You’re going to have to make Pigtails

In electrical work, A pigtail is a collection of seamed wires along with a short length of yarn. The pigtail allows you to connect all the cables to a single terminal. The key to making an effect is to twist the wires together clockwise-not anti-clockwise-before screwing the Lid. In this way, the wires to the right of the plug make the connection tighter when Screwed.


Converting two switches in the same box to a switch

Disconnect the two black wires from both switches. If you don’t know what power to each switch, turn on again and test the wires by connecting each to the ground with your voltage checker. The live circuit wires will give you a reading and the others Won’t. Turn off the circuit breaker when you know which is Which.

Make a pigtail with two live wires and a short length of the same caliber black Wire. Connect the short cable to the top terminal of the switch you want to Use. And Do the same with the other two wires and connect them to the lower terminal of the Switch.

Unscrew the cover of the two white wires that serve the switch that is no longer in use, add a short length of white wire of the same caliber and screw the cover back to make a Pigtail.

Connect the white wires in the same way, then repeat with the ground wires. By splicing the ground wires, you don’t have to cover them, but it’s still a good idea to do it because the lid helps keep them together. Mount the fan and turn it on and move it to the switch compartment.

Connect the black fan wire to the lower terminal of the switch and the live circuit cable to the upper Terminal. Gather the white wires and cover them. Twist the ground wires together then connect them to the green ground screw on the switch.
