Question 292Electricity & Electronics - Assistant Engineer
70% to passWhen electrical cables penetrate watertight bulkheads, what must be provided for?
Acables should be grounded on either side of the bulkhead
Ba watertight stuffing tube capable of accepting packing should be employed
Ccables must be bent to a radius of six diameters
Dcables should be secured by a clamp
AI Explanation
The correct answer is B) a watertight stuffing tube capable of accepting packing should be employed. When electrical cables penetrate watertight bulkheads, a watertight stuffing tube must be used to maintain the integrity of the bulkhead. This is a requirement specified in maritime regulations to ensure that water cannot pass through the bulkhead along the cable path, which could compromise the watertight compartmentalization of the vessel. The other answer choices are incorrect as they do not address the specific need for a watertight stuffing tube in this scenario.
