What does bonding primarily help to control?

Bonding primarily helps to control voltage after grounds are applied. In electrical systems, bonding involves connecting various conductive parts to ensure that they have the same electrical potential. This is crucial for mitigating the risk of electrical shock and ensuring the safety of both personnel and equipment. When a fault occurs, such as when a ground is applied, proper bonding can help stabilize the voltage levels across the system by providing a low-resistance path for fault currents, allowing protective devices to operate effectively.

By facilitating the equalization of potentials, bonding minimizes the risk of dangerous voltage differences that can arise in the event of a fault. This is essential in maintaining safety standards and protecting equipment from damage in case of electrical failures. Thus, the correct answer reflects the critical role bonding plays in voltage control following grounding situations.
