Why is grounding necessary for electrical installations?

Grounding is essential for electrical installations because it provides a safe path for fault current. In the event of an electrical fault, such as a short circuit, the grounded system allows the excess current to flow safely into the earth. This reduces the risk of electric shock to individuals and minimizes damage to electrical equipment. By directing fault current away from people and structures, grounding helps ensure the safety of both the electrical system and those who may come into contact with it.

Improper grounding can lead to dangerous situations, such as fires or the failure of electrical devices, making it a critical safety measure in any electrical system. This function is fundamental to the overall design and operation of electrical installations, ensuring compliance with safety standards and protecting users.
