What is the purpose of a grounding electrode system?

The purpose of a grounding electrode system is to provide a low-resistance path for fault currents to dissipate. This is crucial for safety in electrical systems. When a fault occurs, such as a short circuit or a lightning strike, the grounding system allows the excess electrical energy to safely flow into the ground. This minimizes the risk of electric shock to individuals and reduces the potential for damage to electrical equipment and the electrical system itself.

The grounding system effectively keeps the voltage at safe levels, preventing dangerous conditions that could lead to fires or equipment failure. By ensuring that there is a direct path to ground, the grounding system enhances the stability and safety of the electrical installation, making it a fundamental component of any electrical service in buildings.
