Blackburn GG500-2030 GRN ROD CONN

It's a ground rod connector from Blackburn's E-Z-Ground compression grounding line, used to terminate a grounding conductor to a driven ground rod. The connector is copper, so it pairs with copper grounding electrode conductors without introducing a dissimilar metal at the joint.

Compression. It belongs to the E-Z-Ground compression grounding family, which means it is crimped with a compression tool and die rather than tightened with a set screw. That matters on the job: a compression connection is irreversible and needs the correct die, but it has no bolt to back off and is accepted for direct burial applications where mechanical clamps often are not. If you want a connection you can take apart later for testing, use an acorn-style mechanical ground rod clamp instead.

It is listed under UL file E3060. That's the reference an inspector or a spec reviewer will want for a grounding electrode connection, so keep it with the submittal package.

The connector body is copper, so it is intended for copper grounding conductor. Putting aluminum into a copper compression barrel creates a dissimilar-metal joint that corrodes, particularly in the wet, direct-burial conditions a ground rod connection sits in. For aluminum conductor, specify a connector rated for aluminum or a dual-rated AL/CU device.

The GG500-2030 is sold each, so one connector per unit ordered. If you're grounding a run of rods or standardizing a service upgrade across multiple buildings, order to your rod count.

Country of origin is the United States. That is the detail federal, municipal, and institutional procurement offices ask for on grounding and bonding submittals, so it can be cited directly on a Buy American certification.

Quote it as Blackburn GG500-2030. That is the manufacturer part number, and it's the identity to match when a distributor or a wholesaler is cross-referencing an E-Z-Ground compression grounding connector against a bid list.
