A low-voltage divider assembly separates cables carrying different voltages within the riser to reduce interference between the cables and any one of a variety of sub-plates having different configurations for accommodating a variety of multi-service or single service electrical functionality can be incorporated with the box. ## Claims ### Claim 1 A electrical floor box assembly comprising: a rectangular metallic box having a bottom portion, a plurality of sides and a top portion; a cylindrical non-metallic riser disposed at least in part above the top portion of said rectangular metallic box; and a flat flange disposed on the top portion of said rectangular metallic box, with an opening through which said cylindrical non-metallic riser extends. ### Claim 2 (depends on 1) The electrical floor box assembly claimed in claim 1, wherein said cylindrical non-metallic riser includes an upper portion disposed outside of said rectangular metallic box and a lower portion disposed within said rectangular metallic box. ### Claim 3 (depends on 2) The electrical floor box assembly claimed in claim 2, wherein the lower portion of the cylindrical non-metallic riser includes at least one opening for receiving at least one electrical cable carrying power or data for either dual-service or single service application. ### Claim 4 (depends on 3) The electrical floor box assembly claimed in claim 3, wherein at least one side of said rectangular metallic box includes at least one threaded hole operable to receive the electrical cable or cables. ### Claim 5 (depends on 3) The electrical floor box assembly claimed in claim 3, further comprising a low-voltage divider or partition assembly operable to separate power cables from data cables. ### Claim 6 (depends on 3) The electrical floor box assembly claimed in claim 3, wherein said low-voltage divider comprises; a substantially flat platform having a dimension substantially the same as an inner dimension of the riser; at least one ramp disposed below said platform; and a tube disposed above said platform. ### Claim 7 (depends on 6) The electrical floor box assembly claimed in claim 6, wherein a lowermost portion of the at least one ramp contacts the bottom portion of said box, and an uppermost portion of the at least one ramp contacts the platform of said divider. ### Claim 8 (depends on 6) The electrical floor box assembly claimed in claim 6, wherein the power cables run through said tube and the data cables are disposed outside of said tube. ### Claim 9 (depends on 1) The electrical floor box assembly claimed in claim 1, wherein said metallic box is cast iron and the bottom portion, the sides and the top portion are integral. ### Claim 10 (depends on 1) The electrical floor box assembly claimed in claim 1, wherein said metallic box is made of stamped steel. ### Claim 11 (depends on 2) The electrical floor box assembly claimed in claim 2, wherein the upper and lower portions of the riser include a plurality of channels disposed vertically on the inside surface of the riser. ### Claim 12 (depends on 11) The electrical floor box assembly claimed in claim 11, further comprising: a planar divider or partition inserted within two of the channels, said planar divider contacting the bottom portion of the metallic box at one end thereof and another end thereof being substantially planar with a top edge of the upper portion of the riser to separate the riser into two sections. ### Claim 13 (depends on 2) The electrical floor box assembly claimed in claim 2, wherein the lower portion of the riser includes a vertical planar divider extending outward from the outside surface of the riser and at least one of the sides of said metallic box includes a vertical planar protrusion extending inward from the inside surface of the at least one side and the vertical planar protrusions of the metallic box and the vertical planar divider of the riser align with each other to separate the interior of the metallic box into at least two sections in the area outside of the riser. ### Claim 14 (depends on 10) The electrical floor box assembly claimed in claim 10, wherein the metallic box is coated with a fusion-bonded epoxy corrosion resistant finish. ### Claim 15 (depends on 4) The electrical floor box assembly claimed in claim 4, wherein at least on of said holes has a diameter greater than one-inch and accommodates a corresponding hub for maintaining a sufficient bend radius suitable for communication cabling fiber and other low voltage cables. ### Claim 16 (depends on 1) The electrical floor box assembly claimed in claim 1, further comprising markings disposed on the inside of said riser, said markings being indicative of the volumetric capacity within the floor box assembly. ### Claim 17 A electrical floor box assembly comprising: a metallic box having a bottom portion, a top portion and a plurality of sides, wherein at least one hole is provided through at least one of the sides; a cylindrical non-metallic riser providing access through said top portion of said metallic box; and a flat flange adjacent to the top portion of said metallic box and having an opening through which said cylindrical non-metallic riser protrudes, wherein an outer dimension of said flat flange portion is substantially the same shape and dimension as the top portion of said metallic box. ### Claim 18 (depends on 17) The electrical floor box assembly claimed in claim 17, further comprising protrusions disposed perpendicular and adjacent to an outer surface of said cylindrical non-metallic riser, wherein said protrusions are asymmetrically located on the surface of said cylindrical non-metallic riser. ### Claim 19 (depends on 17) The electrical floor box assembly claimed in claim 17, further comprising permanent markings on the integral flange corresponding to each of the at least one hole, wherein the markings indicate whether power or data are intended to be received through the respective hole. ### Claim 20 (depends on 17) The electrical floor box assembly claimed in claim 17, wherein said cylindrical non-metallic riser is electrically isolated from said metallic box. ### Claim 21 (depends on 17) The electrical floor box assembly claimed in claim 17, wherein said cylindrical non-metallic riser is removably attached to said metallic box. ### Claim 22 (depends on 17) The electrical floor box assembly claimed in claim 17, wherein said metallic box is made of either stamped steel or cast iron.
