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? Illustration EL-0014

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

Under 46 CFR Subchapter J, upon main power failure, the emergency generator starts automatically and uses an automatic bus transfer (ABT) device to instantly restore power to essential 450 VAC emergency loads.
