Abstract

An electrical box assembly includes an electrical box, a movable partition plate, and a cover having an opening for receiving and supporting an electrical wiring device such as a switch or duplex receptacle. The electrical box has a rear wall with a centrally located emboss having a plurality of screw holes for receiving a ground screw and ground wire. The partition plate has a recess for mating with the emboss and a top end for coupling with the cover member. The partition plate and cover member are adapted for coupling to the electrical box in different orientations so that the partition plate divides the electrical box into substantially equal size compartments for receiving high voltage and low voltage requirements.

a partition plate having a bottom edge coupled to said rear wall and a top edge received in said slots in said cover member, said partition plate being selectively coupled to said rear wall in a first position and a second position perpendicular to said first position, said partition plate dividing said electrical box into two substantially equal size compartments in said first and second positions; and

said electrical box having a centrally located raised emboss in said rear wall, said emboss being located to be partially positioned in each said compartments.

9. The assembly of claim 8, wherein

said emboss has at least one screw hole positioned on a first center line extending through said emboss and electrical box, and at least one aperture spaced outwardly from said emboss and positioned on said center line;

said partition plate having a centrally located recess in a bottom edge for receiving said emboss.

10. The assembly of claim 9, wherein

said bottom edge of said partition plate has a projecting detent received in said at least one aperture in said rear wall.

11. The assembly of claim 8, wherein

said partition plate having a top edge with a first corner received in said first slot and a second corner received in said second slot.

12. The assembly of claim 11, wherein

said first corner having a notch therein for mating with said first slot;

and

said second corner having a notch therein for mating with said second slot.

13. The assembly of claim 9, wherein

said partition plate having a coupling tab on a bottom edge for coupling to said emboss.

14. The assembly of claim 13, further comprising

a ground screw adapted for extending through said coupling tab in said partition plate and received in said at least one screw hole in said emboss and where said partition plate is aligned with a second center line perpendicular to said first center line.

15. The assembly of claim 14, wherein

said emboss has at least one second screw hole aligned with said second center line, and where said ground screw is adapted for extending through said coupling tab in said partition plate and received in said second screw hole to align said partition plate along said first center line.

16. An electrical box assembly, comprising:

an electrical box having a rear wall, a side wall extending from said rear wall and an open top end opposite said rear wall, said electrical box having a substantially equal length and width, said rear wall having a central emboss extending into said electrical box and having a first screw hole and a second screw hole;

a cover member adapted to be coupled to said open top end of said electrical box in a first position and in a second position perpendicular to said first position, said cover member having an inner edge defining a central opening with a dimension to receive an electrical wiring device, said inner edge having a plurality of apertures for receiving mounting screws of the wiring device, a first recess on a first side of said inner edge and a second recess on a second side of said inner edge; and
