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

The term for a separate portion of a conduit or tubing system that provides access through a removable cover is a conduit body. This component is specifically designed to allow for easy access to the electrical conductors within a conduit system for maintenance, splicing, or pulling wires through. Conduit bodies often have removable covers to facilitate this access.

Conduit bodies are essential in complex wiring systems, where changes in direction or branching may be required. They come in various shapes and sizes to accommodate different configurations and provide solutions to routing issues while maintaining the integrity of the conduit system.

Other options, while related to electrical installations, serve different purposes. A conduit connector is used to join two sections of conduit together, and a pull box is used to facilitate the pulling of wires through long runs of conduit but is not a body with removable access. Raceway refers more generally to any system that encloses electrical wiring, which does not specify the access feature.
