Generally, the grounding electrode conductor must be installed how?

The grounding electrode conductor must be installed in one continuous length to ensure its effectiveness in providing a low-resistance path to ground. This uninterrupted length minimizes resistance, helps avoid potential points of failure, and ensures reliable performance in the event of a fault condition.

Using a continuous conductor without splices enhances the grounding system's reliability since joints and splices can introduce resistance and points of potential failure. Moreover, if splices are needed, they may not be as secure or conductive as a solid piece due to factors like corrosion or inadequate connection techniques.

This installation practice complies with electrical codes that emphasize the importance of continuous grounding pathways for safety and system integrity. Therefore, the preference for a continuous length is rooted in the need for safety and functionality in grounding systems.
