Article 215: Feeders - EC&M
Jun 1, 2007 · The main difference is that a feeder runs between an overcurrent protection device (OCPD) at the supply and a downstream OCPD (typically supplying a branch circuit), while a branch circuit runs between an OCPD and an outlet (or final load). In other words, a feeder supplies power to a branch-circuit OCPD — which, in turn, powers a branch circuit.
Article 215
Feb 28, 2021 · This article covers the installation requirements, overcurrent protection requirements, minimum size, and ampacity of conductors for feeders.Exception: Feeders for electrolytic cells as covered in 668.3 (C) (1) and (C) (4). Minimum Rating and Size. Feeders Not More Than 600 Volts. General.
215.2(A)(1) Feeders. Minimum Rating and Size.
The minimum feeder-circuit conductor size, before the application of any adjustment or correction factors, shall have an allowable ampacity not less than the noncontinuous load plus 125 percent of the continuous load.
Feeder Conductors - Article 215 , based on the 2017 NEC - Mike Holt
The NEC provides the minimum size a feeder must be. It also recommends upsizing your conductors for voltage drop. But there are many other factors to consider for a successful feeder installation, including selecting an insulation appropriate for the application and environment.

Feb 1, 2018 · 215.12(C)(2) Direct-Current Feeder Identification Methods. With the exception of high-leg systems and isolated power systems, the NEC does not require specific colors to identify ungrounded AC conductors.
Article 215 Feeders - NFPA 70 - National Electrical Code
Article 215 contains the requirements for feeders not over 1000 volts ac or 1500 volts dc, nominal. The removal of the medium voltage feeder requirements happened during the 2023 NFPA 70 cycle. The medium voltage requirements can be found in Article 235.
NEC Article 215: Feeders (Sections 215.1 to 215.18)
NEC Article 215 provides comprehensive guidelines for the installation and protection of feeders, ensuring they are safe, reliable, and capable of supplying the necessary power to distribution points within a building.
8 NEC Basic Feeder Circuit Sizing Requirements
Dec 17, 2014 · As this article only presents the basic NEC requirements for load calculations, it is imperative to refer to the NEC itself when in doubt about a specific load sizing application. Computer programs are commercially available to automate the calculation of feeder and branch circuit loads per the NEC methodology described above.
215.2(A)(1) Feeders. Minimum Rating and Size.
Jan 25, 2024 · For complete code sections, refer to the actual NEC ® text at NFPA.ORG. Once there, click on their link to free access to the 2020 NEC ® edition of NFPA 70. 2020 Code Language: 215.2(A)(1) General. Feeder conductors shall have an ampacity not less than the larger of 215.2(A)(1)(a) or (A)(1)(b) and shall comply with 110.14(C).
215.2(A)(1) Feeders. Minimum Rating and Size.
Feeder conductors shall have an ampacity not less than required to supply the load as calculated in Parts III, IV, and V of Article 220. Conductors shall be sized to carry not less than the larger of 215.2(A)(1)(a) or (b).
