Could someone explain to me about how live, earth and neutral wires work?
Certainly! Live, earth, and neutral wires are part of the electrical wiring system used in buildings and homes. Let's go through each one:
1. Live wire (also known as hot wire): The live wire carries the electrical current from the power source to the electrical devices/appliances in your house. It is usually colored black, brown, or red, depending on your country's electrical standards. The live wire is dangerous because it carries a high voltage, so it should always be treated with caution.
2. Earth wire (also known as grounding wire): The earth wire provides a safe path for electrical current to flow to the earth in the event of a fault or short circuit. It acts as a safety measure to prevent electric shocks. The earth wire is typically colored green or yellow-green and is connected to the metal casing of electrical devices and the ground.
3. Neutral wire: The neutral wire completes the electrical circuit and carries the current back to the power source, usually a transformer or a power station. It acts as a return path for the electrical current. The neutral wire is typically colored blue or white in some countries. Unlike the live wire, the neutral wire carries little to no voltage, making it safer to handle.
To identify which wire is which, you should refer to your country's electrical code and regulations, as wire color coding may vary. It's important to note that working with electrical wiring should be done by a qualified professional to ensure proper installation and to prevent any potential electrical hazards.
