What should be the response when an ABT switches to the alternate feeder?

When an Automated Bus Transfer (ABT) switches to the alternate feeder, the most appropriate response is to perform a system check. This action is crucial because the switching between feeders indicates a change in the power source that could potentially impact the functionality and stability of the electrical system. A system check ensures that all equipment is functioning correctly and that there are no issues resulting from the transition, such as power quality problems, voltage fluctuations, or connectivity issues.

Conducting a system check helps verify that the alternate feeder is supplying power appropriately and confirms that all protective systems are operational, which is vital for maintaining safety and reliability in power distribution. This proactive approach minimizes the risk of equipment failure or operating anomalies that could arise from unexpected changes in power sources.
