In an electrical system, what do "feeders" refer to?

• A. Wires that connect branch circuits to outlets
• B. Conductors that carry power from service equipment to sub-panels
• C. Cables designed for residential lighting
• D. Electrical devices that reduce voltage

Answer: (B)

Feeders refer to conductors that transport electrical power from the main service equipment, such as a transformer or main panel, to sub-panels throughout a building or facility. They are crucial in the distribution of electricity as they effectively manage and carry higher amperage loads necessary for powering various systems in different areas. Understanding this concept is vital because feeders are designed to handle the voltage and current requirements of sub-panels, ensuring that electrical distribution is efficient and safe. In contrast, the other options describe different components within an electrical system but do not align with the specific function of feeders. For example, while branch circuits connect outlets to the wiring system, they are not the main transport conductors like feeders. Cables for residential lighting and devices that reduce voltage serve very different purposes and do not reflect the primary role that feeders play in the electrical layout.
