What does bonding in electrical systems ensure?

Bonding in electrical systems primarily ensures a secure return path to ground. This means that bonding helps to minimize voltage differences that could potentially exist between different parts of an electrical system. By connecting various conductive parts together, bonding creates a path for fault currents to flow safely to the ground, which protects both equipment and people from electrical shock.

While a continuous connection between conductors is important in electrical systems, it is not the main purpose of bonding. The primary goal of bonding is to provide safety through a reliable and low-resistance path to ground, thus ensuring that in case of a fault, the electrical current has a safe route to dissipate, reducing the risk of electric shock and fire hazards. This grounding aspect significantly contributes to overall circuit safety and system stability.
