There is usually a schematic or table on the inside of your circuit breaker panel that will tell you what part of the house each circuit controls. If you don’t know which switch controls your fan, turn on all the lights in your house. Once the lights are on, flip each switch until you switch off the power in the part of the house where the fan is located. That switch most likely controls the power to your fan.
For instance, fans that have lights will require a slightly different installation process than fans without them.
The black and blue wires are called hot wires because they hold electrical current. If you have a blue and black wire hanging out from your ceiling, you should also have 2 switches on your wall.
Make sure that you tighten the screws well or the fan will wobble when you turn it on.
If you can’t hang your fan, have someone hold it in place for you as you install it.
If the copper ends of your wires are already exposed, you can skip this step.
Connecting the neutral wires will complete the circuit in your fan. You may want to wear thick gloves to prevent yourself from getting cut on the copper.
The 2 green wires are your grounded wires and prevent damage to your fan from power surges. [12] X Research source
If your fan doesn’t have lights, you’ll only have to connect the black wires.
Screw in all the screws or your fan won’t be stable.
