Is it acceptable to assemble grounding jumpers with cables manufactured for welding?

Using cables manufactured for welding to assemble grounding jumpers is generally not acceptable because welding cables are designed for specific applications related to welding processes, which may not meet the safety and performance requirements necessary for grounding purposes in substations. Grounding jumpers need to adhere to stringent regulations and standards that ensure they can effectively handle fault currents without failure, thereby providing safety for both equipment and personnel.

Grounding cables are typically constructed to have specific insulation properties, flexibility, and conductivity characteristics suited for grounding purposes. If equipment is grounded improperly, it can lead to higher risks of electrical shock, equipment damage, or even fires.

While some might argue about the use of welding cables under certain conditions, such as in emergencies or if they are certified, the standard practice maintains that only cables specifically designed for grounding should be utilized to ensure complete safety and compliance with electrical codes and standards.
