Grounding primarily serves to protect against electrical shock by providing a safe pathway for electrical current to flow to the ground in the event of a fault. This is essential for the safety of people and property. When electrical systems are properly grounded, any stray currents that might otherwise become dangerous are redirected harmlessly into the earth, preventing the risk of electrical shock for anyone who might come into contact with the electrical installation.

Grounding also helps stabilize voltage levels and can aid in the protection of equipment by minimizing the chances of equipment receiving an unexpected surge of electricity. While overheating, circuit damage, and power interruptions are important considerations in electrical installations, grounding specifically addresses the safety concerns related to electrical shock for both individuals and pets, ensuring that any potential faults do not pose a significant risk of injury.
