Blackburn GR12-306 – Frequently Asked Questions
1) What crimp die does the GR12-306 compression connector take?
It crimps with an 87H die. You need a compression tool set up for the 87H die index to make a listed connection on this connector; hand-tightening or the wrong die is not a compliant install.
2) Is the Blackburn GR12-306 UL listed for direct burial grounding?
It carries UL E3060 plus CSA 4503 and CSA 2884. That is the compression grounding listing electrical inspectors look for on a ground rod connection, which matters when the connector is going in a trench or under a slab where it cannot be re-worked later.
3) Is the GR12-306 grounding connector copper, and will it corrode against a copper-bonded rod?
The conductor material is copper, so you are joining copper to a copper-bonded ground rod and copper grounding electrode conductor. Same-metal contact avoids the galvanic corrosion you get when dissimilar metals are buried together.
4) Why use a compression pigtail connector instead of an acorn clamp on a ground rod?
A pigtail compression connector like the GR12-306 is crimped once with a die (87H here) and is not serviceable, which is exactly why inspectors accept it for direct burial and concrete encasement. A bolted acorn clamp relies on torque that can loosen or corrode and generally wants to stay accessible. If the connection is getting buried or poured over, go compression.
5) Is the Blackburn GR12-306 sold individually or in a bag quantity?
It is sold each, one connector per unit, under part number GR12-306. Order the count you need for the job rather than a fixed pack.
6) Is the Blackburn GR12-306 made in the USA for jobs with domestic sourcing requirements?
Country of origin is the United States, which is what government, school district, and federally funded projects usually need documented on grounding and bonding material.
