Bathroom Fan and Light on Separate Switches

How to Wire a Bathroom Fan and Light on Separate Switches

Bathroom lighting and ventilation are always a concern. You must have a functional bathroom fan to remove moisture from the house. For optimal lighting, you may want to add a light switch for your bathroom lighting. The common bathroom fan is powered by a single switch. Anyone will watch how to wire a bathroom fan and light on separate switches.

If your bathroom fan and lighting share a switch, you’re in for some big surprises. You can select the fan and light wiring separately. Then you will have more control over each one. It will also be able to flip into one to use one or both at your convenience.

Before working on any electrical wires, there is hazardous smoke coming out of the glue or paint. To avoid these, make sure your work area has proper ventilation. Next, make sure you turn off the power supply to the bathroom. No one is likely to use it when you are working on a light fixture. We will assume that these two basic requirements have been met before we proceed. It is not difficult to put lights on bathroom fans and separate switches unless you remember these three rules:

1. Always turn off the breaker that controls the circuit you are working on. That no one can accidentally restart it while you are working.

2. Always check the wires with a voltage tester or continuity tester before you enjoy it. 

3. Never work in a live circuit unless absolutely necessary.

How to Wire a Bathroom Fan and Light on Separate Switches

Things You Will Need

Light a bathroom fan and separate switches. To light it on a separate switch, you will need some tools.

  •  A fan switch
  •  Wire stripper
  •  Pliers 
  • Staple gun, 
  • Clips
  •  Electrical tape,
  •  Shims screwdriver
  • Drill hole
  •  Level pencil pen
  • Cable nut 
  • Light socket.

In addition to the usual equipment, you will need a bathroom fan control switch. The cost of control can vary according to the number of circuits it controls. This can usually be as high as 20 to 50 per circuit. The bathroom light switch can be on the wall plate.

The bathroom fan, lights, and switches are all fit and it is ready to do its job. Just turn on the circuit breaker and flip the switches to test them before making any permanent connections. Though you prefer to control them with a separate switch, you will need two three-way switches. A switch with three-wire or four-wire nuts, and a total of six boxes.

When you are ready to install the fixture. Then apply a large amount of waterproof electrical tape to the empty copper wires from your fixture. Wrap the tape clockwise around the wire. This helps ensure that you have connections that will not leak or erode.

Most single-switch bathrooms have a combination fan and light switch. When the light is off, it will slow down or even turn off. A little more wiring than most installations is required to attach the wire to a bathroom fan. To control it by two separate switches.

Rules of Application

 bathroom fan and separate switch

Step 1

To turn on a bathroom fan and separate switch, turn off the power. To circuit at the main breaker and remove the old fan switch. Cut the wires in the switch box and pull the wires (black or red) and ground wire (white) for power. Whether you are installing a new switch or replacing an old one. You can install a new fan, and use a 14-gauge wire for 120 volts. Like black or red hot wire, neutral as white and green as a ground wire. If an Aadhaar replaces an old switch, use a 12-gauge wire rated for at least 150 volts.

Step 2

Connected to the large “com” terminal of the switch and the black wire from the ceiling fixture. Also connected to the small “normal” terminal of the switch. The black wire from the ceiling fixture is then connected to one of the two screw terminals of the switch. A wire nut does not control the fixture itself or control the switch. The next task is to connect both wires from the ceiling fixture: black, red, blue and white.

These are attached together with a wire nut as well. Reconnect the green heated ground wire connecting any screw terminal on both switches with a wire nut. To turn on the power in your main service box, remove both switches, remove your existing wall plate. It controls both switches, replace it with a simple dandy double switch plate.

Step 3

Look for an existing switch box near the ceiling fixture. Use plastic-pressed, copper-covered wiring to connect the electrical junction box to the fan. Use insulated wire nuts with circuit breaker panels. It can handle at least 15 amps. There is no switch box near the light fixture.

Then run a new piece of wire with the flexible electrical wire in a box near the fixture from the source. Snatched up in 12-inch increments. The wire nut for connecting these two pieces is part of a simple electrical supply kit. Make sure. Inside this connection box all bare wire ends.  Soldered in place and covered with a protective coating of clean nail polish. Then attach the black wire nuts to each other on both sides of this box.

The Mains Electric Supply

The Mains Electric Supply

Considering all the factors, the design of the house and the line voltage control as far as careful arrangement. Consideration will keep your bathroom peaceful for many years.

Installing bathroom fans and lights in different switches is a common question that bothers homeowners. To renovate or transform only existing space. In this article, I will show you how to wire a bathroom fan and light on separate switches.

Once you have detected the switch and breaker, check that the breaker box has power off and disconnect the wires. Assuming you have a new fan, there will be two wire leads. Black wire lead for your light and white wire lead for your motor. Connect these wires to the appropriate connections on each button. Then attach a black wire to each of your ground connections. Finally, tie the rest of the wires together using tie wire or electrical tape. If you want to control the bathroom fan or the lighting yourself, this is a great way to save money.

Turn Off the Switch

Turn Off the Switch

A bathroom fan can be wired to a light fixture, wired to a separate switch from the light. If more than one switch is connected to the same cable, all the switches will trip at the same time. It often flows into an electrical box in your home. When you don’t want it. Though the fan leaks or obstructs, you can finish with flooded walls or ceilings. The biggest mistake homeowners make when wiring the bathroom is to leave a switch on to control the lights and fans. This can be dangerous, as there is nothing to stop someone from turning off the lights. But forgetting to turn off the fan. Some experts recommend keeping an extra switch near the fan.

Using the Right Wire

Many bathrooms have a light switch and a fan switch. These switches are often side by side so that one fades or multiple switches. You replace the original light fixture or install a new one. See that the wires are everywhere without any switch. Everybody can add a light and a fan switch to complete the task. This is a simple wiring project.

Using the Right Wire

To turn on the lights in a bathroom fan and separate switch, first, turn off the bathroom power with a circuit breaker. Connect your new wire, the black cable of the fan to a toggle switch. The white cable of the fan to a second toggle switch. Then connect the black wire of the light fixture to the remaining two-way switch. The white wire to one of the poles of the other switch. Make sure this switch is compatible with your first two switches. “

All wire application

When wiring a bathroom fixture, it is important to use heated wires. Many times inexperienced electrical experts will run one uninsulated cable for the bathroom fan. Another uninsulated cable for lighting. In this example, we are ‘running new wires from the switch to the ceiling box. If you do not have enough wires, use an extension wire to reach the ceiling box.

When lighting a bathroom fan and separate switch, use a 14-2 UF, NM or AC electric cable to connect the light button and fan terminal. The word 14-2 means 2 hotlines coming out of the box. Then you have 2 heated neutral wires and finally, you have 2 ground wires. Remember to add an outlet box between any of your blank cables touching each other. Place the casing on the end of the wire. Thus, if something is pushed or moved, there is no possibility of “shock”.

You’ll Need to Make Pigtails

For a bathroom fan and light cable, we’ll start by explaining how to make a braid. Try mounting the ceiling box first. A “pigtail” is usually a small piece of wire connected to a switch or receptacle. The circuit is then split again so that it looks neat and protected from tampering.

To electrical circuits using a standard three-slot receptacle outlet. Here’s how it works: A four-wire power supply from its electrical panel to the ceiling electrical box. The cable has two wires (hot and neutral) and a ground cable in the center.

Converting Switch

Converting Switch

Remove the Light Globe

Remove the light globe Turn off the power source from your light source. If you have a switch on your fixture, flip it over. Most bathroom fans have three wires, one for the fan. Though your bathroom fan does not have a fan and separate switch for lighting, you will need to remove the light globe first. Access to your bulb socket and cable connection. Reach inside the fixture with both hands and open the globe.

Remove the Wire Connectors

Removing the cable connectors is a fairly simple process. First, turn off the circuit breaker, then remove the cover plate of the wall switch. Using a voltmeter. Check if the power is off before removing any of it. After checking with the voltmeter you can now disconnect the wires from their posts.

The next step is to remove the old cable connectors from the switches. You can clip them or just stick the wires. To pull the cable off by their hands. Next, you need to twist the two wires together at this point. Divide a piece of white wire 6 inches long on both wires. Splice on the existing black and white braids connected parallel to the switch.

Use the Housing Box

Use the Housing Box

Turn off the circuit power to the main service panel before starting work.  Then install an easily accessible single-pole switch to control the power of each bathroom fan. Run a cable from the switch to the fan housing box. Ensure that each leg of the cable carries an equal load. And the cable does not extend more than 12 inches before the box. During installation, you will need to drill a hole to run the power cable from your breaker box to your home’s electrical system.

Part I – Fan Wiring: The last step in our electrical project is to connect the fan and light switches to the new circuit. This is a fairly simple task, as you will use a 4-wire cable that has a live cable. Like two black wires and a ground cable. Connected to the green ground screw of the switch box. To connect to the metal junction box. The white wire of our cable connects to the white neutral screw of the switch box. When both black wires are joined to a cable nut and then to the brass screw terminal on one side of the fan. Wrapped with electrical tape and pushed inside your box for protection.

Wire the Cable to Your Bathroom Fan

Why aren’t you replacing a faulty bathroom exhaust fan or installing a new one to increase airflow? You need to understand the process of wiring it in the main electrical box of a house. This article will explain cable size and quantity, cable configuration, switch placement and other important electrical considerations.

Wire the Cable to Your Bathroom Fan

To light your bathroom fan and separate switch, you need a cable that powers both the fan and the light. Two terminals at one end of the cable and three wires at the other end. Attach the red or black wire to the terminal with two screws. Mark this cable with tape or a label. Because it connects to the switch that controls both devices. If necessary, return to the electrical panel and turn off the power to the circuit breaker slot in your bathroom.

The first thing you need to do to install a vent fan in any bathroom is to climb the attic. Before you begin, make sure all circuit breakers in your home turn off. Also, make sure the power on the service panel turns off. Then remove and label the cover plate from the ceiling light switch. Turn on the light and pull the switch on the wall. Turn on the ceiling fan.

Use the Wire Stripper

Use the Wire Stripper

In this paragraph, I will show you how to wire a bathroom fan and light on separate switches. First, we use the wire stripper tool to remove the outer sheath from the Romex cable. We will then cut the individual small wires with a diagonal cutting plier. We install a cable connecting cap on each cable. Then strip one end of each cable using the cable stripper tool. We bring the four wires together, twist them together and then crimp them with our crimping tool.

The ring terminal system connects to the ceiling fan with three screws. We tighten them one by one. Today we installed white and black wires from the ceiling box. To use for bathroom lighting and connected our ground cable to the grounding bar of the ceiling box. This way we can turn on two lights in your bathroom with two switches, for the fan and two lights.

Attach Black, Neutral, and White Wires

Attach Black, Neutral, and White Wires

To convert your bathroom light from a single switch to a separate switch. To attach the black wire to the hot screw terminal, attach the white wire to the neutral screw terminal.  Attach the gray, green or blank cable to the load screw terminal if three wires are present. 

You can use a wall switch like the FA-13. For fan wiring, run a 3-wire cable from the switch to the ceiling box. That connects to the black and white wires. You want to label each wire with tape so that they are separate. Current is carried from the source of electrical energy to the lights and fans through the “knock out” wires of the power box. The wire that carries current in the light is called hot cable, or black cable. The wire that carries current to the fan is called load wire or white wire.

Restore Power

Restore Power

After flood damage, electrical units may become waterlogged, rusted, or destroyed due to moisture. And if you spot a problem with the electrical wiring that runs toward your bathroom fan or light unit. Don’t try to fix it yourself without knowledge. Instead of using pen and paper, which is wrong and unreliable in this situation. Learners can use a digital recorder such as a 16GB voice-activated digital audio recorder with a microphone.

For wiring a separate switch to a bathroom light and fan. Starting by turning off the power in the circuit breaker. Then, connect the black wire from the ceiling box to a black cable in the bathroom fan. Connect the white wire to the white wire of the bathroom fan from the ceiling box. Connect a heated stab-lock connector to the black “hot” cable. Comes in the switch box representing the power in a branch circuit protected by a 15A breaker. Connect another stab-lock connector to this hot power cable. To the two wires coming out of a double-pole switch. Connect an insulated wire with an incoming white neutral cable and an outgoing neutral, or ground. Wire with a ground screw in a branch circuit protected by a 15A breaker.


There are multiple options for switches, 2-way to 3-way and even dimmer. Just remember how the wire is threaded through the existing box. Screw everything in the right place, put your cover plate back on and go away knowing you fixed it.

When turning on the light in the bathroom fan and separate switch. You still make sure that the light works in wet places. It is also possible to install individual switches with a dimmer control mounted on one side of them. For added convenience, you may have a motion or humidity sensor. That will turn the fan on or off as needed.

We’ve shown you a variety of ways to use your bathroom fan and lighting wiring to see how to wire a bathroom fan and light on separate switches. Starting from the switch towards the fan. If these different measures confuse you. I will summarize them in three simple thoughts. First, if you can cable the switches in series, do it. One advantage of this is that a single switch will control both circuits. Second, in most cases connecting the switches parallel to each other is delicate and very easy to do. Finally, when you want to cable your switches in a room separate from the fan’s position, I recommend connecting the two switches together in a series of wires.
