What is meant by the term “feeder” in electrical terminology?

The term “feeder” in electrical terminology refers specifically to a set of conductors that carry power to a branch circuit. This means that the feeder acts as the main intermediary between the service entrance and the distribution system of a building, providing the necessary electrical energy to different branch circuits that supply power to various loads, such as lighting and equipment.

In the context of an electrical system, a feeder is crucial because it helps manage and distribute electrical loads efficiently. It typically carries a higher voltage level and larger current compared to branch circuits, which makes it essential for ensuring that sufficient power reaches the specific areas or devices that require electricity.

Understanding the role of feeders is fundamental for electricians, as it relates to load calculations, circuit protection, and overall system design. This ensures that the electrical system operates safely and efficiently without overwhelming any part of the electrical infrastructure.
