What is the purpose of a ground rod in a grounding system?

The purpose of a ground rod in a grounding system is to provide a direct physical connection to the earth for safety. When a ground rod is installed, it creates a low-resistance path that helps to safely dissipate any excess electrical energy, such as that caused by faults or surges, directly into the ground. This connection minimizes the risk of electric shock and protects equipment from damage by stabilizing the voltage levels within an electrical system.

A properly installed ground rod is crucial for ensuring that the grounding system effectively fulfills its role in protecting people, property, and equipment from potential electrical hazards. By grounding electrical systems, the ground rod helps to prevent dangerous voltage buildup and provides a means for current to safely flow to the earth, thereby enhancing overall electrical safety.
