This guide provides step-by-step instructions for installing the GR58-40250 ground grid connector on ground rods.
Estimated time: 30m
Tools needed:
Wire brush, Hydraulic crimping tool, Knurling tool (optional)
Supplies needed:
Ground grid connector, Cable (4/0 AWG to 250 MCM), Mounting screws (if applicable)
- Prepare the cable
Clean the cable of all visible dirt using a rough cloth or brush and ensure a bright copper finish by wire brushing or a similar process.
- Insert the cable into the connector
Insert the prepared end of the cable into the ground grid connector, ensuring that it protrudes at least 3/4” beyond the connector.
- Crimp the connector
Use a hydraulic crimping tool with die 15G121R to make two crimps on the connector to secure the cable. Ensure that the crimp is tight and secure.
- Optional knurling
If using smooth ground rods, apply a knurling tool to the rod for better grip before installing the connector.
- Verify installation
Check that the connector is securely attached and that there are no loose connections. Ensure all tools are removed from the installation area.
