Which NEC section contains required branch circuits?

• A. NEC Article 408
• B. NEC Section 230.71(B)
• C. NEC Section 600.5(A)
• D. NEC Section 220.46

Answer: (C)

The key idea is where NEC defines the requirement to have dedicated or multiple branch circuits for certain equipment. In the NEC, the rule about required branch circuits is found in a section under Special Equipment, which specifically calls out that certain loads must have a prescribed number of branch circuits available to serve them. That makes it the best answer because it directly addresses the concept of “required branch circuits.” Other sections focus on different topics: one deals with how panelboards and distribution equipment are arranged and installed, another covers service disconnects in dwelling or other setups, and another covers how to calculate lighting loads. They don’t establish the requirement for dedicated branch circuits, so they aren’t the correct reference for this question. So, the section that explicitly uses and governs the concept of required branch circuits is the one in Special Equipment, Section 600.5(A).
