In the illustrated one line diagram, if the ship's service generator on line fails, what statement is true concerning the operation of the emergency diesel generator? EL-0014

Correct Answer: Option C — It will automatically start and automatically supply power to the 450 VAC section of the emergency bus through the automatic bus transfer device.

Upon loss of the main ship's service generator, regulatory marine power distribution standards dictate that the emergency diesel generator automatically starts and feeds the emergency bus through an automatic bus transfer (ABT) device to maintain vital safety services.
