How does live and neutral work?
The plug contains three wires – the live, neutral and earth wires. In a plug, the live wire (brown) and the neutral wire (blue) are the two wires that form the complete circuit with a household appliance. The earth wire (green and yellow) does not normally form part of the circuit and is included as a safety wire.
Does it matter if hot and neutral are reversed?
This happens when the hot and neutral wires get flipped around at an outlet, or upstream from an outlet. Reversed polarity creates a potential shock hazard, but it’s usually an easy repair.
What does blue and brown wires mean?
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.
