Blackburn AL 1590-4 N – Frequently Asked Questions
1) What conductor size does the Blackburn AL 1590-4 N compression lug take?
The AL 1590-4 N is sized for 1590 kcmil conductor, and also listed for 1272 kcmil 45/7 ACSR. It is a compression connection, so it gets crimped onto the conductor with the matching die, not bolted or set-screwed.
2) Is the Blackburn AL 1590-4 N a four hole NEMA pad lug?
Yes. It is a four hole straight lug with a NEMA drilled pad, so it lands on equipment pads with four bolt holes on standard NEMA spacing. Overall it measures 13-1/2 inches long by 3 inches wide, which matters if you are working in a tight cabinet or close to a barrier.
3) Does the Blackburn AL 1590-4 N meet ANSI C119.4?
Yes, the lug is built to ANSI C119.4, the standard covering connectors for aluminum and copper conductors. That is the reference a utility or institutional spec usually calls out for a compression connector at this size.
4) Can this aluminum lug be used on copper conductors?
The AL 1590-4 N is an aluminum body with a tin plating. Tin plated aluminum bodies of this type are dual rated in practice, but what is on record here is the conductor range: 1590 kcmil and 1272 kcmil 45/7 ACSR. Match the die and the conductor size to that. For a copper-only run, specify a copper compression lug in the same kcmil size instead.
5) Does this lug come insulated or do I need to cover it after crimping?
No insulation on it. The AL 1590-4 N ships bare, so any covering, boot, or tape barrier over the crimp and pad is a separate item you supply on the job.
6) Is the Blackburn AL 1590-4 N made in the USA for Buy American jobs?
Country of origin is the United States, which is what government, healthcare, and education procurement usually needs documented on a domestic preference job.
7) Should I use a four hole lug or a two hole lug on a 1590 kcmil termination?
At 1590 kcmil you are typically on a large switchgear or transformer pad, and the four hole NEMA pattern spreads the current and clamping force across four bolts rather than two. Use the four hole version when the equipment pad is drilled for four; if the pad only has two holes on standard NEMA centers, a two hole lug in the same conductor size is the right part instead.
8) Is the Blackburn AL 1590-4 N sold individually or in a pack?
Sold each. One lug per unit, so on a three phase plus neutral termination you order four, and add spares if you want margin on a bad crimp.
