Can I replace a regular switch with a dimmer switch?
A dimmer switch can be an excellent replacement for a regular light switch. It helps conserve energy and makes your home look cozy, which is precisely why many people want to use them.
There is no doubt that lighting has a big impact on our home’s ambiance and feel. Besides making a home look more comfortable and pleasant, efficient lighting also conserves energy. And as a result, this helps save more money too.
However, electricity can be an expensive necessity if it is not installed and used correctly.
What dimmer lighting does is reduce the light bulbs’ brightness and allow the lights to function in a milder, less bright fashion. However, for many people around the world, hiring an electrician can be difficult or expensive. Although an electrician will not charge much for replacing a light switch with a dimmer switch, many people might still prefer to do it themselves.
If you are someone who’s looking to do this, you’re in luck! Fortunately, this is a relatively simple process.
10 Steps in Installing a Dimmer Light Switch
Before starting the process, please prepare the following tools:
- A voltage tester
- A wire stripper
- Tape measure
- 4-in-1 screwdriver
- Needle-nose pliers
After preparing the things you need, follow these steps in order to replace your light switches successfully. You should see an in-depth guide on how each step each done as you read on.
- Turn Off the Power
- Check for Hot Wires
- Remove the screws of the switch
- Check Box Volume
- Pay Attention to the Gauge of Wire
- Test the Ground
- Turn the Power Off
- Add your new dimmer
- Connecting the Wires
- Put the Cover Plate back on
It is essential to understand this guide and follow it closely. When working with electrical components, your top priority should be your safety. At any point you feel unsure of the process and doubt your ability to execute the conversion, you should stop and call a licensed electrician to have a look at your lights and do the replacement for you.
Step 1: Turn Off the Power
When dealing with wires and electricity, the first step should always be to ensure your safety. It might seem very obvious, but it can lead to a hazardous situation if one forgets this crucial step.
Therefore, it is necessary to make sure the power is off. I recommend that you double-check by turning the light on at the switch, so there is no room left for any accident.
Step 2: Check for Hot Wires
The second step would be checking for hot wires. For this, remove the plate of the switch by unscrewing it. Now, with the help of a non-contact voltage tester, check for hot wires.
This type of voyage tester will help ensure that there are no wires carrying voltage. This is also one way to determine whether the power is off. By holding the tip of the voltage tester around each screw terminal, simply check for hot wires.
Step 3: Remove the screws of the switch
Do so by loosening the screws on the plate and then remove them from the box. To keep a record, I recommend taking a picture of the wiring with your cell phone.
You will find a red/brown wire for life in the box and a black/blue one for neutral. There will be another wire colored either green or yellow, including the earth wire. Keep in mind that if the wires that your switch is attached to are white or aluminum, you should always have an electrician look at it.
Step 4: Check Box Volume
For this step, please refer to the National Electrical Code Article 314 to help you understand the volume you will need inside your steel box. Having too many wires inside a box can lead to hazards such as short-circuiting, fires, and over-heating. Hence, it is essential to adhere to the boxes’ size to ensure you and other people stay safe.
Step 5: Pay Attention to the Gauge of Wire
Choose the gauge of your wiring accordingly. Usually, 20-amp circuits are wired with 12-gauge wires, and 15-amp circuits are wired with 14-gauge wires.
Step 6: Test the Ground
There’s either a green ground screw or a green grounding wire when it comes to modern dimmers. Either one of these needs to be connected to a grounding source (if there is a grounding source present).
If your wiring has a plastic casing, you will have copper wires requiring getting hooked up with the dimmer switch. In some cases, metal conduits are present for this purpose.
Check for grounding with a neon voltage tester. If there is ground present, pop a short ground wire to the metal box or use a grounding clip. Now, connect this to the dimmer.
Ensure that there is no ground present in cases, utilize a plastic cover plate and make sure there are no metal parts exposed. Now, test again and turn the power back on. Your box is grounded if the tester lights up by popping your voltage tester leads between the screw terminals and the box.
Step 7: Turn the Power Off
After you’re done checking for grounding, TURN THE POWER OFF.
Step 8: Add your new dimmer
For this step, with the help of a screwdriver, you will have to press 6 inches of copper wire along with a grounding clip onto the box.
To give the clip a little clearance, you will have to cut away some drywall. Bend the wire back onto the clip by using a needle-nose plier. To make sure there is no interference with the dimmer switch, pinch it down tightly.
With the help of your wire cutters, cut the ends of the wire off. Strip around 3/8-inch of insulation off the ends so you can proceed to connect the wires.
Step 9: Connecting the Wires
Connecting the right dimmer is one of the most crucial steps of the entire process. If your dimmer has wires that are stranded, you will need to hold the wire tightener in such a way that the stranded wire stands up from the solid wire by about 1/8-inch.
Match the sizes and number of wires to the connectors. By twisting the connector clockwise, fit the wires tightly. In case your dimmer has screw terminals, you will need to strip off 3/4-inch of insulation from each wire by forming a loop with the help of your needle-nose pliers.
After popping this loop around the terminals, close it up using your pliers. Once you’re done, tighten up the screws.
Step 10: Put the Cover Plate back on.
The last step would be to neatly fold up the wires and putting them back in the box. After doing so, screw the dimmer onto the box and install the cover plate. Turn the power back on and test your newly installed dimmer!
Now you will be able to adjust the brightness of the lights in your home easily and reduce the amount of electricity you use. As a result, this will reduce your electric bill in the long run.
