What is the function of a grounding electrode rod or conductor outside a building?

Explanation:
A grounding electrode rod or conductor outside a building is part of the grounding system that ties the electrical system to the earth. Its main purpose is to provide a low-impedance path for fault currents and surge energy so they can dissipate into the ground, which helps keep equipment and metal parts at earth potential and allows overcurrent protective devices to trip quickly to reduce shock risk. This is not the route for normal current to the utility, nor is it intended to connect lighting circuits or anchor the building directly to the foundation.
