Blackburn GR5TB – Frequently Asked Questions
1) What conductor sizes does the Blackburn GR5TB ground clamp accept?
The GR5TB takes grounding conductors from 4 AWG solid up to 2/0 stranded. Anything smaller than 4 solid or larger than 2/0 stranded needs a different clamp in the range.
2) Is the Blackburn GR5TB clamp body bronze, and does that matter for a buried or damp ground rod connection?
Bronze is the conductor material on the GR5TB. Bronze is the usual choice for grounding clamps because it resists corrosion and is galvanically compatible with copper conductors, which is what you want on a rod or water pipe connection exposed to moisture.
3) Is the Blackburn GR5TB made in the USA for a Buy American job?
Country of origin on the GR5TB is the United States, which is the line item a government, school, or federally funded project submittal usually asks for.
4) Do I need a separate lug, or does the GR5TB connect the grounding electrode conductor directly?
It's a one-piece ground clamp connector, so the grounding electrode conductor lands straight in the clamp, 4 solid through 2/0 stranded, with no intermediate lug or splice. You supply the conductor and the electrode.
5) Is the Blackburn GR5TB sold individually or in a box quantity?
Each. The GR5TB ships as a single clamp, so an electrician pulling one per service or per rod orders by the piece rather than by carton.
6) What is the Blackburn part number to quote for the 4 solid to 2/0 stranded ground clamp?
Order it as Blackburn GR5TB. That is the manufacturer part number for the bronze ground clamp connector covering 4 AWG solid through 2/0 stranded.
