When is earthing required?

As it's a safety factor, earthing is essential and mandatory. It's an electrical connection between the exposed metallic parts of an electrical appliance or installation and the earth, regarded to have zero potential. Proper earthing provides an alternative and easy path for leakage or faulty current to flow. It ensures that any exposed conductive part of the appliance does not reach a dangerous level of potential or voltage that endangers the user's life. A proper earthing system should have least electrical resistance, good corrosion resistance and ability of dissipating high faulty current.


How does good grounding in your house affect electricity bills?
