Use the red wire in the 3-conductor cable to put the light and fan on different switches. Connect the hot wire from the fan to the black wire from the switch and the hot wire from the light to the red wire from the switch. The hot wires in the unit may be colored differently.

How do you wire a bathroom exhaust fan with light?

Quote from the video:
Quote from Youtube video: Box this is hot only when the switch is on and then we have the blue wire which goes to the light. And we have the black wire that goes to the fan. So we just flip up all three of the connectors.

Can a bathroom fan and light be on the same circuit?





This is acceptable. Many bathroom fans include lights with the intention of both being wired to one switch on the same circuit. They can also be wired separately to different switches.

How do you wire a bathroom light and fan to one switch?

Quote from the video:
Quote from Youtube video: Together now here we have a blue wire and a black wire one is for your light and the others for your fan. And if you're going to run them on one switch what you'll do is take your black wire bunch

Does a bathroom fan need to be on its own circuit?





Bathroom Circuits



If the vent fan has a built-in heater, it must have its own 20-amp circuit. This is called a “dedicated” circuit because it serves only one appliance or fixture. Heat lamps, wall heaters, and other built-in heating appliances may also require dedicated circuits.

What is the red wire in a bathroom exhaust fan?

Use the red wire in the 3-conductor cable to put the light and fan on different switches. Connect the hot wire from the fan to the black wire from the switch and the hot wire from the light to the red wire from the switch. The hot wires in the unit may be colored differently.

Do bathroom lights need to be GFCI protected?

You might not be aware of it, but your bathroom lights could pose a safety hazard in the event that you have an electrical short. This is because GFCI (ground fault circuit interruption) protection is only required for outlets and switches, not light fixtures unless they are above the shower area.

What kind of wire do you use for a bathroom fan?

Most bathroom ventilation fans use a 15-amp circuit breaker and 14-gauge wiring. Due to the increased power drawn, fans with heaters usually require a 20-amp circuit breaker and 12-gauge wiring.

Can bathroom GFCI and light be on same circuit?



The main rule in 210.11(C)(3) states that the branch circuit provided to supply the bathroom receptacle outlet(s) shall have no other outlets. No lighting outlets or other equipment can be fed from the same circuit feeding the bathroom receptacles.

Can a fan and light be on the same switch?

People frequently wire a ceiling fan with a light to two light switches. That way they can control the fan with one switch and the light with the other. But what if the room has only one switch and you have to wire a ceiling fan with light to one switch? You can still do it.

What kind of light switch do I need for a bathroom fan?

Thanks! If it’s a typical small one speed bathroom fan you can use any on/off switch that matches the load specs; just don’t use a dimmer switch intended for lights. If it’s a large ceiling fan or a variable speed fan, then you need to use one of the purpose – built fan switches: both Leviton and GE make these.

How do I wire a light switch?



Quote from the video:
Quote from Youtube video: Usually the switch will have an indicator should say top or just read the the words and read em right side up that'll be the top of the light switch okay. So the black wire will come in and it.

What are the 3 wires on a light switch?

With a three-way switch, three wires connect the pair of switches—two black “traveler” wires and a third “common” wire. When the circuit’s power is turned on, any of these may be “hot,” depending upon how the switches are toggled.

Does it matter which wire goes where on a light switch?

It doesn’t matter as long as you do it the same on both switches. So, if you connect it to the upper right terminal on one switch, connect it to the upper right terminal on the other switch. Connect the second traveler wire to the terminal opposite the red wire terminal.

What happens if you wire a light switch wrong?

But here’s the catch: If you connect the circuit wires to the wrong terminals on an outlet, the outlet will still work but the polarity will be backward. When this happens, a lamp, for example, will have its bulb socket sleeve energized rather than the little tab inside the socket.

Can wiring a light switch wrong cause a fire?



Usually, a broken or failing light switch isn’t a fire hazard itself, but it can overheat if the contacts or the switch wear down. Sometimes a bad light switch can cause other components on the circuit, such as a bulb, to become a fire hazard by causing an intermittent current.

Which wire is hot on switch?

black wire

Here’s a rundown of electrical wires: The black wire is the “hot” wire, it carries the electricity from the breaker panel into the switch or light source. The white wire is the “neutral” wire, it takes any unused electricity and current and sends it back to the breaker panel.
