What is the purpose of electrical appliances connecting to the ground?

The primary purpose of electrical appliances connecting to the ground is to prevent people from being electrified. Grounding provides a safe pathway for electric current to flow back to the ground in the event of a fault, such as a short circuit or a failure in insulation. This protects users from electrical shocks, which can be dangerous or even fatal.

When an electrical fault occurs, if the appliance is properly grounded, the excess current is diverted away from the user and into the ground, minimizing the risk of harm. This safety mechanism is crucial for all electrical devices, especially in environments where water or moisture is present, increasing the risk of electric shock. By enabling a secure path for electrical faults, grounding is a fundamental aspect of electrical safety design in appliances and equipment.
