What type of box is typically used for raceway entries?

Junction boxes are specifically designed to accommodate raceway entries, as they allow for the connection and distribution of conductors while providing a means to join different sections of raceways. These boxes help protect electrical connections and provide access for maintenance or modifications. They also enable the transition of wires from one wiring method to another, aligning with the requirements set forth in the National Electrical Code.

Outlet boxes, switch boxes, and flush-mount boxes serve different purposes. Outlet boxes are primarily intended for housing outlets where devices like receptacles are mounted. Switch boxes are designed to hold switches, and flush-mount boxes are installed level with a surface for aesthetic purposes or when devices are to be mounted flush with the wall. None of these types are specifically catered to the entry and transition of raceways in the way that junction boxes are, which makes junction boxes the most appropriate choice for that specific application.
