By what means is a diesel-driven emergency generator prevented from being paralleled with the ship's service generators?
AI Explanation
The correct answer is C) an electrical interlock system.
An electrical interlock system prevents the diesel-driven emergency generator from being paralleled with the ship's service generators. This is a regulatory requirement to ensure the two generator systems remain independent and prevent any potential issues that could arise from paralleling them, such as load sharing or back-feeding. The interlock system physically disconnects or blocks the emergency generator from being connected to the main electrical distribution, ensuring it remains isolated and ready for emergency use only. The other options, while related to generator operations, do not specifically address the regulatory requirement for an interlock system to prevent paralleling of the emergency generator.
