How to Install a Dimmer Switch

Do you prefer a more customized approach to indoor lighting? Do some family members like bright lights, while others enjoy a low-key ambiance? Dimmer switches give home owners a chance to create a comfortable environment that suits a variety of personal tastes and occasions. Need to study or work on a detailed project? Turn your lights to the brightest setting. Preparing for a Friday night cocktail party? Instantly change to a shade that perfectly matches the evening’s mood. Are you interested in installing a dimmer switch? At Mr. Electric of Fort Worth, TX, we want your electrical projects to be safe and effective. Here are a few tips to help ensure your dimmer switch installation is a success. 

Make Sure Your Current Lights are Compatible with a Dimmer Switch

Do research ahead of time and find out if your current light bulbs can be dimmed. You may need to purchase a different set of bulbs that are compatible with dimmers. And, ceiling fan light fixtures may require specialized dimmers that are designed to prevent motor damage. Read the materials that came with your current bulbs, ceiling fans and light fixtures, and call the manufacturer if you have any questions or concerns. 

Gather Your Supplies

Once you’ve determined that you’re ready to install your dimmer switch, the first step is to collect all the tools, supplies and materials needed for the task. You’ll need the dimmer switch, a screwdriver, voltage detector, wire strippers and a flashlight.

Turn Off the Power

The most important step in this process is to turn your power off at the breaker box. Working with electrical wires can be very dangerous, and you must do everything possible to avoid electrocution or electrical fires. Double check that the light fixture is receiving absolutely no electrical current by using your voltage detector. 

Get Rid of the Old Switch

Use your screwdriver to remove the current plate cover and switch. Loosen and snip the ends of the existing wires using your wire strippers. You’ll need to remove ¾ inch of the casing in order to properly connect the new wires. 

Thoroughly Read the Instruction Manual for Your Specific Model

It’s important that you know which wires to connect. Your manufacturer’s directions should inform you. In most cases, the green wire will be the ground wire and the black wire will be connected to the dimmer. 

Installing Standard Single Pole Dimmer Switches

A standard or single pole dimmer switch is designed to be turned on or off from a single location. To install this type of switch, you’ll need to connect the green wire or copper wire in the box by twisting the ends together with a connector nut. Next, you’ll need to connect the black dimmer wire to the house wires. Again, tighten the ends together using wire nuts. 

Installing Three-Way Dimmer Switches

If your lights can be turned on or off from multiple locations, you’ll need to install a three-way dimmer switch. For this installation, you’ll need to remove the ¾ inch casing from your house wires. Connect the green wire to the existing green or copper wire inside the wall box, connect using the wire connector nut. Then, you’ll connect the black dimmer wire to your common wire. Finally, you’ll need to connect the additional two traveler wires. 

Put the Cover Plate in Place

Once the wires are all properly connected, place the wires neatly inside the box, and screw the new dimmer switch plate onto the wall. 

Replace Your Bulbs if Needed

If you needed to purchase compatible bulbs, now is the time to replace your existing lights.  

Restore Your Power and Test Your New Dimmer 

The final step is to turn on the power to your light fixture at the breaker box. Test your dimmer switch to ensure that it’s working properly. If the light isn’t working, the light won’t dim or you suspect that a wiring issue is present, you may want to get help from a certified electrician who can ensure the task is performed safely and effectively.
