Step-by-Step Guide
1. Turn Off Power
The first and foremost step is to turn off the power supply to the circuit that you are working on. This can be done by switching off the circuit breaker or removing the fuse from the fuse box. It’s important to ensure that the power supply is completely off before working on the wiring.
2. Connect the Wires
Connecting the wires is the most critical and complex step of the installation process. For this type of wiring, you will need to run three wires between the switches and two wires to the light fixtures. The wires should be connected in the following way:
- Connect the black wire from the power supply to the common terminal of the first switch.
- Connect the black wire from the first light fixture to the traveler terminal of the first switch.
- Connect the black wire from the second light fixture to the traveler terminal of the second switch.
- Connect the black wire from the second switch to the common terminal of the second light fixture.
- Connect the white wires from both light fixtures to the white wire from the power supply.
- Connect the ground wires from both switches and light fixtures together.
3. Install Switches and Fixtures
After connecting the wires, install the switches and light fixtures in their respective locations. Ensure that the switches and fixtures are securely attached and aligned correctly with their respective boxes.
4. Test the Lights
Before turning on the power supply, test the lights by flipping the switches. If the lights turn on and off as expected, your installation is complete. However, if the lights don’t turn on, you may need to recheck the connections and troubleshoot the problem.
