What is a common characteristic of feeders in an electrical distribution system?

Feeders in an electrical distribution system serve a crucial role in linking the service entrance of a building to the various branch circuits that supply power to different areas and devices. This characteristic is essential because feeders are designed to carry high levels of current over relatively long distances within a building's electrical infrastructure. They ensure that electrical power is efficiently transported from the main service panel to sub-distribution panels or directly to branch circuits that supply power to outlets, lights, and other loads.

The focus on connecting the service entrance to branch circuits highlights the feeder's responsibility in distributing electricity within the system, making it a foundational component for effective electrical service.
