    BACKGROUND OF THE INVENTION



    [0002] Electrical installation boxes are used to terminate an electrical conduit in a structure frame. The installation boxes are attached to wooden or metal beams using a mounting bracket. The mounting bracket is then attached to an installation surface for example, concrete, bricks, plaster boards and wooden boards of varying thickness. Hence the mounting bracket must be compatible with different installation conditions.

    [0003] In conventional electrical installation systems, the mounting bracket is fixed to the beam by means of external nails or screws. Such prior art approach requires skilled persons to integrate the mounting bracket with the mounting box and the beam. Also, the mounting box may be accidentally removed from the mounting bracket by external forces or the mounting box may slip out from the mounting bracket when it pushed by cables in existing solutions which may damage the electrical parts on the mounting box. Furthermore, the adjustment of the mounting box with respect to the installation surface is performed only after removing the bracket from the mounting box. Hence, installation of the conventional mounting bracket assembly takes a substantially long time due to the required adjustment for the board/wall thickness and does not provide smooth operation.

    [0004] EP2903110 discloses a mounting bracket assembly for an electrical installation box comprising a mounting box having a circular projection and rails, an L-shape beam member and an L shaped bracket having a flange, whereby the beam member and the bracket slide on the rails and the flange is bent to lock the beam member with the mounting box.
