Key Stage 4

Meaning

This diagram shows the live wire in the 3-Core cable.

The live wire is one of the three wires in 3-Core and a plug that has a brown plastic covering and is held at a potential of 230 Volts.

About Live Wires

The live wire is covered in brown plastic insulator.
The live wire is the most dangerous wire in 3-Core and plugs.
The live wire is connected to a fuse in the plug so that if too much current goes through it into an appliance the fuse will break and stop the current.
