Blackburn GH2TB – Frequently Asked Questions
1) What wire sizes does the Blackburn GH2TB ground clamp take?
The GH2TB is rated for #4 solid through 2/0 conductor. That range covers the usual grounding electrode conductors on residential and light commercial services, from #4 solid copper up to 2/0. Anything smaller than #4 or larger than 2/0 needs a different clamp.
2) Can I run two ground wires through one clamp instead of two separate clamps?
Yes. The GH2TB is a parallel double clamp, so it takes two conductors running parallel in a single body. That is what you want when you are bonding two grounding conductors at the same point instead of installing two separate clamps side by side.
3) Is the Blackburn GH2TB clamp body bronze or steel?
Bronze. The conductor material on the GH2TB is bronze, which is what you use for direct burial and damp locations where a plated steel clamp would corrode out. Bronze on copper conductor also avoids the dissimilar metal problem you get with aluminum bodies.
4) What is the Blackburn part number to spec for a 4 solid to 2/0 parallel double ground clamp?
Order Blackburn GH2TB. That is the manufacturer part number for the bronze parallel double clamp covering #4 solid through 2/0.
5) Do I get one clamp or a box when I order the GH2TB?
The GH2TB is sold each, one clamp per unit, not in a carton quantity. If you are standardizing a fleet of service replacements, order the count you need piece by piece.
6) Is the Blackburn GH2TB made in the USA?
Country of origin on the GH2TB is the United States. That matters on public and institutional work where domestic-sourcing language shows up in the specification.
