Bonding in electrical connections refers to the process of electrically connecting two equipment pieces to ensure that they have the same electrical potential, which helps to eliminate any voltage difference that could pose a safety hazard. This connection improves the safety of electrical systems by reducing the risk of electrical shock and fire due to stray voltages.

By bonding equipment, it ensures that any fault current can flow safely back to the ground, providing a clear path for the electrical current and enhancing the operation of protective devices like circuit breakers. This practice is crucial in ensuring that all parts of an electrical system operate cohesively and safely.

The other options describe related concepts but do not accurately define bonding. Connecting equipment to ground pertains more to grounding, which is a separate process from bonding. Isolating equipment focuses on preventing faults rather than creating a safe electrical connection. Connecting ground wires relates to grounding practices but does not encompass the broader concept of bonding between pieces of equipment.
