Abstract
A support bracket and extra-low voltage control device for installation with an electrical outlet box provides the capability of attaching or removing extra-low voltage (normally 30 volts or less) control of AC power (normally supplied at 120 volts) circuits such as lights. A controlling device in an enclosure (also called a control module) is attached to the exterior of one wall of an electrical outlet box, so that AC 120 volt wiring from the control module AC controlling device (a relay, a triac or a transistor) enters the electrical outlet box through an aperture in the wall of the electrical outlet box. Extra-low voltage control wiring enters the control module through an aperture in the control module enclosure and connects either to a relay coil or to an opto-coupling device within the control module enclosure to provide physical separation between the two wiring systems. Optionally, the control module used may receive a radio frequency signal or a power line carrier signal and in these cases opto-coupling and extra-low voltage wiring are not required. The support bracket is attached to a joist or a wall stud so that the electrical outlet box, when attached to the support bra…
