Turning Off Power
To begin wiring a double switch for your bathroom fan and light, it’s important to turn off the power. Start by locating your home’s electrical panel and identifying the correct breaker. Flip the switch to the off position, ensuring that the electricity is no longer flowing to the bathroom.
This step is crucial for your safety and the success of your project. Once the power is off, you can begin the wiring process with confidence, whether you’re a seasoned diyer or a first-time homeowner. Remember, always turn off the power before working on any electrical project to avoid injury and ensure quality results.
Removing Existing Switches
To remove old bathroom fan and light switches, begin by switching off the power. Use a voltage tester to double-check the current. Then, remove the cover plate. Proceed by removing the mounting screws, and then carefully pull the switches out.
Be sure to detach any wires connected to them and label them appropriately. Ditch the old switches and prepare the new ones. With your wires properly labeled, connect them to the new switch. Finally, push the switch into the box and use screws to secure them in place.
Remember to put on the cover plate and restore power to test the new switches.
