Question 31Electricity & Electronics - 1st Asst/Chief

The correct answer is C) the generator circuit breaker from the bus. A bus disconnect link is used to isolate the generator circuit breaker from the bus. This allows the generator circuit breaker to be serviced or maintained without disrupting the electrical system. By isolating the generator circuit breaker from the bus, the rest of the electrical system can continue to function while work is performed on the circuit breaker. The other options are incorrect because they do not accurately describe the purpose of a bus disconnect link. Options A, B, and D describe isolating other electrical components or systems, which is not the primary function of a bus disconnect link.
