Installing a Dimmer Switch Instructions

  • Installing a Dimmer Switch

    You can quickly change the mood of a room by dimming the lights which creates a comfortable, more relaxing atmosphere. Dimmer switches come in four popular styles: dial, slide, touch pad, and a combination light switch/dimmer slide. You should always follow the installation instructions included with the switch, however most dimmer switches have similar installation requirements that will be discussed in this tutorial.

  • Overview

    Replacing a light switch with a dimmer switch is a relatively easy job. First, shut off the power at the fuse box. Second, remove the old switch. Third, install the new dimmer switch. Finally, turn the power back on and check to make sure it’s working properly.

  • Turn Off Power

    Turn off the circuit that you will be working on. Find the right breaker in the breaker box and flip it to the "Off" position. If you have a fuse box, find the right fuse and remove it completely from the panel. Double check that the circuit is off by turning the light switch on.

  • Remove Old Switch

    Use a screwdriver to remove the old switch plate. Next, remove the old switch from the workbox by unscrewing the screws on the top and bottom of the switch. Remove the wires connected to the old switch.

  • Prepare Wires

    Using a wire cutter, cut off the bare wire just below the plastic insulation on all wires. Then use a wire stripper to strip off about 3/8” of the insulation. This will give you a clean piece of wire for the new connection to the dimmer. If needed, strip the wires that are already attached to the dimmer switch.

  • Connect the Wires

    Connect one of the black wires in the workbox to one black wire from the dimmer switch by placing the bare wires next to each other. Then twist on a wire nut in a clockwise direction. Make sure that the bare wires are completely encased in the wire nut. Do the same for the other set of black wires. The white or neutral wires should be twisted together and capped with a wire nut. Be sure to tie together the green ground wires as well.

  • Fasten the Dimmer

    Bend the wires in a zigzag pattern so that they easily fold into the workbox. Push the switch into place. Adjust the switch so that it is perpendicular to the floor. Tighten the two screws that hold it in position in the workbox. Next, install the new dimmer switch plate.

  • Turn on the Power

    Switch the breaker back on (or re-install the fuse). Test the dimmer to make sure your installation was successful. If the dimmer doesn’t work, turn off the breaker and double check your wiring connections.
