What does bonding refer to in electrical systems?

Bonding in electrical systems pertains to the process of creating a continuous electrical connection between multiple conductive parts. This is essential for ensuring that there is a low-resistance path for electrical currents to flow, which serves a vital safety function. By bonding conductors and equipment, the risk of electrical shock and equipment damage is minimized, as it helps in equalizing electrical potential and allows for fault currents to find their way back to the ground safely.

The concept of bonding is particularly important in preventing any build-up of static electricity and reducing the risk of electrical hazards. When conductors are properly bonded, it ensures that all connected parts maintain the same electrical potential, which is crucial in the event of a fault condition.

In contrast, the other options address different aspects of electrical systems that do not define bonding. Insulating wires is about preventing unwanted current flow, connecting circuits pertains more to increasing the system's performance rather than safety, and uniformly distributing energy relates to load balancing, which is a separate function from bonding.
