Blackburn GG500-40250 – Frequently Asked Questions
1) What conductor sizes does the Blackburn GG500-40250 compression grounding connector take?
The GG500-40250 is set up for a 500 kcmil main run with a 350 kcmil tap. Main and tap are fixed by the die/connector combination, so if your run conductor is something other than 500 kcmil or your tap is not 350 kcmil, you need a different GG part number rather than this one.
2) Can I use this Blackburn connector to attach a grounding electrode conductor to a ground rod?
Yes. The GG500-40250 is a cable-to-cable / cable-to-rod compression connector, so it will take a tap conductor to a run of cable or to a driven ground rod. It is a copper connector for copper conductors.
3) Is the Blackburn GG500-40250 listed for grounding use by an inspector?
It carries UL file E3060 and CSA 2884 for grounding and bonding use, which is what an electrical inspector looks for on a grounding electrode or bonding connection.
4) Is this an irreversible compression connection or a mechanical clamp?
It is a compression connector, crimped with a hydraulic tool and the matching die, not a bolted or set-screw clamp. Blackburn lists it in its E-Z-Ground compression grounding line. If you need a connection you can take apart later for testing, use a mechanical grounding clamp instead.
5) Will this compression connector work on aluminum conductors?
No. The GG500-40250 is a copper connector intended for copper conductors. For aluminum run or tap conductors, specify a connector rated for aluminum or dual-rated AL/CU, since copper-only compression bodies are not approved for aluminum.
6) Do Blackburn GG grounding connectors come in a bag or are they sold one at a time?
Sold individually, each. Order the quantity of connections you have to make; count one per tap point on the ground grid or rod.
7) Where is the Blackburn GG500-40250 manufactured?
Manufacturing is in Mexico. Useful if you are tracking country of origin for a government or institutional job with sourcing documentation requirements.
