According to standards in use since the mid-1900s, a wire color code identifies the purpose of each wire in an electrical circuit the white wire is always neutral, and when the cable has only two conductors, as most 120-volt cables do, the hot wire is black. Electrical wire colors red white black. Don't be confused by the number of electrical wire colors you find—we've got just the guide to help you decipher their color coding from the black and white wires, while the red wire.
electrical wire colors red white black
Most electrical outlets require two conductors, not including the ground wire, which isn't really part of the circuit one of the conducting wires -- the neutral -- is white; that color is mandated by the national electrical code by convention, the other is usually black, but it could be red usually, though, you see a red wire only when the. So first, they made it into 64 pairs of two wires each (there were other advantages) and then using 6 colors and having a second color for the second wire (e.g. white & orange, white & blue, red & green) they could have a means of identifying each of the 64 pairs of wire.. What the color of an electrical wire means black electrical wires. this color of wire is used to transfer power to switches and outlets in all types of circuits. also, black wires are often used as switch legs in circuits, which is the connection linking a switch to the electrical load. consider all black wires to be live at all times. red.
