What Happens If Your House Is Not Grounded? The greatest risk of a house that isn’t grounded is electric shock and fires when short circuits occur or when there is a power surge from overloading. When grounding is not present, there is no alternative pathway for excess electricity to flow to the ground (The least resistant part). Thus, electricity will be forced to go through your electrical appliances or a human being causing electric shocks. Also, using a surge protector on an ...
Is your house properly grounded?
Having your house grounded is an essential safety measure that you need to keep in mind.
