That look like a 1/3 hp motor, which is a 120 volt motor you got 6 wires on that motor three is for fan speed and they are black for high, blue for med.and red for low. If all that is correct, the diagram below would be the complete connection diagram. Canopy Mounted Control Connect the three grounding wires (green, green/yellow stripe, or bare copper) coming from the ceiling fan-rated electrical box, the downrod attached to your fan… Suggested Electric Fan Wiring Diagrams PAGE 1 These diagrams show the use of relays, ON/OFF sensors, ON/OFF switches and ON/OFF fan controllers. A remote-controlled ceiling fan bypasses one of the wall switches and allows for remote access to the ceiling fan's workings. A half inch opening is provided for the cable to enter into the junction box. Now find the red wire that is connected to the motor of the electric fan. Choose a spot along the electric fan's power cord for the toggle switch, and cut one of the power cord wires with wire cutters. The red from the switch goes to the red of the fan. Connect the black, white and ground wires from your 12/2 wire to the corresponding wires in the box using wire nuts. 3 wire is for fan speed , pick one, black or red , one is for high speed and one is low and then tape off unused wire on fan.hope that helps, if not i will try to explain better. Cut another piece of the 10-gauge wire long enough to go to the fan. The typical 120volt exhaust fan has a green ground wire, white neutral wire, and black power wire. Fan: Black wire is for the fan. There should be a white, copper or green, and black wire coming out of the ceiling's electrical box. A 3-wire fan has power, ground, and a tachometric (“tach”) output, which provides a signal with frequency proportional to speed. Run a 10-gauge wire with the appropriate terminals from the negative or ground side of the fan … Hi guys, i need your help! There is a remote inside the inner working of the fan, which responds to a remote control. The switch (all wires are cut and stripped) has L= Black, 1= White, 2=White, 3= Blue The capacitor is a 10uF, 250v. The motor has: 1 white (twisted with White 110), 1 black (disconnected), 1 blue (twisted with 2 yellow), 1 red (disconnected), and 2 yellow (twisted together with the blue wire). Ok, so I've decided to go the electric fan route. Click for details. 6 Stretch the length of wire from the circuit box to the fan's location. In this way the electric fan motors are wired in parallel, causing the fan motors to spin at high speed. Reference Diagrams #7&8onpage 2 The Electric Fan Assembly is built using a High Output two speed motor. It also mentions using the gray and brown wire both switched to achieve the high speed. Step 4. Red wire is sometimes included and acts as a conductor to carry power to the light kit. The two connection motor would use a hot black wire and a common white wire. Green wire is for the ground.
