Plastic conduit is commonly regarded as an exposed installation method. This method involves installing the plastic conduit directly on the surface of the building, offering a clean, aesthetically pleasing appearance, and ease of maintenance and upgrades. Specific applications of exposed plastic conduit installation include along walls or ceilings, where it can be secured using plastic conduit clips, steel staples, ceramic plates, or plastic conduit boards.

Direct burial and concealed wiring are two different methods of cable installation:

Exposing wire channels on the building's surface facilitates maintenance and updates, but may affect the appearance.

Subterranean Installation: Buries the wire channel within the building structure, maintaining an unobtrusive appearance, but with greater difficulty in construction and maintenance.

The choice between exposed and concealed wiring depends on the specific building requirements and usage environment. Exposed wiring is suitable for situations that require easy maintenance and updates, while concealed wiring is ideal for environments with higher aesthetic requirements.
