Which NEC article provides the specific and general requirements for branch circuits?

• A. Article 210
• B. Article 250
• C. Article 300
• D. Article 400

Answer: (A)

The main idea here is understanding where branch-circuit rules live in the NEC. Branch circuits are the paths from a final overcurrent device that carry power to outlets, lighting, and other loads. The article that provides both the general requirements for any branch circuit and the specific provisions that apply to branch circuits is Article 210. It lays out how conductors are sized for branch circuits, the types of protection required, rules for receptacle outlets, and the AFCI/GFCI protections that apply in various locations. It also covers the way branch circuits are organized in dwelling units versus other occupancies, helping you know what’s required in practical installations. This is why it’s the best reference for branch-circuit requirements, as other articles address grounding (Article 250), general wiring methods and installation rules (Article 300), or flexible cords (Article 400) rather than branch circuits themselves.
