Blackburn AL 1590-4NN – Frequently Asked Questions
1) What conductor size does the Blackburn AL 1590-4NN compression lug take?
One 1590 kcmil conductor. The barrel is sized for that single cable only, so smaller conductors need a lug matched to their kcmil size rather than this one, and there is no range here to work within.
2) How much room do I need in the cabinet for this 1590 kcmil lug?
Plan on 16.187 inches of overall length, with 10.813 inches of that being the crimp barrel. That is a long straight lug, so in a tight termination compartment check bending space and phase clearance before you commit to it.
3) Is this a crimp lug or a mechanical set-screw lug?
Compression only. The AL 1590-4NN is crimped with a hydraulic tool and die matched to the barrel, so if you want a field-installable connection with no crimp tool you need a mechanical set-screw lug instead.
4) Does this lug meet the standard my spec calls out for connectors?
It is built to ANSI C119.4, the standard covering connectors for aluminum and copper conductors. That is the reference most utility and industrial termination specs cite for compression connectors.
5) Does the AL 1590-4NN come with insulation or a cover?
No insulation, no boot. It is a bare tin-plated aluminum barrel and pad, so any phase taping, heat shrink or cover for the barrel and exposed pad has to be ordered separately.
6) Is this lug sold each or in a box quantity?
Sold individually, one lug per unit. For a three-phase plus neutral termination set you order four, and spares for re-crimps should be added since a compression lug cannot be reused once crimped. Made in the United States.
