What is the required connecting method for grounding electrode conductors?

• A. Several short segments joined by reversible compression or exothermic welding
• B. A single continuous length unless spliced with irreversible compression or exothermic welding
• C. Multiple short lengths joined by mechanical connections
• D. Splicing with soldered joints

Answer: (B)

Grounding electrode conductors are meant to provide a continuous, low-impedance path from the grounding electrode to the service equipment. When you must join pieces, the splice must be permanent and reliable so the ground path doesn’t loosen or corrode over time. Therefore the preferred setup is a single continuous length. If a splice is necessary due to routing, it must be made with an irreversible method such as an irreversible compression connector or an exothermic weld. These methods create a permanent, solid connection that won’t loosen under load, vibration, or corrosion, which is crucial for maintaining a dependable ground. Reversible compression, soldered joints, or purely mechanical connections don’t meet that durability standard for grounding paths, which is why the valid approach is a single continuous length unless spliced with irreversible compression or exothermic welding.
