If you’re looking for a way to keep your bathroom fresh and well-lit, a bathroom fan with light is the perfect solution. However, if you’re not an electrician, figuring out how to wire it can be tricky. Fortunately, we have you covered with this step-by-step guide and wiring diagram. So, let’s get started!

What You’ll Need

Before you begin, make sure you have all the necessary tools and materials. Here’s a list of what you’ll need:

Tools Materials
Screwdriver Bathroom fan with light
Wire strippers Cable connectors
Wire nuts NM cable (12/2 or 14/2)
Electrical tape Light switch

Step 1: Turn Off the Power

Before you start wiring your bathroom fan with light, it’s important to turn off the power to the circuit to ensure safety. You can do this by flipping the circuit breaker or removing the fuse that controls the bathroom circuit.

Once the power is off, use a voltage tester to confirm that there’s no current running through the wires. This will ensure that it’s safe to start working on the wires.

Step 2: Mount the Fan

Now that you’ve turned off the power, it’s time to mount the fan. Locate the area where you want to install the fan and cut a hole in the ceiling for it. Make sure to follow the manufacturer’s instructions on the size of the hole.

Next, attach the fan mounting bracket to the ceiling joist using screws. Then, hang the fan motor onto the bracket using the provided screws. Finally, insert the fan cover onto the motor and secure it in place.

Step 3: Wire the Fan

Now that you’ve mounted the fan, it’s time to wire it. Start by stripping the end of the black (hot) and white (neutral) wires on the fan motor. Connect the black wire to the black wire in the NM cable using a wire nut. Similarly, connect the white wire to the white wire in the NM cable using a wire nut.

Once you’ve connected the wires, use electrical tape to secure the wire nuts and prevent them from coming loose.

Step 4: Install the Switch

Now it’s time to install the light switch. Locate the area where you want to install the switch and cut a hole in the wall for it. Make sure to follow the manufacturer’s instructions on the size of the hole.

Next, run the NM cable from the fan motor to the light switch box. Strip the end of the black and white wires in the NM cable and connect them to the matching terminals on the light switch. Make sure to follow the manufacturer’s instructions on how to connect the wires.

Step 5: Wire the Light

Finally, it’s time to wire the light. Strip the end of the black and white wires on the light fixture. Connect the black wire to the black wire in the NM cable in the light switch box using a wire nut. Similarly, connect the white wire to the white wire in the NM cable using a wire nut.

Once you’ve connected the wires, use electrical tape to secure the wire nuts and prevent them from coming loose.

FAQ

Q: Can I use a bathroom fan with light on the same circuit as other bathroom appliances?

A: Yes, you can use a bathroom fan with light on the same circuit as other bathroom appliances. However, it’s important to make sure that the circuit can handle the load of all the appliances. You should consult a licensed electrician to ensure that your circuit is properly sized.

Q: Can I install a bathroom fan with light in a shower stall?

A: Yes, you can install a bathroom fan with light in a shower stall. However, you should make sure that it’s rated for use in damp or wet locations. You should also follow the manufacturer’s instructions on installation and wiring to ensure safety.

Q: How do I know if I have a 12/2 or 14/2 NM cable?

A: The number in the cable designation (12/2 or 14/2) refers to the size of the wire used in the cable. 12-gauge wire is thicker and can handle more current than 14-gauge wire. To determine which cable you have, look at the writing on the cable jacket. It should indicate the cable type and size.

Q: Can I install the light switch outside of the bathroom?

A: Yes, you can install the light switch outside of the bathroom. However, it’s important to make sure that it’s located in a convenient and accessible location. You should also consult local building codes to ensure compliance.

With these steps and tips, you’re now ready to install your bathroom fan with light wiring diagram. Be sure to consult with professionals or licensed electricians, when in doubt. Always prioritize safety and follow the manufacturer’s instructions for proper installation. Happy wiring!
