Which NEC reference mentions switchboards, switchgear and panelboards?

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

Answer: (A)

The key idea here is that switchboards, switchgear, and panelboards are specifically covered by a single NEC article that sets forth their requirements. NEC Article 408 is titled “Switchboards, Switchgear, and Panelboard Assemblies,” and it lays out the rules for the construction, installation, listing, labeling, and safe operation of this distribution equipment. Because the question asks which reference mentions these three types of equipment, Article 408 is the one that directly addresses them, making it the best and most accurate choice. The other references reference different parts of the code. They deal with topics that do not focus on switchboards, switchgear, and panelboards, so they aren’t the correct match for this question.
