Grounding plays a crucial role in electrical systems, particularly in terms of safety. When an electrical system is properly grounded, it provides a safe path for fault current to return to the ground in case of a fault, such as a short circuit or equipment malfunction. This minimizes the risk of electric shock to users, as it helps prevent dangerous voltage levels from accumulating on metal surfaces, appliances, or equipment that humans may come into contact with. By directing excess current safely into the ground, grounding effectively limits the potential for serious electrical hazards.

In addition to enhancing safety, grounding can also play a role in equipment performance and stability. However, the primary focus and most vital benefit of a grounding system relate to reducing shock risk, making it essential for both residential and commercial electrical installations.
