Which of the following describes a "feeder" in electrical distribution?

A "feeder" in electrical distribution refers to a circuit that connects the service equipment, such as a main panel or switchgear, to the branch circuits that supply power to individual outlets, lighting fixtures, and appliances. This definition emphasizes the feeder's role as an intermediary that carries electrical power from the service equipment to various branch circuits throughout a building or facility.

The feeder is essential in ensuring that electrical distribution is organized and that power is effectively managed as it reaches the end users. It typically handles a higher load than branch circuits because it serves multiple circuits downstream. The distinction of the feeder is that it does not directly supply power to end-use devices; instead, it acts as a distribution backbone within the electrical system.

Other options describe different components or systems that do not align with the specific definition of a feeder. For instance, a circuit that is primarily for lighting refers to branch circuits rather than feeders, while a protective device for switching does not relate to feeders but rather to circuit protection and control. A load management system involves techniques and tools to monitor and adjust electrical loads, which is also outside the scope of what a feeder is.
