Question 1955 Deck General

The correct answer is C) The dead-front type, totally enclosed. The small passenger vessel regulations specify that switchboards must be of the dead-front type, which means the current-carrying parts are enclosed to prevent accidental contact. This ensures the switchboard is totally enclosed, protecting crew and passengers from potential electrical hazards. The other answer choices are incorrect because: A) switch locks are not required, B) switchboards do not need to be watertight, and D) grounding to the main engine is not a requirement for switchboards on small passenger vessels.
