Earth is considered at zero resistance and hence it is the best way to supply an alternate way for the fault currents/ excess currents to easily flow to the earth and has become a universal standard of safety for all electrical equipment. Although Chemical earthing have been the most successful and easiest way to provide this alternate root to the fault current but there are certain things which need to be kept in mind:

• Soil resistivity
• Soil Condition
• Moisture
• Dissolved Salts
• Physical composition
• Location of earth pit
• Area Available
