What are the blue and brown wires?

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.

Which wire is hot if both are black?

Here’s a rundown of electrical wires: The black wire is the “hot” wire, which carries the electricity from the breaker panel into the switch or light source. The white wire is the “neutral” wire, which takes any unused electricity and current and sends them back to the breaker panel.

Which wire is positive when both are black?

If the multi-colored wire is black and red, the black wire is the negative wire, while the red one is positive. If both wires are black but one has a white stripe, the striped wire is negative, while the plain black wire is positive. Look in the owner manual to determine which wires are negative in a car.
