Are grounding electrode conductors generally required to be installed without a splice or joint?

Grounding electrode conductors are indeed required to be installed as a continuous conductor without any splices or joints. This requirement is in place to ensure reliability and effectiveness in the grounding system. A continuous conductor helps maintain a low-resistance path for fault currents to ground, which is essential for the safety of the electrical installation and for the protection of equipment and personnel.

When splices or joints are introduced, they can become points of resistance, which may affect the grounding system’s performance. Additionally, these connections can be prone to corrosion or mechanical failure over time, leading to potential safety hazards. Various electrical codes emphasize the importance of maintaining uninterrupted grounding paths to ensure effective fault clearing and reduce the risk of electric shock or fire.

By implementing continuous grounding electrode conductors, the system provides a more stable and reliable foundational grounding, fulfilling the safety requirements outlined in electrical installation standards.
