Final answer:
Before removing a generator that is underperforming, it is crucial to check the control, feeder, and regulator circuits to determine if there is a correctable issue within these systems.
Step-by-step explanation:
If a generator is not delivering its rated voltage or current, it is important to check each of the following circuits before removing the generator:
- Control circuit, to ensure that the commands to the generator are being given correctly.
- Feeder circuit, which is responsible for carrying the power from the generator to the load.
- Regulator circuit, which stabilizes the voltage and current output of the generator.
By examining each of these circuits, one can often identify and correct the issue without the need to remove the generator.
