What is a requirement for grounding electrode conductors when a splice is not permitted?

The requirement for grounding electrode conductors to be of a single continuous length is rooted in ensuring reliability and safety in grounding systems. A continuous conductor minimizes potential points of failure, which could occur at splices or connections. Joints and splices can introduce resistance or even points of failure in electrical systems, especially if not executed properly. By using a single continuous length of conductor, the integrity of the grounding pathway is upheld, ensuring effective grounding and bonding.

In grounding systems, maintaining low resistance is vital for the safety of electrical installations, including the protection of both equipment and personnel. Grounding electrode conductors that are not spliced retain their designed electrical characteristics and are less susceptible to issues related to corrosion or mechanical failure that may arise in spliced connections.

This requirement underscores the importance of a straightforward and effective grounding path, contributing to the overall safety and performance of electrical systems.
