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

What does the neutral wire do UK?

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