Most of us have experienced mild shocks when coming into contact with certain appliances. In order to avoid life-threatening accidents, it is always advisable to earth the building properly to prevent serious mishaps associated with these shocks.
Earthing prevents electrical damage to devices by allowing current to leak. An earthing system sends charges directly to the ground through low resistance wires in order to generate an immediate discharge of electrical energy. It is done to prevent life-threatening, hazardous shocks from electrical appliances due to the leakage of currents. In short, it is a technique of grounding all the unnecessary current.
Generally copper strips are used for earthing since these strips are corrosion resistant, durable and offer better voltage transient protection. Strip earthing allows easy flow of current from faulty electrical appliances to the ground. Moreover, the metal strips are covered in an insulating material that protects them from soil corrosion. Therefore, strip earthing should be used to ground all electrical appliances for safety reasons.
The process of transmitting current from the electrical appliances to the ground through a metallic strip of low resistance is known as strip earthing. Hot-dipped galvanized strips are used for earth stripping and have a diameter of 6mm. These strips are laid horizontally in trenches with a depth of 0.5m.

While there are many ways to ground leakage currents, strip earthing is the most common and appropriate method. Therefore, is it safe to claim that it is the most valuable and effective way of preventing damages caused by current leakage.
