Blackburn GR34-202 – Frequently Asked Questions
1) Will the Blackburn GR34-202 fit a 3/4 inch ground rod?
Yes. The GR34-202 is sized for 3/4 inch ground rod, which is the common driven rod diameter on commercial and residential services. It is a figure 8 compression connector, so the rod sits in one eye of the die and the conductor in the other, and both are crimped in a single pass with a compression tool.
2) What size conductor does the Blackburn GR34-202 grounding connector accept?
It takes copper conductor from 2 AWG through 2/0 AWG. If your grounding electrode conductor is 4 AWG or smaller, or larger than 2/0, this is the wrong die range and you need a different figure 8 body.
3) Is the GR34-202 a UL listed ground rod connector for direct burial?
The GR34-202 carries UL file E3060. It is a copper compression connector for grounding electrode terminations, the usual application for which is a driven rod below grade.
4) Compression ground rod connector or a bolted acorn clamp, which should I use?
A bolted acorn clamp can be installed with a wrench and can be taken apart later; a compression connector like the GR34-202 needs a hydraulic or battery crimp tool and the correct die, and it is permanent once crimped. Electricians choose the compression figure 8 when they want a termination that cannot loosen from soil movement or vibration and does not need re-torquing on inspection.
5) Can I use aluminum wire with the Blackburn GR34-202?
No. The conductor material for this connector is copper. Use a connector rated for aluminum if your grounding conductor is AL or an AL/CU listed body.
6) Is the Blackburn GR34-202 sold individually or in a bag of multiples?
The GR34-202 sells by the each, so one connector per unit ordered. Contractors grounding a run of rods should count one per rod-to-conductor termination.
7) Is the Blackburn GR34-202 made in the USA?
Country of origin on the GR34-202 is the United States, which matters if you are procuring against a domestic-content requirement on a public project.
