National Electrical Code Tips: Article 215, Feeder Circuits

Please note, we do quote from copyrighted material. While the NFPA does allow such quotes, it does so only for the purposes of education regarding the National Electrical Code. This article is not a substitute for the NEC.

One thing that jumps right out to people studying the NEC is that Article 215 is  very short. This is surprising to people who've just studied Article 210, Branch Circuits, and are moving on to the next logical step.

You might be thinking feeders are just a heavy version of branch circuits, so Article 215 should just be Article 210 on steroids. But, don't think that way because "it aint so."

Article 210 covers many permutations of branch circuits, and devotes extensive text to dwelling area branch circuits. Dwelling areas don’t have feeder circuits.

Here’s an object lesson in the value of Article 100. Go there now and review the definitions of branch circuit and feeder circuit. Once you’ve done that, you will understand why Article 215 is so much shorter than Article 210.

How the NEC is arranged

  1. The first four Chapters of the NEC apply to all installations.
  2. Article 90 precedes Chapter One, and establishes the authority of the NEC.
  3. Article 80 follows the body of the NEC; it exists as Annex H. It provides the requirements for administration.
  4. Chapters 5, 6, and 7 are the "special" chapters, covering special: occupancies, equipment, and conditions (in that order).
  5. Chapter 8 provides the requirements for communications systems.
  6. Chapter 9 provides tables.
  7. The appendices provide mostly reference information.
  8. Appendix D contains examples that every NEC user should study.
