Blackburn GH1-TB – Frequently Asked Questions

1) What wire sizes does the Blackburn GH1-TB parallel clamp take?
The GH1-TB is rated for conductors from 8 AWG solid through 4 AWG stranded. If your grounding electrode conductor or bonding jumper falls outside that range, this is the wrong clamp for the run.
2) Is the Blackburn GH1-TB clamp bronze, and does that matter for direct burial or outdoor use?
Bronze is the conductor material on the GH1-TB. Bronze is the usual choice where a copper grounding conductor is involved, since it keeps the connection to similar metals and avoids the galvanic problem you get pairing copper with aluminum or steel bodies.
3) What is a parallel double clamp used for on a grounding job?
A parallel clamp like the GH1-TB joins two conductors running alongside each other rather than tapping a conductor to a rod or pipe. The double configuration means it takes two runs at once, which is what you want for a bonding jumper splice or tying a second ground conductor into an existing run.
4) Is the Blackburn GH1-TB sold individually or in a box of multiples?
Each. The GH1-TB is ordered one clamp at a time, so an electrician stocking a truck or a maintenance crew buying for a single panel bond does not have to take a carton.
5) Is the Blackburn GH1-TB ground clamp made in the USA?
Country of origin on the GH1-TB is the United States. That matters if you are buying against a government, school district, or federally funded spec with domestic sourcing language in it.
6) I need to order a Blackburn ground clamp by part number, what is it?
The manufacturer part number is GH1-TB, a Blackburn bronze parallel double clamp for 8 solid through 4 stranded conductors.
