A bonding conductor is a type of electrical conductor used to establish electrical continuity between metal components of an electrical system. Its primary purpose is to create a low-resistance path for electrical currents to flow in order to prevent the buildup of static electricity, reduce the risk of electric shock, and minimize the potential for damage due to lightning strikes or electrical faults.

In electrical systems, bonding conductors typically connect metallic components such as electrical enclosures, conduit systems, grounding electrodes, and metal structures to ensure that they are at the same electrical potential. This helps to prevent differences in potential that could lead to dangerous electrical shocks or equipment damage.

Bonding conductors are often made of copper or other highly conductive materials and are sized appropriately based on the specific requirements of the electrical system and relevant electrical codes and standards. They play a critical role in ensuring the safety and proper functioning of electrical installations.
