A feeder is defined as which of the following?

• A. All Circuit Conductors Between the Service Equipment, the Source of a Separately Derived System, or Other Power Supply Source and the Final Branch Circuit Overcurrent Device
• B. The Conductors That Feed a Single Outlet
• C. The Wiring Inside a Panelboard
• D. The Service Drop Conductors Only

Answer: (A)

In electrical wiring, a feeder is the set of conductors that carries power from the service equipment (or the source of a separately derived system) to the final branch-circuit overcurrent device. This path supplies multiple branch circuits downstream, not just a single outlet or device.

That definition matches the option that describes all conductors between the service equipment (or source) and the final branch-circuit overcurrent device, which is exactly what a feeder is.

The other ideas fit different parts of the system: conductors feeding a single outlet are branch circuits, the wiring inside a panelboard is part of the panel’s internal wiring rather than the feeder itself, and service drop conductors are the utility’s lines delivering power to the service equipment, not the internal feeders feeding the distribution equipment.
