Blackburn AL 350 N 24 HS – Frequently Asked Questions
1) What conductor size does the Blackburn AL 350 N 24 HS lug take?
The AL 350 N 24 HS is sized for 336.4 to 350 kcmil conductor, and also covers 400 kcmil per the wire size range listed. It is a compression lug, so it is crimped onto the conductor with a die rather than torqued down on a setscrew.
2) Can I use this aluminum compression lug on copper conductor?
It's an aluminum-body lug built for aluminum conductor at 336.4 to 350 kcmil. If you're terminating copper of the same size, order a copper compression lug instead, or a dual-rated AL9CU barrel. Putting aluminum-only hardware on copper is not the right termination.
3) Is this a one hole or two hole lug?
Two hole. The pad is drilled for a two-bolt NEMA pattern, which resists rotation under fault current and is what most utility and switchgear specs call for on 350 kcmil terminations. If your bus is drilled for a single bolt, you need a one hole lug instead.
4) Does this Blackburn lug come with heat shrink, or do I buy that separately?
Heat shrink is supplied with it (the HS suffix in AL 350 N 24 HS). The lug barrel itself is uninsulated, so the shrink sleeve is what you use to seal and insulate the crimp after compression. You still need a heat gun and a compression tool with the correct die.
5) Why is this lug 24 inches long?
The 24 inch length is the barrel/pigtail extension, which lets you land the pad at a distant bus or ground bar without splicing in extra conductor. It's a long-barrel style lug, not a standard short-barrel terminal, so allow for that reach in your enclosure or handhole layout.
6) Will this lug meet a utility spec calling for ANSI C119.4 connectors?
Yes, the AL 350 N 24 HS is built to ANSI C119.4, the standard covering electric connectors for use between aluminum and aluminum or aluminum and copper bare conductors. That is the reference most utility and municipal submittals cite for compression connectors.
7) Is the Blackburn AL 350 N 24 HS sold each or in a box?
Sold individually, one lug per unit, with its heat shrink sleeve. Order one per termination, and remember a three-phase feeder plus neutral means four.
8) Is this lug made in the USA for a Buy American job?
Country of origin is the United States, which is what most federally funded and municipal procurement packages want documented on electrical connectors.
