Why Does Installing Electrical Boxes Flush with Drywall Matter? Therefore, if you plan to add additional material to your wall, the edges of your electrical box must protrude further out than the drywall thickness to account for the additional wall material. For instance, decorative tile, adhesive faux tile panels, and similar wall coverings will add additional thickness to the underlying drywall. One thing to consider as far as determining the proper depth of electrical boxes is whether additional material will be applied on top of the drywall. (Source: Better Homes & Gardens) Outlet box depth gauges used to ensure proper drywall fit. Many electrical boxes available today come with depth gauges built into them, so you can quickly determine the proper position of the box and fasten them in short order without going through the additional step of measuring depth with a piece of drywall. Once the correct positioning is verified, you can proceed with fastening the electrical box to the stud or joist permanently.Adjust the depth of the electrical box against the stud or joist so that the outer edges are flush with the piece of drywall when it is held against the side of the box.With the electrical box positioned, but not yet fastened to a stud or joist, hold a piece of scrap drywall of the same thickness as what will be installed, and lay it against the side of the electrical box.The standard thickness of drywall is either 3/8” or 1/2″ (1/4” and 5/8” drywalls are also available, but these are non-standard thicknesses).This phase of the work is done before the drywall is put up, so proper positioning is important so that when the drywall is installed, the edges of the electrical box end up being flush with the drywall surface.įortunately, there are a couple of simple tips and steps that take the guesswork out of installing electrical boxes at the proper wall depth: When installing electrical boxes, they are typically mounted to studs or joists for greater stability.

In the case of combustible materials like wood paneling, the edges of the electrical box must be completely flush with the wall or ceiling surface. (Source: This Old House)Īccording to Article 314.20 of the National Electrical Code, electrical boxes that are installed in walls or ceilings with surface materials consisting of “concrete, tile, gypsum, plaster, or other non-combustible material” must be positioned such that the forward (outer) edge of the box is recessed no more than one-quarter inch.
They can vary in size and shape but are most commonly configured for one (single-gang) or two (double-gang) electrical hookups.Īs such, electrical boxes serve a vital function as far as electrical and fire safety in a home or structure.
Should Electrical Boxes Be Installed Flush with Drywall?Įlectrical boxes are designed to safely contain the electrical wiring for things like electrical outlets and light switches.
