What is a requirement for the installation of a grounding electrode conductor?

The requirement for the installation of a grounding electrode conductor states that it must be continuous without splices or joints, except at approved connections. This is crucial because any interruption in the grounding system can compromise its effectiveness. A continuous conductor ensures a reliable path for fault currents to flow safely into the ground, minimizing the risk of electric shock and equipment damage.

Maintaining continuity helps in reducing resistance and improving the overall performance of the grounding system. Approved connections might include certain types of splicing methods that have been recognized by the code, but these should be used sparingly and with consideration of their long-term reliability. Therefore, ensuring that the conductor is uninterrupted under normal circumstances is vital for the safety and functionality of electrical installations.
