As a domain expert in electrical engineering and safety, I've spent countless hours ensuring that electrical systems are installed and maintained correctly to prevent accidents. One of the most crucial aspects of electrical safety is proper grounding, which is achieved through the use of an earth wire.
In most residential and commercial electrical systems, the earth wire is a critical component for safety. It is designed to provide a safe path for electrical current in the event of a fault, such as a short circuit, thereby preventing electrical shocks and reducing the risk of fire.
The colour coding of electrical wires is standardized to ensure consistency and safety across installations. In many countries, including those following the International Electrotechnical Commission (IEC) standards, the earth wire is typically coloured green or yellow. This colour coding is essential for easy identification during installation, maintenance, and in case of emergencies.
The three core wiring system mentioned refers to the standard wiring used in electrical mains supply, which includes the live (also known as hot or phase), neutral, and earth wires. The live wire is usually brown and carries the electrical current from the supply to the device. The neutral wire, which is blue, completes the circuit by allowing the current to return to the supply after passing through the device.
It is important to note that while green or yellow is the standard for earth wires, there can be variations based on local regulations or specific installation requirements. For instance, in some older installations or in certain regions, you might find earth wires in other colours such as green with yellow stripes or even bare (uninsulated). However, these are less common and are being phased out in favour of the standard green or yellow to enhance safety and recognition.
Moreover, the use of the correct colour for the earth wire is not just a matter of aesthetics; it is a safety measure that helps prevent confusion and potential mistakes during electrical work. This is particularly important in environments where multiple wires of different colours are present, and the quick and accurate identification of the earth wire can be the difference between a safe and an unsafe situation.
In summary, the earth wire is a vital safety component in electrical systems, and its standard colour is green or yellow. It is essential for all those working with electricity to be familiar with these colour codes to ensure the safety of both themselves and others.

The mains supply is delivered to houses using a three core wiring called the live neutral and the earth . The live wire is brown in colour and brings in the current. the neutral coloured Blue is the return wire . The earth is coloured green or yellow.
