As shown in the illustrated one-line diagram of a two-tiered emergency power system for a passenger ship, what statement is true? Illustration EL-0166

Correct Answer: Option A — On a restoration of normal ship's power, the final and temporary emergency loads power source is from the main switchboard.

Upon restoration of normal ship's service power, the main switchboard automatically resumes supplying all temporary and final emergency loads, transitioning the distribution system back to its primary power source per SOLAS and 46 CFR.
