Question 568Electricity & Electronics - Assistant Engineer

The correct answer is B) Sewage Treatment Plant. The sewage treatment plant on a vessel is typically supplied with a circuit breaker that provides both overload and short-circuit protection. This is a safety requirement to ensure the electrical system powering the sewage treatment plant is properly protected against electrical faults, which can prevent damage to the equipment and potential safety hazards. The other options, such as the lube oil service pump, cargo oil transfer pump, and seawater cooling circulation pump, may also have circuit breakers, but they may not necessarily provide both overload and short-circuit protection, which is the specific requirement being tested in this question.
