Terms related to the distribution system

Feeder, distributor, and service mains are all parts of an electrical distribution system that connect substations to consumer terminals:

• Feeder: A conductor that connects a substation to an area where power is distributed. Feeders are designed to carry large amounts of current and transmit electricity over long distances.
• Distributor: A conductor that supplies power to consumers by taking taps. When designing a distributor, the main consideration is voltage drop along its length.
• Service mains: Service mains are the shortest conductors in length in a power distribution system. They connect the distributor (local power lines) to the consumer's premises, such as houses or buildings.
