Light Switch Wiring – How to Install a Three Way Switch and Light the Ceiling Lights

Home lighting is something that can really add to the ambiance of a room, but if you’ve never installed light switch wiring before, you may be at a loss at how to proceed. Wiring is one of those things that you either have to know a lot about or you figure out on your own. Luckily, it doesn’t take a great deal of expertise to get this job done. Often found right in front of your door, switches enable you to control wall sconces, ceiling-mounted lights, and other electrical outlets with just a simple tap or swipe. While it may sound like magic, it is all just a matter of knowing how your light switch wiring really works, which includes information on end-switch and power-through switches as well.

Most home lighting is done with electrical power; this is usually a standard 120v household plug. In many cases, light switch wiring is done with separate wires for light bulbs as well as an outlet. The separate wires are often marked with individual sockets, but you’ll often see a single white wire that is used for power and a red wire that is used for ground. There are usually three wires, so you can be sure you understand what is going on with your wiring before you start. Once you understand what is going on, the job becomes a lot easier.

To begin your light switch wiring, you need to find your electrical panel, which is typically a molded plastic rectangular box with a light fixture outlet box in the middle. The outlet box serves as the entry point for power to the actual light fixture. To determine if your panel is accessible without removing your fixture, you can look inside the outlet box. If you can’t access the entire panel easily, you may need to install a wall anchor. Be sure you follow any local building codes for your area. If you aren’t sure how to do this, search online or contact a professional electrician to help you.

The next step in your light switch wiring is to use a standard ground connections diagram to identify the three wires. These are typically color coded to help you identify what each wire is for. For example, blue means power and red means ground. Be sure to match the colors to the typical ground connections diagram that is provided by your power company.

Next, you’ll want to attach the power cord from the light fixture to the three-way switch wire diagram. You’ll want to connect the ground wire to the negative connection on the cable just like you would with the typical ground connection diagram. After you have connected all three wires to their respective outlets, you should then feed the supplied 20 pin power cord through the light switch wiring receptacle. Lastly, push the three-way switch into its slot and snap it into place.

Finally, you should feed the terminated cable into the bottom of the light switch wiring receptacle outlet. Make sure the black and white wires are feeding into the same receptacle outlet. Then you simply repeat your steps from above, but this time using the neutral wire as the ground wire. After you have connected the three wires, you should attach the black and white wires to their corresponding receptacles on the ceiling electrical box. Finally, push the three-way switch into its slot and snap it into place.
