From the information given in the illustration, which of the following statements is correct? EL-0106

Correct Answer: Option A — It is normally the case where the main-emergency bus-tie circuit breaker and any on-line ship's service generator circuit breakers be simultaneously closed.

Interlocking logic prevents parallel connection of independent power sources unless properly synchronized. Therefore, safety interlocks normally permit the main-emergency bus-tie and on-line ship's service generator breakers to be simultaneously closed during normal operations.
