The white red and black wires in an electric ac motor supply power to the motor itself and determine which of the speed coils turn on when electricity is supplied. The ground wire also connects to the switch but the white wire gets spliced to the circuit neutral wire and bypasses the switch.

Red white black wires. Your house is set up for a fan with a light on itblack wire the fan you purchased seems to have no lightno black wire wire your fan red red white white green ground and cap the black wire. Try the switch after you wire it up. The cable has a black wire which connects directly to the circuit and a red wire which connects to the switch. White wires with black or red tape. The different colors of electrical wires indicate the function of the wire with black and red indicating the wires carry electric current white usually indicating neutral charge and green indicating the wire is grounded. If the fan doesnt come on first make sure you have power then wire the red to the black and cap the red.
The colors regulated by the national electrical code in the united states are standardized for safety. They may use other colors for. Typically this is indicated with a band of black or red electrical tape but other colors may be used wrapped around the wires insulation. The black wire goes to the bundle of black wires. However a black wire can never be used as a neutral or ground wire or for any purpose other than to carry a live electrical load. That color is mandated by the national electrical code.
When you see a red wire in a light switch box it can mean two things. The white wire is the neutral and all other colors are hot. By convention the other is usually black but it could be red. Hot when a white wire is augmented with a red or black color marking this often indicates that it is being used as a hot wire rather than a neutral wire. It could be there is or once was a three way switch in play. Regardless of output setting power will be applied to this wire.
Or it could be the red wire is the wire going to the fixture and the black wires are the live wires. In almost every motor design the white wire will be the neutral. White wires augmented with red or black tape or markings are used as hot. Electricians often use black red or blue wires to deliver electricity to a circuit from the main panel. Usually though you see a red wire only when the outlet is a 240 volt one or when its controlled by a switch. Well cover the easier scenario first.
Then the red wire in your box goes to the non white wire on your ceiling fan which is often blue. One of the conducting wires the neutral is white. If you only have black wires in your box connect both the non white wires from the fan to the black wires in the box. The white wires on the fan go to the bundle of white wires. The standard way to power a split tab outlet is to run a three conductor cable to a wall switch.
