Blackburn GG2030-21 – Frequently Asked Questions
1) What conductor sizes does the Blackburn GG2030-21 grounding connector take?
The GG2030-21 is built for a 2/0 or 3/0 main run with a 1/0 tap. Both the main and the tap have to fall in those sizes for the die to crimp correctly, so a 4/0 main or a #2 tap needs a different catalog number in the E-Z-Ground line.
2) Can I use the GG2030-21 to connect a ground wire to a ground rod, or is it cable to cable only?
Both. The GG2030-21 is a cable-to-cable and cable-to-ground-rod compression connector, so it covers a tap off a grounding electrode conductor as well as the run down to the rod, as long as the conductors are 2/0 or 3/0 main and 1/0 tap.
3) Does the GG2030-21 grounding connector carry a UL listing for an inspected job?
It is covered under UL E3060 and CSA 2884, so it can be submitted on both US and Canadian work. Those file numbers are what an inspector or a submittal package will be looking for.
4) Is the Blackburn GG2030-21 copper or aluminum?
Copper. That matters on a grounding electrode system because mixing a copper connector onto aluminum conductors invites galvanic corrosion, particularly in direct-burial or damp locations. Use it on copper grounding conductors.
5) Do I need a special crimping tool for the Blackburn E-Z-Ground GG2030-21?
Yes, it is a compression connector, not a mechanical lug, so it is installed with a hydraulic or battery crimper and the matching die set. There is no bolt or set screw to torque. Plan the tool into the job if your crew is only carrying mechanical connectors.
6) Can a compression ground connector like the GG2030-21 be direct buried or encased in concrete?
Compression grounding connectors are the usual choice where a mechanical connector cannot be inspected, such as a direct-buried or concrete-encased splice, because the crimp is irreversible and there is no hardware to loosen. The GG2030-21 is copper, so keep it on copper conductors in those locations.
7) Is the GG2030-21 sold in bags or individually?
Each. The selling unit is a single connector, so order the exact count of taps you have rather than a multiple of a bag quantity.
8) What is the manufacturer part number and country of origin for the Blackburn GG2030-21?
Blackburn part number GG2030-21, made in Mexico. Quote it by that number, since the neighboring GG catalog numbers cover different main and tap size combinations.
