What type of circuit provides power to the final overcurrent devices?

The correct answer is feeder because a feeder circuit is designed to deliver electrical power from a distribution point to branch circuits or overcurrent devices. In electrical systems, the feeder circuits typically connect the main power source, such as a transformer or other main distribution equipment, to the different branch circuits or loads that utilize the power. These circuits are important in ensuring that sufficient current can flow through to power all connected devices while maintaining proper overcurrent protection.

In contrast, branch circuits are those that distribute power to specific devices or areas from the feeders. Primary circuits generally refer to circuits that operate at higher voltages and may supply power to transformers or major distribution points, while secondary circuits often refer to low-voltage circuits that provide power to end-user devices after transformation. Thus, the feeder serves as the critical link that provides the necessary power to the final overcurrent devices.
