About Lesson

Article 215 of the National Electrical Code (NEC) covers the requirements for feeders, which are the circuits that supply power from the service equipment to the branch circuits in a building. In this lesson, we will discuss the key requirements of Article 215.

  1. General Requirements Article 215 establishes general requirements for feeders, including their capacity, overcurrent protection, and wiring methods. It also covers the installation of feeders in various types of spaces, such as dwelling units, commercial buildings, and hazardous locations.

  2. Feeder Ratings Feeder circuits must be rated to carry the current required by the connected loads, and their overcurrent protection must be selected to protect the conductors from overloading and short circuits. The rating of a feeder circuit is based on the ampacity of the circuit conductors.

  3. Feeder Wiring Methods Article 215 specifies the wiring methods that are permitted for feeder circuits, including nonmetallic-sheathed cable, armored cable, and conduit. The wiring methods must be appropriate for the location and conditions of use, and must comply with the requirements for ampacity, conductor sizing, and grounding.

  4. Feeder Overcurrent Protection Feeder circuits must be protected by overcurrent devices, such as fuses or circuit breakers, that are rated to protect the conductors from overloading and short circuits. The overcurrent protection must be coordinated with the protection devices on the branch circuits, and must be selected based on the ampacity of the feeder conductors.

  5. Feeder Taps Article 215 permits the installation of feeder taps, which are short sections of feeder conductors that are connected to the main feeder and supply power to a load. Feeder taps must be installed in accordance with specific requirements, including those for ampacity, length, and protection.
