The act of wiring a bathroom fan and light onto a single switch may appear challenging at first, but it is actually a task that can be accomplished with relative ease if proper instructions are followed. This article will walk you through the process of wiring your bathroom fan and light onto a single switch in an easy-to-follow, step-by-step format.
Therefore, whether you are installing a new fixture or changing out an older one, make sure to follow these instructions for a speedy and straightforward installation. Check to see if an “intercepted” wire already exists or can be installed before you install a separate switch for the lighting circuit that you are wiring in.
This refers to the situation in which a portion of an already-installed circuit has already been wired through another circuit breaker box location so that a second fixture will become operational when either of the first two are activated. If there isn’t an intercepted wire available, install a new grounded electrical box next to the ceiling fan and run new wiring from that box down to your existing opening. In this way, both circuits will be combined into a single path. If there isn’t an intercepted wire available, install a new electrical box next to the ceiling fan.
Wires that have been twisted together to create a single longer wire are referred to as “pigtail wires.” This enables you to connect two cables so that they function as a single cable. Using pigtail wires, for instance, is required in order to connect the wires for the bathroom fan and light to a single switch. This is because the pigtail wires make it possible to connect the fan and light wires together.
Using the pigtail wires, you will be able to splice together TWO wire cables into ONE cable so that you can connect two cables together. The type of wire that is already installed in your wall will determine the color of the wire. It may be necessary for you to twist together about one foot of wires of the same color (for example, white with white) and then give them a good tug to tighten them after you have twisted them together. This will depend on the configuration that is already in place.
Keep in mind that the black wire is the one that is used to send the current back to where it came from.
You will have to make use of some of the pigtail wire if you want to combine two switches that are located in the same box into a single switch. Strip the insulation off of both ends of the pigtail wire that you have just cut off. The piece of wire should be about 6 inches long. After that, wrap each end of the wire around the exposed copper wire on each cable and twist the ends together.
After that, using a wire connector, twist the two white wires, the two black wires, and the two green wires together. This will result in a single lengthy wire that can subsequently be connected to the newly installed switch.
After the wiring has been finished, the next step is to connect the light and the fan. Connect the black wire that is coming from the fan to the black wire that is coming from the light, and connect the white wire that is coming from the fan to the white wire that is coming from the light. At this point, you should finish by joining the two remaining white wires together, as well as the two ground wires together.
1) Ensure that the power is turned off at the main electrical box. Before beginning any kind of work, make sure that the power is completely turned off by using a voltage tester.
2) Take down the outdated ceiling fan and make a careful note of the way in which it is wired into the current electrical system (this can be important information for your remodeling contractor).
3) Using needle-nose pliers, disconnect the wires from the hot side of the switch. If the wires are connected via twisted wire connectors, you may need a small flat screwdriver to release them. It is expected that there will be two wires that are neutral and two wires that are hot, originating from inside the ceiling box and going up through a wire nut into a junction box that is located close to where the old light fixture was. These are the “new” connections you’ll need to make in order to wire your new bathroom light and fan to operate off of the same switch, which will ultimately result in only one circuit. (It is important to note that replacing the connection with a wire nut at both ends is recommended because it improves safety.)
4) Before turning the power back on to test the connections, make sure that all of your wires are securely connected and that the connections are tight.
5) Restart the power supply and look for hot wires touching each other or any other metal object (including your electrical box); if necessary, tighten any loose screws. Before continuing on to the last few steps, check to see that everything is safe. It should be the case that turning off the light on the fan causes the light to turn off, and vice versa. If this is not the case, there may be an issue with the connections that you have made inside the junction box; in this case, you should speak with an experienced electrician.
6) First, remove the cover plate from the ceiling. Next, install your new ceiling fan. Finally, check it out.
When it comes to wiring a bathroom fan and light onto a single switch, you have a couple of different options to choose from.
Although the first method is more difficult than the others, many experts agree that it is the better choice because it requires less wiring.
The second method involves installing a new box next to your existing one and running new wires through both boxes, which results in two separate circuits. However, the installation of this method requires more time and effort in addition to additional materials, which could potentially increase your overall cost.
