What is the main purpose of grounding in electrical systems?

The main purpose of grounding in electrical systems is to provide a safe path for stray currents. Grounding establishes a reference point for the electrical system and helps protect both equipment and individuals from electrical faults. In the event of a fault, such as a short circuit or equipment failure, grounding directs excess current safely into the earth, reducing the risk of electric shock and minimizing damage to equipment.

This safety mechanism is crucial in preventing hazardous situations, such as electrical fires or shocks that can occur if stray currents are allowed to flow freely through unintended pathways. Grounding also stabilizes voltage levels in the electrical system, but its primary function is centered on safety and the management of fault conditions, making it essential for protecting both human life and sensitive electronic equipment.
