What connection method is recognized for providing a reliable bond between grounding electrode conductors?

The recognized method for providing a reliable bond between grounding electrode conductors is exothermic welding. This process creates a molecular bond through a chemical reaction involving metal powders that generate intense heat, resulting in a strong and durable connection. The bond produced is not only reliable but also resistant to corrosion and mechanical stress, making it particularly suitable for grounding applications where long-term performance and integrity are essential.

Exothermic welding is favored in grounding systems because it ensures a low-resistance connection that can withstand environmental conditions and electrical demands, thus maintaining the effectiveness of the grounding system over time. This method is especially important in critical applications where safety and system reliability are paramount.
