Blue or Yellow Wire
In order to control additional functions like separate light fixtures or second fan speed, you can use the blue or yellow wire on a ceiling fan. Sometimes, these wires are used as hot wires to perform specific applications.
You can use purple wires for data transmission and signaling during low-voltage or communication systems.
Like black wires on ceiling fans, red wires are also known as hot wires that provide current flow to the circuit. However, you can use red wires only in three-way circuits. In such a setup, mainly two switches control the same appliance, and the red wire is an alternative power supply.
Things You’ll Need For Wiring a Ceiling Fan
Before you move on to installing and wiring a ceiling fan, you need some tools and materials. Let us acknowledge some crucial materials required to wire a ceiling fan.
You need a voltage tester to measure the current flow before you turn off or on the leading powerhouse. This is an essential tool to verify the power to avoid any casualty.
To securely connect wires, you need wire connectors. Select the specific wire (red for smaller wire, yellow for medium, and orange for larger) to accommodate the various wire gauges.
Fan-Rated Electrical Box
If your ceiling fans don’t feature an electrical box, you must install one first. You can attach the fan-rated electrical box to a ceiling joist for better support.
Usually, you will require an electrical cable that measures triple the conductors to connect the whole circuit. This will ensure smooth operation and power supply.
Wire Staples or Clips
You can use wire staples or clips to join the electrical cable firmly with the ceilings.
Wall Switch or Remote Control
If you want to control the fan and/or light separately or remotely, you may need a compatible wall switch or remote control kit.
Wire labels will help you to identify the wires quickly during installation.
