Feeders

Definition

Feeders are conductors that carry electric power from the service equipment (or generator switchboard) to the overcurrent devices for groups of branch circuits or load centers supplying various loads.

Purpose

The purpose of Feeders is to transmit electrical power from the main service panel or generator to distribution panels, where the power is then divided into branch circuits for use in different parts of a building or facility.

Examples of Use

• Building Power Distribution: Running feeders from the main electrical room to subpanels on different floors.
• Industrial Plants: Distributing power from a central generator to various production areas and equipment.
• Residential Complexes: Carrying power from the main service entry to individual apartment units.

Related Terms

• Branch Circuit: The portion of a wiring system that extends from the final overcurrent protection device to the outlets.
• Main Service Panel: The central panel that distributes electricity to different circuits in a building.
• Load Center: A distribution panel that divides electrical power into subsidiary circuits.

Notes

• Feeders can be installed underground or overhead, depending on the building's design and requirements.
• Proper sizing and protection of feeders are essential to ensure safety and prevent electrical overloads.
