What does a "feeder" refer to in electrical terms?

In electrical terminology, a "feeder" specifically refers to the conductors that transport electricity from the main service panel to sub-panels or load centers. This is a critical role in residential and commercial electrical systems, as feeders ensure that power is distributed effectively to various areas requiring electricity, such as different rooms in a building or specific machinery in an industrial setting.

Feeders are typically designed to handle larger loads compared to branch circuits, which distribute power to individual outlets or fixtures within a more localized area. The proper sizing and installation of feeders are essential for maintaining the efficiency and safety of the electrical system, as they must be capable of handling the total load they are intended to serve without overheating or exceeding their rating.

The other choices do not accurately describe a feeder: large circuit breakers are protective devices, converters handle the change from AC to DC power, and cables for lighting circuits would be classified differently as they serve a more specific function. Understanding the concept of feeders is vital for anyone working in electrical trades, as it is fundamental to the design and operation of electrical distribution systems.
