Feeder

In Plain English

The heavy-duty wires that carry power from the main electrical panel to a sub-panel or large piece of equipment.

Definition

The conductors between the service equipment and the final branch-circuit overcurrent protection device. Feeders distribute power from the main service panel to sub-panels, large equipment, or other distribution points. Feeder size is determined by the calculated load and voltage drop requirements.

Example

A 400-amp feeder was run from the main service to the tenant sub-panel in the new commercial suite.
