ABSTRACT:
A wire guard for filling an opening in an electrical box, to protect contents contained therein, includes a plate having a circumferential wall projecting outward from the plate at a defined angle. The wall extends for a length of a perimeter of the plate, contacting an interior surface of the electrical box when the plate fills the opening. At least one bracket of the wire guard surrounds a tab formed in the electrical box. Further, an aperture in the bracket aligns with a bore hole in the tab. A mechanical fastener, e.g. a screw, may be inserted into the aperture to engage with the bore hole of the tab, thereby fastening the wire guard to the electrical box. A screw driver or other tool, inserted into an aperture in the plate, may be used to extract the wire guard from the electrical box after use.
