Question 246Electricity/Electronics - Assistant Engineer70% to pass
There are very specific rules that govern the testing of generators found in the appropriate publication incorporated by reference. According to 46 CFR, Subchapter J (Electrical Engineering), which agency publishes the rules for the construction and testing of generators?
AI Explanation
The correct answer is B) American Bureau of Shipping.
According to 46 CFR Subchapter J (Electrical Engineering), the rules for the construction and testing of generators are published by the American Bureau of Shipping (ABS). The ABS is a well-known classification society that sets standards for the design, construction, and maintenance of various types of vessels, including those used by the US Coast Guard. The regulations in Subchapter J specifically reference the ABS rules as the applicable standards for generator design and testing.
The other options are incorrect because ASME (American Society of Mechanical Engineers) does not publish the rules for generator testing, the manufacturer's own standards are not the regulatory requirements, and Underwriter's Laboratories, Inc. is not the agency specified in the regulations.
