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. One of the hot wires attaches to a brass terminal on one side of the outlet and the other attaches to a brass terminal on the other side.

Red black and white wires. Also black wires are often used as switch legs in circuits which is the connection linking a switch to the electrical load. Before reading this information it is important to note that there are different wiring color codes. Red or orange can also be used as a second switched power wire in a 120 volt application. The colors regulated by the national electrical code in the united states are standardized for safety. If it doesnt work switch the lower wires. In that wiring scheme assume the black and re marked white wires are live.
What each ceiling fan wire means wiring color codes. The ground wire also connects to the switch but the white wire gets spliced to the circuit neutral wire and bypasses the switch. 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 red or striped wire. Like black wires they can also be used in some types of switch legs. A ceiling fan usually consists of two main parts.
Black wires are always hot wires meaning that they carry electricity. The white wires on the fan go to the bundle of white wires. The cable has a black wire which connects directly to the circuit and a red wire which connects to the switch. Electricians often use black red or blue wires to deliver electricity to a circuit from the main panel. In 220 volt circuits red wires are the secondary live wires. When measured with respect to the white neutral wire the red wire carries the same 120 volt current that the black one carries making the voltage across these two hot wires 240 volts.
A three way switch is different. This is a typical wiring setup for a 3 way light switch with black white red and ground wires. 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 black wire goes to the bundle of black wires. When installing a. The fan and a lighting assembly.
Consider all black wires to be live at all times. Red black white blue. The white wire is the neutral and all other colors are hot. Then the red wire in your box goes to the non white wire on your ceiling fan which is often blue. 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. They may use other colors for.
