Blackburn GG40250-2030 – Frequently Asked Questions
1) Will this Blackburn connector work for bonding a ground rod to a 4/0 grounding electrode conductor?
Yes, that is one of its two intended uses. The GG40250-2030 is a cable-to-cable or cable-to-rod connector rated for a 4/0 or 250 kcmil main, so a 4/0 copper electrode conductor to a ground rod is within its range. If your main run is smaller than 4/0 you need a different size in the E-Z-Ground compression family.
2) Is the Blackburn GG40250-2030 UL listed for grounding use on an inspected job?
It carries UL E3060 and CSA 2884, which is what an inspector or spec writer looks for on a grounding connection in the US and Canada.
3) Is this Blackburn E-Z-Ground connector suitable for copper grounding conductors?
Yes. The conductor material for the GG40250-2030 is copper, so it is intended for copper grounding electrode conductors and copper bonding jumpers, not aluminum.
4) Can I use a mechanical set screw lug instead of a compression grounding connector like this?
Different install method, and it changes your tooling. The GG40250-2030 is a compression fitting, so it is crimped with a hydraulic or battery compression tool and the joint is permanent and irreversible once made. A mechanical connector tightens with a wrench and can be taken apart, but compression is what most specs call for on buried or direct-earth grounding where a screw joint can loosen. If you do not have a compression tool on the truck, do not order this one.
5) Does the Blackburn GG40250-2030 come as a single connector or in a bag of multiples?
Sold each. The selling unit is one connector, so quantity on the order equals the number of grounding taps you are making.
6) What part number and country of origin should I put on a submittal for this Blackburn grounding connector?
Manufacturer part number GG40250-2030, Blackburn brand, made in Mexico, with UL E3060 and CSA 2884 listings for the standards line of the submittal.
