Which connection method is typically used to bond metal parts in electric systems?

The use of a bonding jumper is a typical method for connecting and bonding metal parts in electrical systems. This method involves a conductive connection that ensures all parts share the same electrical potential, which is crucial for safety and performance. Bonding jumpers are specifically designed to reduce the risk of electrical shock and prevent electrical arcing by maintaining a low-resistance path between different metal components. This is particularly important in various applications, such as in grounding systems where ensuring that all metal parts are at the same potential helps to prevent differences in voltage that could be dangerous.

While other methods such as welding, screwing, and using clips can create physical connections between metal parts, they may not always ensure the same level of electrical bonding as a dedicated bonding jumper does. Welding can create a strong mechanical bond but may not be practical for all components or configurations. Screwing and using clips can offer physical attachment but may not ensure the necessary electrical conductivity required for effective bonding in certain situations. Thus, bonding jumpers are specifically utilized for their effectiveness in electrical bonding within systems.
