In the lighting distribution circuit shown in the illustrated lighting panel L110 of the illustration, if all circuit breakers are closed and due to a problem with the relevant feeder circuit breaker, there is a loss of power on the incoming phase A, which of the following statements is true? Illustration EL-0013

Correct Answer: Option C — Half of the accommodation lighting circuits on the 01 deck, port side would lose power.

Marine lighting distribution panels split phase loads across alternating buses. Losing incoming phase A on the primary feeder drops power to exactly half of the designated accommodation lighting circuits on the affected port side deck.
