In the illustration of the one line distribution system 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 B — It will automatically start and automatically supply power to the 450 VAC section of the emergency bus through the automatic bus transfer device.

Upon a main power failure, SOLAS and 46 CFR Subchapter J regulations dictate that the emergency diesel generator must automatically start and assume emergency bus loads via an automatic bus transfer device, ensuring vital shipboard services are restored within mandatory time limits without manual switching.
