In electrical systems, what are feeders?

Feeders are defined as the conductors that connect the main electrical service to the branch circuits. They play a crucial role in distributing electrical power safely and efficiently throughout a building or facility. By serving as the pathway that conveys power from the main service to various branch circuits, feeders are designed to carry the electrical load required by those circuits.

In the context of electrical systems, feeders must be properly sized to handle the total load they are intended to supply. This requires consideration of various factors, including amperage, voltage drop, and the types of loads being served. Understanding feeders is essential for ensuring a balanced and safe distribution of electricity, which ultimately supports the operation of all equipment and systems connected to those branch circuits.

The other options describe different components or functions within electrical systems but do not accurately convey the specific role of feeders. Storage devices, safety devices, and transformers all serve important purposes, but they are distinct from the role that feeders play in the electrical distribution network.
