Answer Details
Electrical appliances at home are normally earthed so that a person touching the appliances is safe from electric shock. When an appliance is not earthed and there is a fault, it can become live and carry an electric current. If a person touches the live appliance, the current can flow through their body to the earth, causing electric shock. However, when an appliance is earthed, any fault current flows to the earth instead of flowing through the body of the person touching the appliance, making it safer.
