What component automatically transfers power to an alternate feeder?

The component that automatically transfers power to an alternate feeder is the Automatic Bus Transfer (ABT). This device plays a crucial role in ensuring that power delivery remains uninterrupted during a failure or outage of the primary supply. When the primary feeder experiences an issue, the ABT detects the loss of power and quickly re-routes the electrical supply to an alternate feeder without requiring manual intervention.

This automatic response minimizes downtime for critical systems and ensures continuous power availability, which is especially important in applications where maintaining power is essential for safety or operational integrity. The ability of the ABT to perform this function seamlessly enhances the reliability and efficiency of power distribution systems.

In contrast, the other options involve manual operation, have different functions in power management, or are not specifically designed for automatic switching between feeders. For instance, a power distribution panel organizes and directs the electrical supply but does not manage automatic transfers between power sources. A manual switch requires human action to change the power source, while a generator set provides an alternative power source but does not handle the switching process on its own.
