What is referred to as a "Feeder" in electrical systems?

In electrical systems, a "Feeder" is understood as all the circuit conductors that connect the service equipment to the final branch-circuit overcurrent device. This encompasses the wiring and infrastructure that carries electrical power from the main service panel to branch circuits, effectively distributing electricity to various parts of a building or facility.

This definition is critical because feeders are designed to handle larger loads than branch circuits and are an integral part of the electrical distribution system. They ensure that adequate power is supplied to various areas while maintaining safety and operational efficiency.

The other options do not accurately capture the definition of a feeder. While the first option discusses circuit conductors from power sources to consumer devices, it describes transmission rather than the specific role of feeders in distribution. The third option talks about a protective device that prevents overload, which is a protective measure rather than a definition of feeders. Lastly, the fourth option refers to a type of branching circuit but does not align with the functions and characteristics specifically associated with feeders in the electrical system hierarchy. Thus, option B correctly identifies the scope and role of feeders in electrical distribution.
