What is a blue wire in electrical?

Blue and Yellow Electrical Wires These wires carry power but aren’t used in typical outlet wiring. … Yellow wires are used as switch legs to ceiling fans, structural lights, and outlets paired with light switches, while blue wires are usually used as travelers for three-or-four-way switches.

Is a hot wire positive or negative?

Is blue wire live or neutral?

The blue wire is known as the neutral wire and its job is to take electricity away from an appliance. The brown cable – known as the live wire – actually delivers electricity to your appliance. Together, these two wires form a complete electric circuit.

Is the writing on a wire positive or negative?
