An electrical fixture mounting assembly is provided for quickly and easily mounting an electrical fixture to a bracket and brace assembly. The electrical fixture mounting assembly includes an electrical box, a brace assembly for attaching to a support structure and a bracket for attaching the electrical box to the brace. The brace assembly is typically and adjustable member that extends between ceiling joists located above an aperture in a ceiling. The bracket is connected to the brace by a snap fit. The bracket includes retention fingers that are resilient to snap onto the brace and prevent movement of the bracket with respect to the brace during installation of the electrical box. The bracket includes tabs with threaded apertures for receiving mounting screws. The electrical box includes circular apertures and at least one keyhole shaped slot aligned with the threaded apertures in the flanges of the bracket. At least one threaded screw is attached to the flange of the bracket which is then inserted through the keyhole shaped slot. The electrical box is then rotated slightly with respect to the bracket to temporarily secure the electrical box to the bracket and align all of the apertures in the electrical box with the threaded apertures and the bracket. The screws are then inserted through the bottom of the electrical box and tightened to secure the electrical box to the bracket. The flanges on the bracket are oriented and include cut-out portions to enable access to knockouts in the bottom wall of the electrical box.
