In which article would you find regulations regarding feeders?

The correct choice is based on the specific content covered in different articles of the National Electrical Code (NEC). Regulations related to feeders are primarily found in Article 215. This article covers the requirements for feeder conductors, which are essential for distributing electrical power from the service equipment to the branch circuits. It details aspects such as conductor sizing, installation methods, and other critical parameters to ensure safety and functionality in electrical systems.

The other articles mentioned focus on different subjects. Article 110 deals with general requirements for electrical installations, including safety and equipment specifications, while Article 220 outlines load calculations for branch circuits and feeders. Article 240 covers overcurrent protection, which although important, pertains more to the safety mechanisms in place for protecting conductors and equipment rather than the specific regulations for feeder conductors themselves. Thus, Article 215 is the relevant section for understanding the standards and practices for feeders.
