Blackburn 54900 – Frequently Asked Questions
1) What conductor sizes does the Blackburn 54900 grounding connector take?
The Blackburn 54900 is a Figure 6 compression connector sized for a 250 through 500 kcmil main (run) conductor with a 350 to 250 kcmil tap. If your main run is smaller than 250 kcmil or your tap falls outside that band, you need a different figure/size in the E-Z-Ground compression line rather than this one.
2) Is the Blackburn 54900 connector copper, and can I use it on aluminum conductors?
The 54900 is copper. Copper compression connectors are made for copper grounding conductors; for aluminum or mixed copper-to-aluminum runs you need a connector rated AL/CU, so don't substitute this one on an aluminum ground.
3) Is the Blackburn 54900 a compression connector or a mechanical bolted lug?
It's a compression fitting, not a bolted mechanical connector. You crimp it with a hydraulic or battery compression tool and the correct die for the barrel size; there are no set screws or bolts to torque, and it is not reusable once crimped.
4) What is the 54900 used for on a grounding electrode system?
It's a grounding connector for splicing or tapping large copper grounding conductors, the kind of joint used on grounding electrode conductors, ground grids, and ground bar feeds in service and substation work. The Figure 6 body handles a 250 to 500 kcmil main with a 350 to 250 kcmil tap coming off it.
5) Does the Blackburn 54900 carry a listing or standard for inspection?
It is built to CSA 4503. That is the reference to cite if an inspector or spec reviewer asks what standard the compression grounding connector is made to.
6) What Blackburn part number do I order for this size grounding connector?
Order Blackburn part 54900. That's the manufacturer number for the Figure 6 compression grounding connector covering a 250 to 500 kcmil main with a 350 to 250 kcmil tap.
7) Is the Blackburn 54900 sold individually or in a box?
Sold each, so one connector per unit ordered. Count one per joint plus spares, since a mis-crimped compression connector has to be cut out and replaced.
8) Is the Blackburn 54900 made in the USA for Buy American jobs?
Country of origin on the 54900 is the United States, which is what procurement on federal, municipal, and utility work usually needs documented for domestic-content requirements.
