Earthing Importance

Earthing is the first step towards electrical safety. The body of electrical equipment’s, appliances etc. is to be connected to earth for safe discharge of electric current to the earth, in the event of any leakage , fault etc. The earth is considered to be zero potential. Earthing is done to provide safety to user from electric shock.
