What is one of the approved methods for making a tap connection from a common grounding electrode conductor?

The approved method for making a tap connection from a common grounding electrode conductor involves using a copper busbar that meets specific dimensions: not less than ¼ inch thick and 2 inches wide. This method is favored because the busbar provides a robust and reliable connection point that maintains the integrity and performance of the grounding system.

A busbar of this size ensures good conductivity and minimizes resistance, which is critical in grounding applications to effectively dissipate electrical faults. Additionally, using such a busbar can help distribute current over a larger area, reducing the likelihood of heat buildup and potential failure at the connection point.

While solder joints, crimp connectors, and split bolt connectors may have their own specific uses in electrical work, they may not meet the same level of reliability or the specific code requirements for grounding electrode connections as stipulated in electrical standards.
