Blackburn GG40250-21 – Frequently Asked Questions
1) What conductor sizes does the Blackburn GG40250-21 grounding grid connector take?
The GG40250-21 is a compression grid connector for a 4/0 or 250 kcmil run conductor with a No. 2 or No. 1 tap. Both legs are sized for copper conductor. If your run is smaller than 4/0 or your tap falls outside No. 2 to No. 1, you need a different die-numbered connector in the E-Z-Ground family.
2) Can I use this Blackburn grid connector on aluminum ground conductor?
No. The GG40250-21 is rated for copper conductor only. For aluminum grounding runs you need a connector specifically listed for aluminum or dual-rated AL/CU.
3) Do I need an exothermic weld or will a compression grid connector work for tapping a ground grid?
A compression connector like the GG40250-21 does the same job as an exothermic weld for a run-to-tap grid connection without molds, powder, or an ignition permit, and it is UL and CSA listed for grounding use. Choose compression when you want a repeatable crimp made with a die tool in the trench; choose exothermic when a spec explicitly calls for a welded connection.
4) Is the Blackburn GG40250-21 sold individually or in a bag?
It ships as an each, one connector per unit, so you can order the exact count of taps on the grid rather than a bulk carton. Country of origin is Mexico.
