After the electrical rough-in

All cabling must be satisfactorily clipped to the frame and be adequately protected from mechanical damage. The protection is simply done by installing with the frame, and then covering with internal lining such as plasterboard. Where wires are on the outside of a wall, which is common in garages with brick walls, the cables must be run in a protective conduit.

Prior to installing internal wall linings ensure all electrical cabling is installed. To ensure their easy location once internal lining is complete the location of power points, lights and switches should be clearly marked on the floor of the building.

Non-permanent marking should be used where the existing floor is the final finished surface.
