Blackburn 54890 – Frequently Asked Questions
1) What conductor sizes does the Blackburn 54890 grounding connector take?
The Blackburn 54890 is a Figure 6 compression connector sized for a 250 through 500 kcmil main run with a 1/0 to 2/0 tap. If your main is smaller than 250 kcmil or your tap is larger than 2/0, this is the wrong die-size connector for the joint.
2) Is the Blackburn 54890 a compression fitting or a bolted mechanical lug?
Compression. It is an E-Z-Ground compression connector, so it is crimped with a hydraulic tool and the correct die, not torqued down on a bolt. If you need something you can loosen and re-land later, use a mechanical grounding lug instead.
3) What is the Blackburn 54890 made of, and can it be direct buried in a ground grid?
It is copper, which is the standard material for irreversible compression connections on copper grounding electrode conductors and ground grid taps.
4) What does a FIG 6 configuration mean on a grounding compression connector?
Figure 6 designates the geometry of the joint: a continuous main run with a tap conductor coming off it, crimped in one sleeve. On the 54890 the main is 250 to 500 kcmil and the tap is 1/0 to 2/0. Pick the figure number by how the conductors meet at the point, then the size range by the two cables.
5) Is the Blackburn 54890 made in the USA for a Buy American job?
Country of origin is the United States, which is what a government or institutional procurement file usually needs documented on grounding materials.
6) Can I reuse a Blackburn 54890 if I have to re-route the ground conductor?
No. A compression connector forms a permanent, irreversible joint once crimped; cut it out and install a new one. Budget spares if the layout is still moving.
