What is the term for a separate portion of a conduit or tubing system that provides access through a removable cover?

The correct term for a separate portion of a conduit or tubing system that provides access through a removable cover is known as a conduit body. Conduit bodies serve a critical function in electrical installations by allowing for the connection of multiple conduit runs, providing accessibility for wire pulling, and facilitating changes in direction within the conduit system. They are designed with openings that allow for access to the wiring inside, making it easier to inspect and maintain the electrical connections.

Understanding conduit bodies is important because they enhance the efficiency and safety of conduit systems by allowing for repairs or modifications without the need to dismantle large sections of the conduit. This feature also ensures compliance with electrical codes, which often require access to wiring for maintenance.

Other terms, such as conduit connector, pull box, and raceway, refer to different components or functions within conduit systems. A conduit connector typically serves to join two sections of conduit, while a pull box is specifically designed to hold wires and facilitate the pulling process over long distances, and a raceway encompasses a broader category of wiring methods that may or may not have removable covers.
