An electrical box assembly for concrete pours that includes an improved leveling ring and can be adapted to mount either high or low voltage components or a combination of high and low voltage components. The leveling ring for leveling an electrical component with respect to the concrete surface includes one or more legs extending outward of the ring's periphery for improving adhesion of the ring with the inner surface of the electrical box. The versatility of the electrical box is improved by a slide member that can be inserted within the enclosure of the electrical box in order to subdivide the enclosure into high and low voltage compartments. Leveling rings are provided in two embodiments for mounting conventional electrical box covers, one for mounting a flat electrical box cover and one for mounting a pop-up electrical box cover.

1. An electrical box assembly for installing an electrical component within a surface, said electrical box assembly comprising: an electrical box including a bottom wall and a peripheral wall defining an electrical enclosure with an inner wall therein, said peripheral wall including a top and a bottom;a channel extending along said bottom wall of said electrical box into said electrical enclosure;a leveling ring for leveling the electrical component with respect to the surface, said leveling ring including an upper surface, a lower surface, a vertically arcuate outer surface of the ring to fit snugly within said electrical enclosure, and a leg extending downward from said lower surface, said leg enabling the ring to bond more securely to the electrical box;said electrical box including a plurality of feet for anchoring said electrical box to a surface and one or more hubs for receiving electrical conduit therein, said hubs extending from said bottom of said peripheral wall;a slide member for dividing said electrical enclosure vertically into a high voltage compartment and a low voltage compartment, said slide member having a bottom edge, said slide member adapted to slide within said electrical enclosure and engage said channel; andtwo parallel rails extending from said bottom wall into said electrical enclosure and forming said channel. 2. The electrical box assembly of claim 1, wherein said leveling ring includes an outer periphery and an inner periphery; andone or more cover attachment arms extending inward from said inner periphery. 3. The electrical box assembly of claim 2, wherein each of said cover attachment arms include a bore therein; anda brass insert pressed within each of said bores in said cover attachment arms. 4. The electrical box assembly of claim 3, wherein at least one of said brass inserts in each of said cover attachment arms includes a ground wire secured thereto. 5. The electrical box assembly of claim 2, including a collar extending from said inner periphery of said leveling ring; andsaid collar extending around the entirety of said inner periphery. 6. The electrical box assembly of claim 2, wherein said leveling ring includes one or more component attachment arms extending inward from said inner periphery;each of said component attachment arms including a bore therein; anda brass insert pressed within each of said bores in said component attachment arms. 7. The electrical box assembly of claim 2, wherein each of said cover attachment arms includes a slot therein; anda metal clip member pressed within each of said slots in said cover attachment arms. 8. The electrical box assembly of claim 7 wherein said metal clip member includes a planar base with an opening therein; anda lip extending orthogonally from said planar base. 9. The electrical box assembly of claim 8 wherein said opening in said planar base of said clip member includes a flat edge; andeach of said cover attachment arms include a tab in axial alignment with one of said slots, whereby pressing of said clip member into said slot enables said tab to engage said opening in said clip member thereby locking said clip member to said leveling ring. 10. The electrical box assembly of claim 1, including a pour cap adapted for sliding over and covering said top of said peripheral wall. 11. The electrical box assembly of claim 10, wherein said pour cap includes a top; anda sidewall of said pourcap, said sidewall of said pourcap including a lower edge. 12. The electrical box assembly of claim 1, wherein said leg of said leveling ring includes an arcuate outer surface; andsaid arcuate outer surface of said leg is coextensive with said arcuate outer surface of said leveling ring. 13. The electrical box assembly of claim 1 wherein said slide member includes a body;a shoulder on said body;notches on opposing sides of said body; anda top edge. 14. The electrical box assembly of claim 1 including a pop-up electrical cover with a lock portion and a hinge portion, wherein said upper surface of said leveling ring includes a notch therein for accommodating said lock portion of said pop-up electrical cover; andsaid upper surface of said leveling ring includes two notches therein for accommodating said hinge portion of a pop-up electrical cover. 15. The electrical box assembly of claim 1, wherein said leg extends at least 0.5 inch from said lower surface of said leveling ring. 16. The electrical box assembly of claim 1, wherein said leveling ring includes three of said legs; andsaid legs are arranged 120 degrees apart on said leveling ring. 17. The electrical box assembly of claim 1, including a leveling ring adapter, said leveling ring adapter including a ring portion including an outer periphery, an inner periphery, and an upper surface;a lip extending inward from said inner periphery of said ring portion; anda notch in said lip of said ring portion for accommodating passage of said leg of said leveling ring. 18. The electrical box assembly of claim 17, wherein said leveling ring adapter includes a plurality of narrow tabs extending upward from said upper surface of said ring portion;a plurality of wide tabs extending upward from a juncture with said upper surface of said ring portion; anda notch on said ring portion at said juncture of said wide tabs with said ring portion, said notch enabling removal of said wide tabs in order to reduce the outer diameter of said leveling ring adapter. 19. The electrical box assembly of claim 1, including a reducer for closing off one or more of said hubs, said reducer including a substantially tubular reducer body including an open end with a flange thereon; anda nose portion extending from said flange to a closed end. 20. The electrical box assembly of claim 1, including a Y-connector for adapting said hub to accept two electrical conduits, said Y-connector including a substantially tubular body including an inlet end with two inlet openings and an outlet end with one outlet opening defining a substantially Y-shaped inner passageway therein;said inlet end of said Y-connector including two conduit seats therein; andsaid outlet end of said Y-connector including a nose portion adapted to fit snugly within one of said hubs.
