Proper feeder sizing helps prevent overheating and ensures that the electrical system operates effectively. Feeder conductors shall have an A feeder line is a peripheral route or branch in a network, which connects smaller or more remote nodes with a route or branch carrying heavier traffic. This article covers the installation requirements, overcurrent protection requirements, minimum size, and ampacity of conductors for feeders supplying branch-circuit loads. Article 225 contains the installation requirements for outside branch circuits and feeders run on or between buildings, structures, or poles. In radio engineering, a feeder connects radio equipment to an antenna, usually open wire (air-insulated wire line) or twin-lead from a shortwave transmitter. The conductors between the utility service point and the service disconnecting means are service conductors, not feeder conductors. The main function of a feeder is to ‘feed’ electricity to different parts of an electrical system.

(1) General. The Sizing of Feeder Conductors with Protection Supplying from Main Panel to the Subpanel or Branch Circuits Feeder Conductors According to NEC 100 – Definitions, feeders are all circuit conductors between the service equipment (main panel), the source of a separately derived system, or other power supply source and the final branch-circuit overcurrent device (OPCD). (a) Feeders Not More Than 600 Volts. The main feeder is the three-phase backbone of the circuit, which is often called the mains or mainline. Apr 8, 2024 · What Is A Feeder In Electrical Systems? A feeder is a type of electrical line or wire that carries power from a main distribution point, such as a substation, to smaller distribution points or to the end-users. The mainline is normally a modestly large conductor such as a 500- or 750-kcmil aluminum conductor. 6 (A) (1)], as shown in Fig. . In power engineering, a feeder line is part of an electric distribution network, usually a radial circuit of intermediate voltage. 1. 1 Scope. 15. 2 Minimum Rating and Size.
