What is the acceptable method for splicing a short wire to a grounding electrode conductor?

The correct method for splicing a short wire to a grounding electrode conductor is through the use of listed crimp-on splice connectors. This method is preferred because it provides a reliable mechanical connection while maintaining the integrity of the grounding system. Crimp-on connectors are designed to ensure a secure and low-resistance connection, which is essential for grounding applications where safety is paramount.

Using listed crimp-on splice connectors also means that the splice complies with relevant standards and electrical codes, ensuring that it has been tested for safety and performance. Proper use of these connectors involves selecting the correct size for the wire gauge and following the manufacturer’s instructions for crimping, which is crucial for achieving a strong joint.

While exothermic welding and listed split-bolts are also recognized methods for creating electrical connections, they might not be as suitable or convenient for splicing short wire lengths to grounding electrode conductors in all situations. Each method has specific applications, but listed crimp-on splice connectors are specifically designed to meet the requirements for grounding connections, making them the appropriate choice in this context.
