Bathroom fan installation is important in homes to reduce excessive moisture that can cause damage to paint and walls. The time to plan for a bathroom fan system is while the wall and ceiling framing members are still exposed from remodeling or new construction.
Most bathroom exhaust fans have a metal box that has to be installed between the ceiling rafters or floor joists. The bathroom fan will fit into this box as part of the finish work or appliance installation.
The ceiling or attic is the best place to run the exhaust vent. A dryer vent hose makes the best vent because of its flexibility and low cost. One end of the flex hose attaches to the outlet in the metal box with a large hose clamp. The other end of the exhaust vent will lead to an opening in the roof or the soffit.
There are different types of exhaust fans available for different needs. If its a simple bathroom fan, then you can use a single light switch to turn it on and off. If theres a light and heater with the fan, then youll need to use three different switches to control each component. There are some nice looking triple switches that work well for these types of fixtures.
Be sure to turn off the breaker at the breaker box and make sure that other people in the house know what youre doing with electricity.
Lets say were wiring a light and fan combination. We can use 12-3 NM sheathed cable which has three wires and a ground wire. From the switch well need to have the circuit wires to provide the power. We will run the 12-3 cable from the switch box to the fan. There will be a red wire, a black wire, and a white wire, along with a copper ground wire.
Well use a double light switch that fits into a regular-sized switch box. The 12-3 Romex cable that runs from the fan box to the switch can be wired first if you want. You will need to connect the red wire to one of the hot screws on the switch. The black wire can be connected to the other hot screw usually on the same side of the receptacle.
The switch will also have a screw that attaches to the house current or circuit power. The black wire from the power circuit will connect to the switch giving it power. The white wire from the house circuit power and the white wire from the fan can be combined together with a wire nut. You can also combine the copper ground wires together with a wire nut. Tuck all the wires into the switch box neatly and secure the switch in place with screws.
Next, youll do the wiring for the light and fan with the 12-3 cable. There will be four wires with this fixture that control the different components. The red wire from the fan will connect to the red wire from the 12-3 Romex cable. There will be a black wire from the fan light assembly. It will connect to the black wire from the power cable. The white wire will be joined together with the other white wire and the ground copper wire can be joined together with the cable ground wire with a wire nut.
Install the fan assembly into the metal box with the attachment screws. Switch the breaker on to make sure that each component works when you turn them on.
