Marine Electrical Systems USCG Question #1065 (Set 36)

If deck machinery is expected to be idle for an extended period of time, what should be done?

Official USCG Answer & Rule Citation

Correct Answer: Option A — energize space heaters to prevent the condensation of moisture

Idle deck machinery is highly susceptible to internal condensation due to diurnal temperature swings. Per IEEE 45 and marine engineering standards, internal space heaters must be continuously energized to maintain winding temperatures above the dew point, preventing insulation breakdown.
