What does the term "feeder" signify in a schematic?

The term "feeder" refers specifically to a conductor or group of conductors that carry electrical power from a service point, such as a main panel, to a subpanel or distribution point. This definition is crucial in electrical schematics as it signifies the pathway for electrical energy to reach various parts of a building or facility, ensuring that subpanels and other distribution points receive the necessary voltage and current to function properly.

In the context of electrical design and distribution, understanding the role of feeders is essential for safe and efficient electrical installation. A feeder is designed to handle specific loads and is rated for the total current it is expected to carry, which is vital for ensuring the overall safety and compliance with electrical codes.

Other options do not define "feeder" accurately within the context of electrical schematics. For instance, conduits for data cables, protective devices, and measurements of electrical load pertain to different aspects of electrical and data distribution and do not embody the specific role of a feeder conductor in delivering power. This clarity helps in interpreting schematics and executing proper electrical installations.
