Abstract

An electrical box assembly includes an electrical box having a removable partition plate that can be positioned between the ends of the electrical box or at the end of the electrical box when two or more of the electrical boxes are ganged together. The electrical box can include a mounting bracket having a body portion attached to a wall of the box for supporting the box during use. A support member is coupled to the mounting bracket and is extendable to a length to contact the opposing wall. The mounting and the support member are independently adjustable with respect to the box.

said first mounting bracket being adjustable with respect to the open top end of said electrical box to adjust the position of the electrical box with respect to the support structure.

2. The electrical box assembly of claim 1, wherein

said electrical box has a partition plate having a bottom edge with a tab for coupling said partition plate to said rear wall, and opposite side edges having removable tabs to form a recess with a dimension to receive a coupling screw extending inwardly from said electrical box.

3. The electrical box assembly of claim 1, wherein

said first mounting bracket includes a longitudinally extending slot configured for mating with a coupling screw for adjusting the position of the mounting bracket with respect to said electrical box.

4. The electrical box assembly of claim 3, wherein

said first wall has an outwardly extending detent;

and

said first mounting bracket includes a plurality of spaced-apart apertures for mating with said detent to position said first mounting bracket in a selected position with respect to said first wall and to position said flange of said first mounting bracket a selected distance from the open top end of the electrical box.

5. The electrical box assembly of claim 1, further comprising

a support member coupled to said first mounting bracket, said support member being adjustable with respect to said first mounting bracket and configured for contacting the opposing wall to support said electrical box.

6. The electrical box assembly of claim 5, wherein

said support member has a distal end with an inwardly extending flange configured for contacting a wall surface to support said electrical box.

7. The electrical box assembly of claim 6, wherein

said first mounting bracket includes a body portion coupled to said first wall, a flange extending outward from a bottom end of said body portion, and a longitudinally extending leg extending from said flange and being spaced from a plane of said body portion and spaced from said first wall.

8. The electrical box assembly of claim 7, wherein

said leg includes a detent to contact said first wall and space said leg from said first wall of said electrical box.

9. The electrical box assembly of claim 8, wherein

said leg of said first mounting bracket has a screw received in a threaded hole in said leg;

said leg of said support member includes a longitudinal slot configured for receiving said screw and extending through said leg for adjusting the position of said support member with respect to said leg of said first mounting bracket, and where said leg of said mounting bracket is spaced from said first wall a distance to prevent interference of said screw with said first wall.

10. The electrical box assembly of claim 1, further comprising;

a second mounting bracket having a body portion with an elongated slot receiving a screw threaded into said second side wall for adjustably coupling said second mounting bracket to said second side wall and positioning said second mounting bracket a selected distance from said open top of said electrical box;

said second mounting bracket having a top end with an outwardly extending flange with a dimension for contacting an inner face of a wall panel, and a bottom end with a flange spaced from said electrical box for contacting the surface of the opposing wall and spaced a first distance from said electrical box, and

a support member having a longitudinal slot receiving a screw received in a threaded hole in said second mounting bracket for sliding said support member on said second mounting bracket, said support member having a plurality of apertures oriented in a longitudinal direction of said support member for mating with a detent on said second mounting bracket to position an end of said support member a selected distance from said electrical box.

11. An electrical box assembly comprising:

an electrical box having a rear wall, a first wall and a second opposing wall, and an open end, said first and second opposing walls having a flange configured for supporting an electrical device in the open end of said electrical box;

a first mounting bracket having a body portion coupled to said electrical box and being adjustable relative to the open top of said electrical box, said mounting bracket having a flange extending outward from a top end of said body portion and configured for coupling to a support structure to support said electrical box and position said electrical with respect to a first wall, said first mounting bracket having a flange extending from a bottom end, and said first mounting bracket having a length to contact a second opposing wall spaced a first distance from said first wall; and

a support member coupled to said mounting bracket and being slidably adjustable with respect to said first mounting bracket to contact a third wall spaced a second distance from said first wall.

12. The electrical box assembly of claim 11, wherein

said first mounting bracket has a leg extending substantially parallel to said body portion and spaced outwardly from a plane of said body portion by a flange, and

said body portion of said first mounting bracket is coupled to said first wall and said leg is spaced outwardly from said first wall.

13. The electrical box assembly of claim 12, wherein

said support member is coupled to said leg by a fastener and where said leg is spaced from said first wall a distance to prevent interference of said fastener with said first wall.

14. The electrical box assembly of claim 13, wherein

one of said support members or said leg further comprises at least one detent, and the other of said support member and leg has at least one aperture for receiving said detent to position said support member in a selected position with respect to said leg;

and

said support member includes a longitudinally extending slot receiving a coupling screw received in a threaded aperture in said leg for adjusting the position of said support member with respect to said first mounting bracket.

15. The electrical box assembly of claim 12, wherein

said leg of said first mounting bracket includes a detent contacting said first wall to space said leg outwardly from said first wall.

16. An electrical box assembly comprising:

an electrical box including a rear wall, a first wall and an opposing second wall, and an open top end;

a first mounting bracket having a body portion coupled to said first wall, a second mounting bracket having a body portion coupled to said second wall, each said mounting brackets having a flange extending outwardly from a top end of said body portion and a leg extending from said body portion with a length for contacting an opposing wall surface, said flange of said first mounting bracket configured for coupling to an outer face of a support structure for supporting a first wall, said flange of said second mounting bracket configured for contacting an inner surface of and supporting the first wall, each mounting bracket being independently adjustable with respect to said respective first wall and second wall; and
