Understanding Electrical Cables and Wires Never overload a wire -- for instance, never wire a 20-amp circuit with 14-gauge wire. Wires coated with insulation that is black, red, or another color are hot wires, carrying power from the service panel to the electrical device. White wires are neutral, meaning they carry power back to the service panel. Green or bare wires are ground wires.

In house wiring, why is the black wire hot? never assume one color wire is the hot wire you never know what someone wired a item or a circuit up with maybe they only had green wire on their truck. I don't care if the wire is red, white, purple, blue, green or black i always to test to see what wires are my hot wires and what wires are line voltage.es, generally black is the code for the hot wire. White is generally neutral, and green is ground. There are weird exceptions, so don't assume anything about anything. White and green are not the same, by design.

Electrical Wire Color Coding Red Wires. Red wires are also used for hot wires, switch legs (like to a ceiling fan), and are the second hot wire in 220-volt installations. Another useful application is the interconnect wire between two hardwired smoke detectors. Blue and Yellow Wires. Blue and yellow wires are used as hot wires.These wires are usually pulled in conduit. The blue wires are generally used for travelers in three-way and four-way switch applications. They also are used as switch legs to things like lights and fans. Yellow wires are generally used for switch legs.ut looking deeper, the color of the wires inside of the sheath, like in type NM cable, will reveal that different color wires serve different purposes. Black Wires. Black wires are always used for hot wires. These wires may feed a switch or outlet and are often used as switch legs.

Electrical Wire Color Coding As you can plainly see, the color of the wire coating is used to inform everyone of the wire's use. If you don't have the right color wire for your purpose, you can still make the wire's use clear. A good example is using black wire in place of a red wire. By simply wrapping red electrical tape on each end of the pulled black wire, it is easily identified as a red wire.
