What is a supply-side bonding jumper?

A supply-side bonding jumper is indeed a bond that ensures conductivity between metal parts. Its primary purpose is to connect together the grounded metal parts of an electrical system, ensuring that there is an effective conductive path that allows for the safe operation of the system. This is particularly important for maintaining the integrity of the grounding system, reducing the risk of electric shock, and ensuring that overcurrent protection devices function properly in the event of a fault.

This jumper typically connects the supply side of the service equipment to the grounding electrode, thereby allowing any fault current to be effectively conducted back to ground. By ensuring that different metal structures or equipment connected to the electrical system are at the same potential, the supply-side bonding jumper helps to mitigate any potential electrical hazards.

While other options mention related components of electrical systems, they do not specifically define the unique function of the supply-side bonding jumper. For instance, a conductor for grounding purposes is broader and may not imply the specific bonding function. Similarly, a type of grounding electrode refers to a different aspect of grounding systems, and a neutral conduction path primarily refers to the return path of current in the system rather than the bonding function.
