Blackburn GT6TB – Frequently Asked Questions
1) What conductor sizes does the Blackburn GT6TB ground clamp take?
The GT6TB parallel ground clamp is rated for copper conductors from 2/0 through 250 kcmil. If your grounding electrode conductor is smaller than 2/0, this is the wrong body size and you want a smaller parallel clamp in the same family.
2) Is the Blackburn GT6TB clamp copper or bronze, and can I use it on aluminum conductor?
The clamp body is bronze, and it is specified for copper conductors in the 2/0 to 250 kcmil range. For aluminum or AL/CU dual-rated runs you need a clamp marked for aluminum, not this one. Bronze on copper avoids the dissimilar-metal corrosion problem in damp vaults and direct-burial-adjacent work.
3) What is a parallel ground clamp used for versus a pipe or rod ground clamp?
A parallel clamp like the GT6TB joins two conductors running alongside each other, tapping a grounding or bonding conductor onto a larger run without cutting it. A pipe or rod clamp is a different animal: it wraps a water pipe or ground rod to terminate the electrode conductor. If you are landing on a rod or a cold water pipe, order a rod or pipe clamp instead.
4) Is the Blackburn GT6TB made in the USA for a Buy American job?
Country of origin on the GT6TB is the United States. That matters on federally funded and many institutional projects where domestic-origin electrical components are a submittal requirement. Confirm the specific clause on your contract, since origin alone is not the whole of every domestic preference rule.
5) What part number do I give my distributor for this Blackburn parallel ground clamp?
Order it as Blackburn GT6TB. That is the manufacturer part number, and it identifies the bronze parallel clamp for 2/0 through 250 kcmil copper.
6) Does the Blackburn GT6TB come as a single clamp or in a box quantity?
It sells as each, one clamp per unit, so order the count you need for the job rather than a carton. Useful for MRO shelf stock where you are replacing one or two connections at a time.
