Blackburn AL 2300-4 NEHV – Frequently Asked Questions
1) What conductor size does the Blackburn AL 2300-4 NEHV compression lug take?
The AL 2300-4 NEHV is sized for 2000 kcmil conductor. It is a one-size compression barrel, so it is not a range connector: the cable has to be 2000 kcmil for the crimp to be correct.
2) Is the Blackburn AL 2300-4 NEHV a two-hole or four-hole lug?
Four-hole. It's a four-hole compression lug with a straight (in-line) tongue, so it bolts flat to a four-hole NEMA drilled pad rather than a two-hole pattern. If your bus or breaker pad is drilled for two bolts, this is the wrong tongue.
3) How big is this 2000 kcmil aluminum lug, and will it clear inside my gear?
Overall size is 18-1/2 inches by 4 inches wide. That is a large terminal, so check cabinet depth, bending space for the cable, and phase spacing before you commit to it in a switchboard or panel section.
4) Can I use this Blackburn lug on copper cable, or is it aluminum only?
It's an aluminum-bodied compression connector. Blackburn aluminum compression lugs of this type are dual-rated bodies in many cases, but what's on record here is the aluminum construction and the 2000 kcmil conductor size, so specify by those. For a copper-only termination, a copper compression lug of the same 2000 kcmil size and four-hole NEMA pattern is the direct alternative.
5) What standard does the AL 2300-4 NEHV compression connector meet?
It is built to ANSI C119.4, the standard covering connectors for aluminum and copper conductors. That is the reference most utility and industrial specs call out for compression terminations, so it satisfies a spec line written to C119.4.
6) Does this Blackburn connector bolt on or do I need a crimp tool?
It's a compression connector, not a mechanical set-screw lug. You need a hydraulic crimper with the correct die for a 2000 kcmil aluminum barrel; there are no screws to torque on the conductor side. Only the four bolts at the pad get torqued.
7) Does this lug come insulated or do I need to cover it myself?
No insulation on it. The barrel and tongue are bare, so any covering, boot, or taping over the crimp is on you as part of the termination.
8) Is the Blackburn AL 2300-4 NEHV sold individually or in a bag?
Sold each. Order one per conductor termination, so a three-phase plus neutral run needs four.
9) Is this aluminum compression lug made in the USA for a domestic-preference job?
Country of origin is the United States, which is what buyers on federally funded or Buy American specified work need on the submittal.
