Safety First!
- Be sure you have a dimmer switch that works with the type of light bulb you are using. CFL and LED light bulbs require special dimmer switches.
- The light fixture wattage must not exceed the dimmer capacity.
- Replace single pole switch with single pole dimmer and 3-way switch with 3-way dimmer.
- Install only one dimmer in a 3-way circuit.
- Wiring for your dimmer may not match the drawings below always verify with the manufacturer’s instructions.
NOTE: You will need to attach the dimmer leads using wire “nuts” or connectors. The wires from a dimmer switch will appear different than the wires attached to your existing switch. They are what are known as “stranded” wire. Stranded wire is composed of a bundle of small – gauge wires wrapped in a single piece of insulation to make a larger conductor. Stranded wire is more flexible than standard wire.
