What is the primary purpose of equipotential bonding (grounding)?

The primary purpose of equipotential bonding, also known as grounding, is to equalize potential to ground for safety. This practice is essential in electrical systems as it ensures that all conductive parts that could potentially carry fault currents are at the same electrical potential. This reduces the risk of electric shock when someone comes into contact with grounded equipment or systems.

By bonding various parts of the system together and connecting them to a common grounding point, the risk of a significant difference in potential between equipment and the ground is minimized. This is particularly important in systems where people may come into contact with electrical installations, as it protects them from the hazards associated with electric shock.

When grounding is implemented effectively, it also helps in safely directing fault currents away from people and into the ground, reducing the possibility of injury or damage to electrical devices. Additionally, by having multiple components grounded to the same potential, it helps maintain the integrity and reliability of the electrical system as a whole.
