What is the main purpose of bonding in an electrical system?

The main purpose of bonding in an electrical system is to reduce impedance between different metallic components. Bonding connects these metallic parts together, which creates a low-resistance path for electrical currents. This is crucial in preventing stray voltages and ensuring that in the event of a fault, the electrical current has a safe route to ground. By achieving low impedance through bonding, the system can effectively handle fault currents, reduce the risk of electric shock, and help maintain system stability.

In contrast, options related to aesthetics or enhancing electrical performance do not address the primary safety function of bonding. While it may indirectly contribute to overall system performance by ensuring reliable operation, the core purpose revolves around safety and minimizing risks associated with electrical faults.
