Other Colored Wires These are the most common colors used in electrical wiring. Blue and yellow wires are sometimes used as hot wires and as travelers, green wires (and bare copper wires) are ground wires, and white and gray wires are neutral.
Where does the blue wire go on a light switch?
The faceplate of a single, one-way switch has two terminals: “L1” is the terminal to which the neutral core wire is attached – the blue wire (traditionally black, before the change). “COM” or “Common” is the terminal to which the live core wire is attached – this is the brown wire (formerly red).

A blue wire may be connected to a negative terminal of the power source. There is something but. A blue wire should be connected to a positive terminal and a black wire should be connected to a negative terminal in a two wire system.
What is blue electrical wire used for?
Blue wires are mostly used as travelers in three or four-way switches, for example, switches at the bottom and top of a staircase controlling the same light (three-way). When white wires are covered with black or red tape, they are hot wires. Green wires are used to ground electrical circuits.
What is the blue wire in headphones?

Can a white wire be hot?
White Wire Labeled as Hot Sometimes a white wire is used as a hot wire—not a neutral—in a switch leg, or switch loop, between a switch and a light fixture. The power is fed up to the light fixture, so there is a hot, neutral, and ground wire already there.

Black, Red, and Blue are used for hot wires while White is used as the neutral wire. Brown, Orange and Yellow are used as hot wires, while gray is used as the neutral wire.
How can you tell if a wire is positive or negative?
If you have a wire where both sides are the same color, which is typically copper, the strand that has a grooved texture is the negative wire. Run your fingers along the wire to determine which side has the ribbing. Feel the other wire which is smooth. This is your positive wire.
