Article ____ contains much detail about outlet boxes, device (switch) boxes, pull boxes, junction boxes, and conduit bodies.

• A. 314
• B. 300
• C. 210
• D. 400

Answer: (A)

The concept here is knowing which NEC article covers boxes and fittings used in electrical enclosures. Outlet boxes, device boxes (switch boxes), pull boxes, junction boxes, and conduit bodies are all types of enclosures and fittings, so the relevant article is the one titled Outlet, Device, Pull, and Junction Boxes, Conduits, Fittings, and Accessories. This article lays out the requirements for these enclosures, including how they’re constructed, how to calculate box fill, and how to install and terminate conductors and devices inside them. Other articles focus on different topics—general wiring methods, branch circuits, or flexible cords—so they don’t address these specific boxes and fittings.
