Apr 8, 2024 · 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 main function of a feeder is to ‘feed’ electricity to different parts of an electrical system.
Feb 1, 2018 · A Type SER cable between a 200-amp residential service disconnect and a subpanel is a feeder. The conductors between an 800-amp circuit breaker and a fused branch circuit disconnect supplying a single motor are also feeder conductors.
Jul 21, 2021 · 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. The term is applicable to...
Oct 30, 2022 · A feeder is one of the circuits out of the substation. The main feeder is the three-phase backbone of the circuit, which is often called the mains or mainline. The mainline is normally a modestly large conductor such as a 500- or 750-kcmil aluminum conductor.
Apr 13, 2020 · 1. Radial. Many distribution systems operate using a radial feeder system. A typical radial feeder system is shown schematically in Figure 2. Radial feeders are the simplest and least expensive, both to construct and for their protection system.
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. In power engineering, a feeder line is part of an electric distribution network, usually a radial circuit of intermediate voltage.
Calculation of a service or feeder load, where the feeder serves the total load, for a new restaurant shall be permitted in accordance with Table 2.20.4.9 in lieu of Part 2.20.3. The overload protection of the service conductors shall be in accordance with 2.30.7.1 and 2.40.1.4.
Mar 8, 2022 · This article covers the installation requirements, overcurrent protection requirements, minimum size, and ampacity of conductors for feeders supplying branch-circuit loads. Exception: Feeders for electrolytic cells as covered in 6.68.1.3 (c) (1) and (c) (4).
Oct 2, 2023 · 1. Feeder conductors are thicker than branch circuit conductors. Feeders will have larger current flows compared to those that run a branch circuit so that feeder wires can “feed” branch circuits down the line (this can be seen in a branch circuit single line diagram).
In a radio antenna, the feed line (feedline), or feeder, is the cable or other transmission line that connects the antenna with the radio transmitter or receiver. In a transmitting antenna, it feeds the radio frequency (RF) current from the transmitter to the antenna, where the energy in the current is radiated as radio waves .
