Wiring an Outside Light to Two Switches

If you want to control an outside light from two different locations, you can achieve this with a three-way switch setup. This allows you to turn the light on or off from either switch. In this article, we will walk through the process of wiring an outside light to two switches in a clear and straightforward manner.

Tools and Materials Needed

Before you start, gather the following tools and materials:

• 14/2 NM cable (with ground) for the connection
• Two three-way switches
• One outside light fixture
• Wire nuts
• Electrical tape
• Screwdriver
• Wire strippers
• A voltage tester
• A drill (if mounting is necessary)

Safety First

Before beginning any electrical work, ensure your safety. Turn off the power at the circuit breaker to prevent any accidental shocks. Use a voltage tester to verify that the power is off before you touch any wires.

Wiring the Switches

Step 1: Installing the Switch Boxes

Start by determining where you want to install the two switches. Make sure the locations are convenient for access. Use the drill to create holes for the switch boxes if necessary. Ensure they are at a comfortable height, typically around 48 inches from the floor.

Step 2: Running the Cable

Run the 14/2 NM cable between the light fixture and the two switch boxes. You will need to run:

• One cable from the first switch to the second switch.
• Another cable from the second switch to the light fixture.

Step 3: Connecting the First Switch

In the first switch box, connect the wires as follows:

1. Connect the black wire (from the power source) to the common terminal on the three-way switch.
2. Connect the red wire between the first switch and the second switch to one of the traveler terminals.
3. Connect the white wire (neutral) from the cable that runs to the light fixture to the other traveler terminal.

Step 4: Connecting the Second Switch

In the second switch box, do the following:

1. Connect the red wire (from the first switch) to one of the traveler terminals.
2. Connect the other traveler terminal to the black wire going to the light fixture.
3. Connect the white wire (neutral) from the incoming cable to the light fixture.

Step 5: Wiring the Light Fixture

At the light fixture, connect the black wire from the switch to the black wire of the light fixture. Connect the white wire from the switch to the white wire of the light fixture. Lastly, connect the ground wires. Ensure all connections are tight and secure.

Final Steps

After all connections are made, neatly tuck the wires into the switch boxes and attach the switches and fixture to the spots you've chosen. Turn the power back on at the circuit breaker and test the switches to make sure they control the light as expected.

Congratulations! You've successfully wired an outside light to two switches. Enjoy the convenience of controlling your outdoor lighting from multiple places. If you choose to undertake any electrical work, always prioritize safety and consult with a professional when in doubt.
