Can the interconnected metal structural frame of a building be used as a conductor to interconnect electrodes of the grounding electrode system?

Using the interconnected metal structural frame of a building as a conductor to interconnect electrodes of the grounding electrode system is permissible. This approach is based on the principle that the structural frame's metallic components can effectively serve as a common conductor, providing a reliable path for grounding.

Metallic structures are inherently conductive; therefore, when properly connected, they can enhance a building's grounding system by allowing for better control of stray voltages and providing an effective path for fault currents. This connection contributes to the overall safety and functionality of the grounding system.

Utilizing the building's metal frame ensures that the grounding system adheres to safety codes and standards. In many cases, local electrical codes support this practice, provided that the interconnected frame is adequately bonded and installed in accordance with regulations. Thus, the option confirming that this practice is acceptable is indeed aligned with proper grounding and bonding principles.
