Blackburn GG58H – Frequently Asked Questions
1) What size grounding conductor does the Blackburn GG58H ground rod clamp take?
It is built for 8 AWG solid conductor. If your grounding electrode conductor is a larger size, or stranded rather than solid, you need a different clamp in the Blackburn ground rod clamp range rather than this one.
2) Is the GG58H clamp copper, and can I use it on a copper-bonded ground rod with a copper conductor?
The conductor path on the GG58H is copper, so it pairs with copper grounding electrode conductor and copper-bonded rod without creating a dissimilar-metal connection at the rod. There is no insulation on the clamp; it is a bare mechanical grounding connector.
3) Is this a heavy duty ground rod clamp or a light acorn style clamp?
The GG58H is the heavy duty pattern ground rod clamp, not a light acorn. It is intended for the rod-to-grounding-electrode-conductor connection at a service or equipment ground and is a mechanical grounding device, so no exothermic welding or crimp tooling is involved.
4) What tool do I need to tighten the GG58H ground rod clamp?
It uses a hex head screw, so a socket or wrench does the job rather than a screwdriver. That is the usual choice for direct-burial rod connections where you want a solid torque on the conductor.
5) Is the Blackburn GG58H sold individually or in a box?
It is sold each, so order one clamp per rod-to-conductor connection. On a service with multiple driven rods, count one per rod plus any bonding taps you are making.
6) Where is the Blackburn GG58H clamp made?
Country of origin is India. That is the detail institutional and government buyers usually need for domestic-preference or procurement paperwork on electrical material.
