The Line (brown) wire is the dangerous conductor because it remains at a high potential relative to the earth or ground, meaning touching it can result in electrocution. The Neutral (blue) wire is typically maintained near earth potential at the supply point, although it still carries current under normal operation. It is the negative or "return" wire which will connect to the white wire.
As for its function, it is to transfer electricity away from the appliance, as opposed to the brown wire. The blue wire connects to the neutral terminal which is usually on the left of the plug. The combination of these two wires creates a circuit.

The wire plug color code serves as a critical guide for safely wiring and repairing electrical plugs in residential, commercial, or international settings. Knowing which wire goes where helps prevent shorts, shocks, or equipment damage. Simplify electrical projects with a guide to wiring color codes for brown, blue, and green.
The three-pin plug typically consists of three wires: live (brown), neutral (blue), and earth (green and yellow). Each wire has a specific role in ensuring the safety and proper functioning of the electrical system. Understanding what wire colors mean will help you complete electrical projects safely.
Follow this guide to distinguishing blue and brown wires. There are various types of plugs which use blue, brown, yellow and green wires. These include standard three-pin plugs, two-pin plugs, four-pin plugs, and USB plugs.
4). Wiring Brown/Blue Connections The brown wire runs to the black wire on your property. Both lines are live and energized in an active circuit.
This makes them highly dangerous. The blue wire runs to the white wire. Both lines are neutral and negative.
They carry the current back to the source. How to Identify and Connect Plug Socket Wiring Colours Connecting plug sockets may seem like a complex task, but with some basic knowledge of wiring colours, it becomes much simpler. In the UK, there are three main wiring colours used for plug sockets: brown (live), blue (neutral), and green/yellow (earth).
Learn about the wiring colours for a 3 pin plug and their corresponding functions. Ensure safety and proper installation with this guide.
