Materials and Tools

  • Electrical Wire Stripper: It is a tool that you will need to strip the insulation of electrical wires cleanly without damaging the wire itself.
  • Screwdriver: It could be powered or manual that is used for screwing and unscrewing of the screws. 
  • Electrical Switch: You will also need electrical wall switch that will enable you to turn off and on your ceiling fan.
  • Wire Nuts: These electrical wire nuts will help to fasten two wires, one from the fan and the other from the switch.
  • Electrical Tape: It will allow you to insulate the fastened electrical wires.
  • Wire: To make a connection of the ceiling fan with the switch box, the wire will be needed.
  • Drill Machine: Drill machine will be required to make holes for the switch box and the mounting brackets.
  • Starter Switch Box: It will be used as a starting point for the wire resource.
  • Extra Deep Outlet Box: For housing larger device control such as fan speed control and dimmer switches.
  • Raceway: Enclosed conduit for wires to the ceiling fan from the starter box.
  • Flat Elbow: For the 90 degree turn up the wall.
  • Inside Elbow: For the 90 degree turn to the transition from the wall to ceiling.
  • Mounting Hardware: Mounting hardware for the raceway fittings such as clips, straps, couplings and bushings.   

How to install a ceiling fan electrical box?

In this section of the guide, we will tell you, how to install a ceiling fan electrical box. The first thing that you will have to do is to install a fan switch next to the existing switches. For example you have two switches in a row and you are going to add a third one in that row. Disconnect the breaker and make sure that there is no power in the switches with the use of voltage detector.

Now it’s time to unscrew all the visible screws on the face plate to remove the switches from the box. You can use pry bar and hammer to remove the old box from the wall. After taking your old box out of the wall, Take your new switch box and put it on the wall, where you want your new switches. Please make sure that your new switch box is aligned with the old one. Outline it with the pencil. Now take the saw and cut out the wall to install the new switch box.

Open all the wire openings of the new box to bring the electrical wires into the box. After you cut out the hole, take your box and slide it into the hole. Take the screwdriver and tighten up all the screws. Now you have an installed switch box on to the wall. Use wire stripper to strip the insulation and join the wire together to make connections. Please make sure that all wires are secure. Tuck the wires into the box and install the face plate by screwing it up.

How to Install Raceway Fittings?

Our next step of “how to install ceiling fan without existing wires” guide is to install raceway on the wall. It’s better to use laser level for raceway fittings for proper and clean installation. Turn on the laser and mount it to the starter box to establish a straight laser line. Use this laser line as a guide to make holes for raceway clips. You can use hollow wall anchors for securing the clips.

Using the laser level, find the intersection point of the ceiling joist and switch box. This will be the flat elbow location. Mark the location of the elbow tongue. Measure from the switch box to the elbow tongue and cut the raceway. The raceway should be ⅜ inch more at each end from the measurement. This extra ⅜ inches at each end enables the raceway to slide over the tongue at the box or the fittings.

Now cut the raceway, carefully deepen the cut, and insert bushing at each cut end. Before installing the raceway, slide the elbow onto the raceway. Slide the raceway onto the starter box tongue and tap the raceway into the support clip. Then screw the flat elbow into the wall. Now measure from the flat elbow to the ceiling. In similar fashion, cut ⅜ inches extra raceway at each end. Install the raceway on the wall starting from the flat elbow to the corner of the ceiling where inside elbow base starts.

The next thing that you will do is to fasten the elbow base to the wall at the inside corner. By holding the fan box in position, mark its location with the pencil. Measure the length between the marking of the fan box and the inside elbow. Add ⅜ inches at each end to the raceway, bore the raceway, and insert the bushing. Slide the raceway onto the base of the elbow and then softly tap the raceway onto the support clips.

This will hold the raceway in place along the ceiling to the marking of the fan box. Before mounting the fan box base, be sure to insert the long metal screws through the base and install the hexagonal stud to fully tighten. These screws will be used later to hang the fan. Slide the fan box onto the raceway tongue then screw to fasten the fan box base to the ceiling joists.

Now it’s time to feed the fire into the raceway and connect the devices.Push the wire from the elbow in each direction. Your next task is to attach the elbow caps. Then make the proper electrical connections.

How to install a ceiling fan from scratch?

As you have seen that we have covered how to install a ceiling fan electrical box and raceway fittings till now. Now we move forward to tell you that how to install a ceiling fan from scratch. Firstly, upon unboxing your brand new ceiling fan, you will get Motor head, fan blades, upper canopy, lower canopy, down rod with ball hanger, and mounting bracket for ceiling fan hanging.

Before we move forward, let’s have a closer look at these parts of the ceiling fan and for what purpose they could be used. The Motor head is the main part of the ceiling fan that enables fan to move. It contains the electric motor and called body of the ceiling fan. Fan blades are attached to the motor head or body of the fan. The number of fan blades for various models can be different i.e three or five. These blades are also called wings or paddles of the ceiling fan.

The Upper canopy hides the mounting bracket and ball hanger to give a stylish look. Similarly, the collar cover/  lower canopy covers the junction of body and down rod. Its mounting bracket will be placed on the fan box. And the ball hanger at the upper end of the down rod will be seated on the mounting bracket to hang the ceiling fan from the ceiling. Lastly, the down rod makes a connection between ball hanger and the body of fan.

Now it’s time to figure out how to assemble a ceiling fan. First of all, insert the down rod through collar cover and upper canopy.  Secondly, install the ball hanger onto the down rod by tightening it up. Thirdly, push the wires through the canopies along the down rod. Now, put the down rod into the motor head and tight all the visible screws. Take all the fan blades out of the box and tight each fan blade one by one. Now, your ceiling fan is fully assembled and ready for mounting on the ceiling.

Mount your ceiling fan bracket onto the already installed fan box base that we told you how to install it in the “how to install raceway fittings” section. After tightening up the ceiling fan bracket and hang the ball hanger on the fan bracket. Make a connection between raceway fittings wires and ceiling fan wires and cover them with the wire nuts. Now you can turn your circuit breaker on. Your ceiling fan is ready to rock now.
