You are in the planning stages of setting the longtime over current trip of a ship's service generator circuit breaker. According to 46 CFR, Subchapter J (Electrical Engineering), what statement is true regarding the criteria for the longtime over current trip set point, assuming the generator is capable of being paralleled?

Correct Answer: Option B — The trip point should not be larger than 115% of the generator rating for a continuous rated machine.

Under 46 CFR Subchapter J, continuous-rated parallelable generators require longtime overcurrent trip settings capped at a maximum of 115% of the machine's continuous current rating to protect windings.
