Question 361General Subjects - 1st Asst/Chief
70% to passCoast Guard electrical engineering regulations specify capacity ratings for electrical equipment. Based on the inspection of the cables on one of your ship's service generators, you've decided that the cables need to be replaced. The current-carrying capacity of the replacement generator cables should be what percent of the continuous generator rating?
ALess than 15 percent
BLess than 100 percent
CLess than 115 percent
DLess than 220 percent
AI Explanation
The correct answer is C) Less than 115 percent. The Coast Guard's electrical engineering regulations specify that the current-carrying capacity of electrical cables should be at least 115% of the continuous generator rating. This ensures that the cables can safely handle the full output of the generator without being overloaded. Cables rated at less than 115% of the generator capacity would be undersized and could potentially overheat or fail under normal operating conditions. The other answer options are incorrect because they do not meet the 115% requirement set forth in the regulations. Less than 15% or 100% would be too low, while less than 220% would be excessively over-sized.
