Grounding is the smart way to protect humans and other resources at home, office or any place. Grounding will protect against heavy loads. There may be situation where suddenly the load of electricity is high, the earth accepts the unwanted high voltage and protect the place and lives.
Grounding helps to “direct” the electricity throughout the electrical system. It defines the clear path.
It also stabilizes levels of voltage. It transfers equal amount of electricity to each and every portion of the electrical system.
