Which NEC Article defines branch circuits related to service equipment?

The National Electrical Code (NEC) Article that defines branch circuits related to service equipment is Article 210. This article specifically addresses the requirements for branch circuits, which are crucial components of electrical installations that distribute electricity from the service equipment to various parts of a building or structure.

Branch circuits are essential because they carry the load from the distribution panel to outlets, lighting, and other devices. Article 210 covers important topics such as load considerations, conductor sizing, overcurrent protection, and requirements for different types of branch circuits (e.g., general-purpose, individual circuits for specific appliances).

Understanding that Article 210 focuses on branch circuits helps distinguish it from other NEC articles. For instance, Article 250 pertains to grounding and bonding requirements, Article 300 addresses general wiring methods and conductors, and Article 400 discusses flexible cords and cables. These articles, while important in their own right, do not specifically define the parameters and requirements for branch circuits connected to service equipment as Article 210 does.
