What is the main reason for grounding electrical equipment and circuits?

Grounding electrical equipment and circuits primarily serves the critical function of protecting personnel from electric shock. When electrical systems are properly grounded, any fault currents that may occur due to equipment failure, insulation breakdown, or accidental contact with live wires can be directed safely to the ground. This minimizes the risk of electrical shock to individuals who may be handling or nearby the equipment, ensuring their safety during operation and maintenance.

In addition to safety, grounding also helps in stabilizing voltage levels in the electrical system, which can contribute to the overall reliability and functionality of the equipment. However, the foremost objective remains the protection of human life from the hazards associated with electrical faults. The effectiveness of grounding makes it an essential practice in any facility that utilizes electrical machinery and equipment.
