said mounting frame includes a brace extending from said side walls into said enclosure of said mounting frame;

said brace positioning said mounting device at said back wall of said mounting frame and away from said end walls of said mounting frame;

said mounting device is selected from the group including a low voltage mounting plate and a high voltage box; and

said mounting device including a first frame with a first lip extending there from, a second frame with a second lip extending there from, and an arm extending from said second lip, said first lip of said mounting device is at an angle of 60 degrees with respect to said first frame, and said second lip is at an angle of 30 degrees with respect to said second frame.

2. The electrical device mounting assembly of claim 1 wherein said mounting arrangement includes a plurality of rotatable clamp arms extending through said mounting frame.

3. The electrical device mounting assembly of claim 1 wherein said mounting arrangement includes

a flange extending from each of said side walls of said mounting frame;

a plurality of inner apertures in each of said flanges of said mounting frame, said inner apertures in said mounting frame are oversize apertures;

a plurality of mounting fasteners extending through said oversize apertures in said flanges; and

a rotatable clamp arm attached to each of said mounting fasteners.

4. The electrical device mounting assembly of claim 1 wherein said attachment arrangement for securing said mounting device within said enclosure includes

tabs and a boss on said mounting frame;

said arm on said mounting device; and

a fastener for securing through said arm of said mounting device into said boss on said mounting frame.

5. The electrical device mounting assembly of claim 1 wherein said brace is at an angle with respect to said front face of said mounting frame thereby positioning said mounting device at said angle with respect to said front face of said mounting frame.

6. The electrical device mounting assembly of claim 1 including a trim plate wherein said trim plate includes

a frame having a front side and a rear side with an inner periphery and a central opening therein; and

a peripheral wall extending from said rear side of said frame around said inner periphery, said peripheral wall adapted for nesting within said side walls and end walls of said mounting frame.

7. The electrical device mounting assembly of claim 6 wherein

said flanges of said mounting frame include outer apertures therein;

said frame of said trim plate includes outer apertures therein; and

said trim plate is secured to said mounting frame by securing plate fasteners through said outer apertures of said trim plate into said outer fasteners of said mounting frame.

8. The electrical device mounting assembly of claim 7 wherein

said frame of said trim plate includes inner apertures therein;

said mounting fasteners of said mounting frame include heads;

said inner apertures in said trim plate are in axial alignment with said mounting fasteners when said trim plate is secured to said mounting frame; and

said inner apertures in said trim plate are of a larger diameter than said heads of said mounting fasteners enabling said mounting fasteners to rotate freely within said inner apertures of said trim plate when said trim plate is secured to said mounting frame.

9. The electrical device mounting assembly of claim 1 wherein said mounting device is a low voltage plate and said low voltage mounting plate includes

a frame opening within said first frame and said second frame; and

component connection points on said first and second frames.

10. The electrical device mounting assembly of claim 9 wherein said component connection points each include a component boss and a bore within said component boss.

11. The electrical device mounting assembly of claim 1 wherein

said first frame is at an angle with respect to said second frame; and

said angle is between 60 and 120 degrees.

12. The electrical device mounting assembly of claim 1 wherein said high voltage box includes a sidewall and an end wall extending from said first and second frames, said side wall and said end wall of said high voltage box defining an electrical enclosure therein.

13. The electrical device mounting assembly of claim 12 wherein said high voltage box includes a recessed area in said end wall and a knockout wall portion in said recessed area.

14. The electrical device mounting assembly of claim 1 wherein said mounting frame includes one or more slots in said end walls, said slots capable of receiving one or more fasteners therein for securing said mounting frame to a stud.

15. The electrical device mounting assembly of claim 1 including a second brace extending from said side walls of said mounting frame into said enclosure, said second brace at an angle with respect to said front face of said mounting frame; and

said second brace integral with one end of said brace.

16. The electrical device mounting assembly of claim 15 wherein

said brace of said mounting frame supports said first frame of said mounting device when said mounting device is secured within said mounting frame; and

said second brace of said mounting frame supports said second frame of said mounting device when said mounting device is secured within said mounting frame.
