Question about Optics
I HAVING TROUBLE WITH THE WIRING. DO YOU HAVE SCHEMATICS
Usually when you say 4 wire, the correct electrical definition is 12/3 or 14/3 with a ground, depending on the amperage capacity of the circuit that the fixture is powered by. The bare copper wire is case ground which goes to the metal body of the fan and is combined with all the other bare copper grounds in the switch box on the wall. The white wire is the neutral or return. it is connected to the white wire in the fan at the ceiling box and combined with all the other white wores in the switch box. The black wire is usually the light power which is then connected to the appropriate connection (labeled) on the switch in the switch box on the wall. The red wire is the power for the fan (which is also labeled) in the switchbox on the wall. Sometimes the wiring at the ceiling box is not 4 conductors especially in older buildings, then the fan and the light power wires are combined at the ceiling box with the existing black wire. Then the ceiling fan and light goes on and off at the wall switch together and the speeds are controlled by a pull chain at the fan. The kight can be shut off with a pull chain also so that the fan is on onl.y.
