Electrical box cable management and support bracket assembly, system and method

An electrical box assembly to be mounted on a first wall, comprising:

• an electrical box having a top wall, a bottom wall opposing the top wall, and a back wall;
• and
• a support bracket positioned proximate the back wall of the electrical box and coupled to the electrical box, the support bracket comprising a plate member and a cable management member extending laterally from the plate member, the cable management member forming at least one pass-through opening sized to receive an electrical cable that is further received in the electrical box, the plate member comprising a bending line that divides the plate member into a first portion and a second portion, the bending line extending substantially parallel with a part of the cable management member that forms the pass-through opening, wherein the plate member has first and second configurations, the plate member is generally planar in the first configuration, and when the plate member is in the second configuration the first portion of the plate member bends along the bending line and extends laterally from the second portion to engage a second wall opposing the first wall and opposing the back wall of the electrical box, the first portion of the plate member and the cable management member extending away from opposite faces of the second portion of the plate member.
