When it comes to wiring a 3-way switch, there are a few different configurations that you can use depending on where the power source is located. One common setup is having the power come into the light fixture first before going to the switches. This is known as power at light wiring. In this article, we will discuss how to wire a 3-way switch with power at the light.
In a power at light setup, the power source is connected to the light fixture before heading to the switches. This means that the hot wire from the power source will connect to the black wire of the light fixture. The white neutral wire will then connect to the white wire of the light fixture. From there, two traveler wires will run from the light fixture to the switches.

To wire the switches, the traveler wires will connect to the brass screws on each switch. The black wire that is connected to the common screw on one switch will then connect to the common screw on the other switch. This creates a continuous circuit that allows you to control the light from either switch.
It’s important to make sure that you properly identify the traveler wires when wiring the switches. These wires are typically a different color than the hot and neutral wires, such as red or black. It’s also a good idea to label the wires with tape to ensure that you connect them correctly.
Once all the wires are connected, you can install the switches in the electrical boxes and secure them in place. Make sure to test the switches to ensure that they are working properly before closing up the boxes. If everything is wired correctly, you should be able to control the light from either switch.
In conclusion, wiring a 3-way switch with power at the light is a common setup that allows for convenient control of a light fixture from multiple switches. By following the proper wiring diagram and taking the time to correctly identify and connect the wires, you can successfully install a 3-way switch in your home.
