The Feeder: Carries power from the main panel to a sub-panel. It feeds the distribution board. No lights, motors, or outlets are directly connected to it. The Branch Circuit: Carries power from the sub-panel directly to the final load (like an induction motor, a lighting fixture . A feeder in electrical distribution is a circuit that carries power from a substation to the area where customers need it. Think of it as the main highway in an electrical network: it moves large amounts of electricity at medium voltage (typically 5 to 35 kV) from a distribution substation outward. Electrical distribution is the final stage in the delivery of electricity to end users. Most share many common characteristics. Figure 1 shows a typical distribution circuit, and Table 1 shows typical parameters of a distribution circuit. The main. multiwire). Branch device and terminates at another circuits are usually low current (30 amps or distribution center, panelboard, or load less), but can also supply high curre ts. A basic branch circuit is made u o the load. Some branch circuits main distribution center and extend to. Feeder lines represent a fundamental part of this hierarchy, acting as the necessary bridge to carry significant amounts of electrical current beyond the main service equipment to secondary distribution points.
