How To Install A Ceiling Fan Box New Construction – Looking for a ceiling fan upgrade? Read this step-by-step guide to set up a versatile and stylish device.
1 of 5 Easy Fairly easy. It takes some work to install a certified electrical fan box, but mounting and installing a ceiling fan is very simple.
How To Install A Ceiling Fan Box New Construction
Ceiling fans continue to gain popularity as more homeowners discover significant energy savings throughout the year. In the summer, the ceiling fan creates a cool breeze, which reduces the stress on the air conditioner. In winter, they circulate hot air to keep the room warm.
Can You Hang A Ceiling Fan On A Plastic Junction Box?
Installing a ceiling fan is relatively simple, especially if the space above is accessible from the balcony. However, even if this is not the case, the function can still be performed. Here we will explain how to replace an old lamp with a ceiling fan and a new lamp, in a room without a balcony above. The advantage of this approach is that you don't need to run new cables. The fan connects to the existing wire from the old lamp.
But – and this is very important – you cannot hang the fan from the existing electrical box. They just aren't strong enough to support the extra weight and vibrations of the fan. If you cannot reach the ceiling fan from above, you need to use special brackets and boxes to mount the fan between the beams or, better yet, screw the fan-rated “pancake” box (so called because it is . thin. ) directly into the sky. – roof beams.
Use this formula to find the best fan size for the area occupied by the room (the part of the room that collects the most): Occupied area (in square feet) divided by 4 equals the span of the blade (in inches). The blade goes down slightly for rooms with low ceilings, and wider if the ceilings are high.
Another good rule of thumb is to remember that blade spacing under 36 inches is ideal for spaces under 75 square feet, such as bathrooms and breakfast nooks. Wipers from 36 to 42 inches can be used in rooms up to 225 square feet, such as a dining room. Larger living rooms and bedrooms can handle 50- to 54-inch slats.
Replace Old Ceiling Pancake Box
Make sure the fan's cubic feet of air moving per minute (cfm), measured at high speed, is close to the top grade. Some 52-inch fans, for example, go to 2,050 cfm, while others go to 7,800. Not only do high flow fans provide more breezes, but they have powerful motors that last longer and run more quietly.
For optimal performance, lights should be hung at least 1 1/2 feet from the wall or ceiling where they are installed, 7 to 10 feet from the floor, and at least 8 inches from the ceiling. Do not hang the fan near any lights, as the rotating blades under the lights create annoying flickering.
Tip: Pipe threads contain a factory-applied coating. Do not remove this layer; Keep the tube from unwinding.

Answer: The main thing is the ceiling fan wiring diagram with two switch diagrams. Additionally, I have provided links to several ceiling fan manufacturers for replacement parts and indoor ceiling fan wiring diagrams. Note: Some of the links below are to products that are sold on Amazon. As an Amazon Associate, I earn qualifying purchases.
The ceiling fan wiring diagram at the top of this blog post shows a common wiring method used during home construction in the past.
In this ceiling fan wiring diagram, the blue wire on the ceiling fan is connected to the LOAD side of the wall switch to control the light on the fan. The black fan wire is connected to the LINE so that the fan pull chain switch can control the fan motor independently of the wall switch.
Ceiling Fan Tips
If you want to change the cable in the electrical outlet that controls the ceiling fan, go to the blog post here, which has a photo that shows the replacement of the outlet of the switch to heat it so that it connects to the fan of the ceiling to two switches on the floor. wall
Another blog post here covers rewiring a ceiling fan electrical outlet using a metal switch box.
It is not uncommon for the white wire to be used as a hot wire or LINE wire in an electrical switch. However, the white thread must be re-selected in a color other than white, gray or green. I have rolls of electrical tape in several colors that I use for re-identification. Some electricians use a permanent marker to change the color of the wire.
With new home construction, the National Electrical Code requires that a neutral conductor be installed in many electrical box locations for wall switches. Having a neutral gives you the option of using electronic devices instead of standard wall switches to control ceiling fans and lighting. See Section 404.2(C) where the neutral is called a “ground circuit conductor.”

The National Electrical Code also requires that ceiling electrical boxes placed in outdoor areas where ceiling fans may be installed must be rated to support ceiling fans. This is an effective update to Book Code 2020 Article 314.27(C)
I have never seen a wiring diagram for a ceiling fan attached or printed on the fan or motor housing. Most interior ceiling fan wiring diagrams depicting blue wires and black wires are included in the installation instructions.
My post describing the wiring diagram of an electric motor can be useful if you are repairing a fan motor. Ceiling fans are usually a shade motor.
I recommend reading the manufacturer's instructions for installing a ceiling fan before purchasing a fan. It is usually available on the manufacturer's website. There are some links to ceiling fan manufacturers at the bottom of this post.
How Much Weight Can A Ceiling Fan Hold
The following ceiling fan wiring diagram for wall switches can be used in new construction, old remodels and renovations.
Ceiling fan wiring diagram with power for switch box and LOAD wire connected to light blue wire and black wire from fan motor.
The ceiling fan wiring diagram above shows the power first entering the electrical switch box and then the hot and neutral being routed to the ceiling electrical box on the lead wire. This way, the black wire for the headlight motor and the blue wire for the ceiling light are connected to the LOAD wire from the wall switch.
The fan and light are controlled by the same wall switch, but the wall switch can be left off and the fan and light can be controlled separately with a chain switch.

A remote control unit can be added to this ceiling fan. The wall switch should only be kept in the ON position.
If you don't want a remote control, but prefer all the fan control options in place of the wall switch, you should look for a ceiling fan with a wall control that opens the existing wiring. In some cases, this is just a remote control that fits into the wall like a regular wall switch.
Ceiling fan wiring diagram with power in the ceiling box, the blue wire is connected to the red LOAD wire from the wall switch, and the black fan motor wire is connected to the LINE.
Above shows the method that will be used so that the neutral conductor is available in the switch box from the power supply in the rating box of the ceiling fan. The blue fan wire is connected to the red LOAD wire from the wall switch. The black fan wire is connected to LINE. A wall switch controls the light on the ceiling fan and a pull chain switch controls the fan motor independently of the wall switch.
How To Install A Ceiling Fan With A Light
To have a heater and a neutral in the switch box, it is possible to tap the power there to something else like an electrical outlet. The diagram above shows the red LOAD wire from the wall switch connected to the blue wire of the ceiling fan to control the lighting. Fan motor control independent of the wall switch using the fan pull switch chain because the black wire of the fan is connected directly to the LINE.

Three conductor cables are necessary to bring the LINE and neutral along with the LOAD conductor to the ceiling box. The wiring diagram above shows the connections in blue
