Do ceiling fans require any special wiring and are they difficult to fit? A. A fan with or without lights can be wired into an existing lighting circuit and is a simple DIY job. If you are in any doubt then consult a qualified electrician.
Appliances That Do Not Need a Dedicated Circuit
Many compact or portable appliances do not need dedicated circuits. Examples include portable fans, ceiling fans, countertop cookers, food processors and small space heaters.
There's really no problem in replacing an existing light fixture with a ceiling fan in terms of the electrical needs. But what you really have to be careful of is to make sure the electrical box that the light fixture is attached to will support the extra weight of the ceiling fan.
You need to use a new run of three-conductor wire (denoted as “14-3” – check your local code for the specific gauge). Connect black fan wire to the black ceiling wire. Connect the blue wire to the red wire. Connect white wires together.
II believe the average fan runs at 75 watts, by code you can use up to 80% of the 15 amp breaker. This will put you at 1200 watts of usable current on the 15 amp breaker. So you would divide the 75 watts into the 1200 and you would get 16 ceiling fans.
Practical Installation Tips
On a 15-amp circuit, you can safely run up to 144 LED lights, assuming each light consumes 10 watts. Always take into account other devices sharing the circuit, and ensure you leave room for a safety margin to prevent circuit overloads.
A standard ceiling fan with a 3-blade running on 120V would draw around 0.6 to 0.8 amps of current.
Wiring Ceiling Fan and Light With One Switch
Connect white wires together. Connect black wires together. Connect the lighting wire, typically blue, to the black fan wire and the black ceiling wire. Tuck the wires back into the box.
Yes, but it is better to run three wires in case you wish to “wall switch” the fan and light separately. This could also be done with a remote control, by purchasing a remote operated ceiling fan fixture.
Adding a Ceiling Fan with Lights
Many ceiling fans include light kits for illumination. Adding lights requires an additional hot wire, as well as neutral and ground: Black (hot) for fan motor power.
A fan with or without lights can be wired into an existing lighting circuit and is a simple DIY job.
Capping electrical wires is the safe, code-approved way of dealing with terminated electrical cables. It's important to cap electrical wires for fire safety, to prevent electrical shocks, and to prevent short-circuiting or damage to the electrical system.
Yes, you can install a ceiling fan where a standard light fixture is, and you might not need to add new wiring. However, you'll need to ensure the electrical box supporting the light is strong enough to support a ceiling fan, as it will be heavier than the existing light fixture.
You might want to install a dedicated circuit for your outlets to avoid sharing the same circuit as your lights if any of the following are true: Your circuit needs more amps than the max capacity: Outlets require more amps to power than light fixtures, so make sure your circuit can handle the capacity.
No, ceiling fans don't have to be hard wired.
You can just cap the red wire with a small wire nut and ignore the switch on the wall. Pull and twist and the wires will likely pop out (the reason backstabs like this are not reliable). If they're torn up or won't come out then snip and restrip.
It entirely depends on the wattage and therefore the amperage used by all the lights put together. On a 120VAC circuit, 18 100-watt light bulbs would add up to 1800 watts, which is 15 amps, which is the load limit of 14 gauge romex wiring.
14–2 wire is allowed for a 15 Amp circuit, and at 120 Volts, 15 Amps x 120 volts = 1800 volt-amperes. So that would allow ten (10) receptacles, you would probably derate that to eight (8) for an 80% safety factor.
Black wire is for the fan. Blue wire is for the light, if light is included with the fan. White wire is neutral. Green wire is for the ground.
The red wire is generally used to switch the fan on and the black for the light in the fan, or vise versa, using 2 switches in the wall. If you have a remote receiver in the fan housing it takes the place of the 2 wall switches so you only need 1 hot wire (in this case black) to power the remote receiver.
Pink and violet are less prevalent but can be used as travelers or switch legs, or as dimming control wiring for lights. Brown conductors are used primarily in three-phase services, but you could see them in your home, too.
Ceiling exhaust fans, overhead lighting and cabinet lighting can be on with other lighting up to a maximum of 12 fixtures on one circuit.
Although it could run for over a 24 hour period, it is still best to turn off your ceiling fan when you are at work or out of the house for an extended time to give the ceiling fans' motor a rest and reduce electricity use and cost.
