Which article would you refer to for guidelines on feeders?

The correct answer, which focuses on Article 215, pertains specifically to feeders in the National Electrical Code (NEC). This article outlines the requirements and regulations for feeders, which are essential in electrical systems for distributing power from the service equipment to the branch circuits. Article 215 addresses important factors such as load calculations, conductor sizing, and the installation requirements for feeder systems.

While other articles in the NEC cover various aspects of electrical installations, they do not specifically address feeders. Article 225 deals with outside feeders and branch circuits for buildings and structures, Article 230 covers services, and Article 110 focuses on general requirements for electrical installations. Understanding the specifics of Article 215 allows professionals to ensure that feeder systems are installed safely and effectively, maintaining compliance with the NEC standards.
