) the feeder disconnect contactor is mechanically closed do not accurately describe the behavior of the feeder disconnect contactor as shown in the illustration.
