Red White And Black Electrical Wires

White wires augmented with red or black tape or markings are used as hot.

Red white and black electrical wires. 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. In addition red wires are used to connect hardwired smoke detectors to the home s power system. Like black wires they can also be used in some types of switch legs.
