How to Install a Dimmable Ballast
- 1). Install the dimmer switch first. The dimmer switch is commonly installed in the light switch box in the wall. Connect the black and white wires of the power input to the terminals on the input side of the dimmer. Connect the black and white wires of the cable leading to the dimmable ballast to the output side of the dimmer switch.
- 2). Fasten the black and white wires of the cable to the corresponding terminals of the dimmable ballast.
- 3). Fasten the dimmable ballast to the light fixture housing. This is commonly done with screws, furnished with the ballast, that fit through predrilled holes in the ballast and into holes in the light fixture.
- 4). Fasten the light fixture wires to the output side of the ballast. There are commonly three color-coded wires for each fluorescent tube in the light fixture. Fasten the wires to the appropriate color terminals in the dimmable ballast.
