Abstract: A retrofit multi-gang electrical box for receiving plurality of electrical devices and wirings is disclosed. The electrical box comprising an electrical enclosure defining a side walls, a lower wall, an upper wall and a rear wall, the rear wall having a perimeter adjoining the side walls, the lower wall and the upper wall forming a L-shaped cavity. A plurality of channels disposed at the rear box wall for receiving electrical wires. A complementary cover assembly configured to removably affix to an opening of the cavity of the electrical enclosure. A plurality of top engaging formation and bottom engaging formations arranged in a facing mirror image relationship relative to one another for receiving an electrical outlet member.

Abstract: A power and control assembly is disclosed. An LED driver is sized and adapted to fit within a single compartment of an electrical gang box, such as a two-gang box. An alternating current (AC) dimmer or other component is installed in an adjacent compartment. The AC dimmer supplies its output to the LED driver, which converts the AC power to an appropriate direct current (DC) power for LED lighting fixtures. The LED driver is typically recessed into the compartment, and is covered by a switch or another control element. In some cases, the switch may be a mechanical dummy selected for its aesthetic or fascial characteristics. In other cases, the switch or control element may be functional. With similar multiple-gang boxes, a number of drivers may be installed in the gang box and switches may allow both dimming and zone control.
