Which NEC reference would you use for switchboards, switchgear and panelboards?

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

Answer: (D)

The topic being tested is which NEC article specifically governs distribution equipment like switchboards, switchgear, and panelboards. These devices are addressed in Article 408, which is dedicated to Switchboards, Switchgear, and Panelboards. Article 408 outlines the requirements for their construction, mounting, overcurrent protection, and installation as part of how power is distributed within a building. The other references pertain to different areas of the NEC—service disconnect locations, other specialized equipment, or dwelling-unit load calculations—so they do not cover these distribution devices. Therefore, Article 408 is the appropriate NEC reference for switchboards, switchgear, and panelboards.
