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
AI Explanation
The correct answer is A) On a restoration of normal ship's power, the final and temporary emergency loads power source is from the main switchboard.
This is correct because the one-line diagram shows that the final and temporary emergency loads are both connected to the main switchboard. When normal ship's power is restored, the main switchboard would be the source of power for both the final and temporary emergency loads, as indicated in the diagram.
The other options are incorrect because they do not accurately reflect the power sources shown in the one-line diagram for the restoration of normal ship's power. The diagram clearly shows the main switchboard as the source for both the final and temporary emergency loads.
