Question 262Electricity & Electronics - QMED

The correct answer is B) the generator circuit breaker from the bus. A bus disconnect link is used to isolate the generator circuit breaker from the bus, allowing for maintenance or repairs to be performed on the generator without disrupting the power supply to the rest of the electrical system. This ensures safety and allows for the generator to be serviced independently. The other answer choices are incorrect because they do not accurately describe the primary function of a bus disconnect link, which is to isolate the generator circuit breaker from the bus. Options A, C, and D describe different electrical components or systems that are not the primary purpose of a bus disconnect link.
