Which of the following best describes a bonding jumper?

A bonding jumper is best described as a short conductor that provides a low-resistance path. This is essential in grounding and bonding systems because the primary purpose of a bonding jumper is to create a connection that ensures electrical continuity between different metal parts or conductive systems. By providing this low-resistance pathway, the bonding jumper helps to facilitate the safe diversion of fault current, thereby preventing shock hazards and ensuring that all conductive parts are at the same electrical potential.

This characteristic of offering a low-resistance path is crucial for maintaining the effectiveness of the grounding system, as it minimizes voltage differences that might occur due to faults or other electrical disturbances. The use of bonding jumpers is important in applications where various equipment or structures need to be grounded together to mitigate the risks of electrical shock or fire hazards by ensuring that any stray currents are effectively routed away.
