In electrical systems, a feeder is specifically defined as a conductor that carries electricity from the service equipment to a branch panel. This critical component plays a significant role in the distribution of electrical power throughout a building, ensuring that the electrical energy supplied by the service entrance is appropriately delivered to the various branch circuits that serve different areas or devices.

The feeder is responsible for carrying the load from the main service equipment, which is typically where power enters a building, to the sub-distribution panels. These branch panels then distribute power to individual circuits that supply specific outlets, lighting, and appliance connections. This role is essential for maintaining an effective and organized distribution of electrical power, allowing for the safe operation of electrical devices across a facility.

Understanding this function helps in grasping the overall structure of residential and commercial electrical systems, as well as in planning and implementing safe and efficient electrical installations.
