Question 55Electricity/Electronics - 1st Asst/Chief70% to pass
When electrical cables penetrate watertight bulkheads, what must be provided for?
AI Explanation
The correct answer is D) a watertight stuffing tube capable of accepting packing should be employed.
When electrical cables penetrate watertight bulkheads, the regulations require the use of a watertight stuffing tube to maintain the integrity of the bulkhead. This ensures that water cannot pass through the bulkhead via the cable penetration point. The stuffing tube allows the cable to pass through while providing a watertight seal around it, preventing the ingress of water.
The other options are incorrect because they do not address the specific requirement for a watertight stuffing tube. Securing the cables with a clamp (A), grounding the cables (B), or bending the cables to a specific radius (C) do not directly maintain the watertight integrity of the bulkhead.
