10 Most Common Electrical Mistakes DIYers Make

Recessing Boxes Behind the Wall Surface

Mistake: Exposed combustible material

This mistake refers to the improper installation of electrical boxes, particularly when they are recessed behind combustible materials like wood. When electrical boxes are not flush with the wall surface, combustible materials are left exposed to potential heat and sparks, creating a fire hazard.

Solution: Add a box extension

The suggested solution involves installing a box extension to ensure that the electrical box is flush with the wall surface. This can be achieved by using a metal or plastic box extension, depending on the type of box being used.

If a metal box extension is used on a plastic box, it is important to connect the metal extension to the ground wire in the box. This can be done using a grounding clip and a short piece of wire, ensuring proper grounding and electrical safety.

By adding a box extension, individuals can eliminate the exposure of combustible materials to potential heat and sparks, reducing the risk of fire hazards.
