What is earth wire and what is its use?
The metal wire that is removed from the electrical equipment and connected to the ground and transmits the leakage of electricity to it is called Earth wire. This branch of the wire protects users from the risk of electrocution and prevents electric current from entering and passing through their body, which is associated with damage and electrocution.
Why is it important to use earth wire?
Wires connected to electrical devices and appliances get rotted and torn for various reasons and cause problems. This may happen as a result of prolonging the life of the device and the decay of the cover of its wires, or it may happen when the device is transported and moved while it collides with the environment or surrounding objects. It increases the uncovered part of the wire and can be dangerous for users. The presence of a yellow-green earth wire in the device that transfers the excess current to the ground eliminates this risk. The resistance of this wire is equal to zero, and due to the strong current passing through it to the ground, it causes the ampere to rise and the fuse to jump, cutting off the current in the circuit and providing the necessary safety during work. In this way, the occurrence of fire in the equipment Electric shock is prevented. The presence of the third hole in the outlet means the presence of an earth wire in it, and it is a sign of additional electricity transmission to the ground and greater safety.
Application of earth wire:
Prevention of electric shock
Prevention of fire and accidents leading to injury and death
Conductivity of the ground and the passage of electric current
Fixing the voltage level and preventing circuit overload and current leakage
> Protection against excess electric charge such as lightning or strong current introduced into the circuit
