The earth wire is one of the three wires in 3-Core and a plug that has a yellow and green striped plastic covering and is held at a potential of 0 Volts.
About Earth Wires
- The earth wire is covered in yellow and green stripped plastic insulator.
- The earth wire improves the safety of electrical appliances.
- The earth wire is connected to the metal case of an electrical appliance so that if the live wire breaks and touches the metal the current will go down the earth wire and cause the fuse to break.
