Which of the following best describes what Article 215 of the NEC provides for feeders?

• A. Installation requirements, overcurrent protection requirements, and minimum size and ampacity of conductors
• B. Grounding and bonding requirements only
• C. Cable support and routing guidelines only
• D. Color coding and labeling requirements only

Answer: (A)

Feeder design and safety come from making sure power can be carried to multiple branch circuits without overheating or tripping. Article 215 focuses on how these feeders are installed, protected, and sized. It sets the requirements for how feeders must be run and supported, what overcurrent protection must be used to guard them, and the minimum conductor size and ampacity needed to carry the intended load safely. This combination—installation guidelines, overcurrent protection criteria, and conductor sizing—is exactly what ensures feeders operate reliably and safely.

Grounding and bonding are addressed in a different article, so that’s not the focus here. Likewise, general cable routing or labeling rules are covered in other parts of the NEC, not specifically the core purpose of Article 215.
