Blackburn AL 350 N 20 HS – Frequently Asked Questions
1) What wire size does the Blackburn AL 350 N 20 HS aluminum lug take?
The AL 350 N 20 HS is sized for 350 kcmil conductor, with a stated range of 336.4 to 350 kcmil and 400 kcmil. It is a compression lug, so the barrel is crimped onto the conductor rather than set with a screw.
2) Is this a one hole or two hole lug?
Two hole. The AL 350 N 20 HS is a two hole compression lug, so the pad bolts to a bus or pad with two fasteners, which keeps the termination from rotating under torque or fault current.
3) Why is this aluminum lug 20 inches long?
The 20 inch length is the pigtail body of the lug, used where a long barrel is needed to reach from the conductor termination to a distant pad or through a tight enclosure without splicing. If your run does not need that reach, a standard short barrel 350 kcmil compression lug is the part to specify instead.
4) Does the AL 350 N 20 HS come insulated, and what is the heat shrink for?
The lug itself is uninsulated, listed with no insulation material. The heat shrink supplied with it is what you use to cover the barrel and the conductor transition after crimping, so plan on shrinking it in place as part of the termination rather than adding separate tape or tubing.
5) Can I use this aluminum lug on copper conductor?
It is an aluminum body lug rated to ANSI C119.4, the standard covering connectors for aluminum and copper conductors. Confirm the dual rating marking on the barrel before landing copper, and use the crimp die and tooling called out for that conductor. For a copper-only termination, a tinned copper two hole compression lug in 350 kcmil is the cleaner choice.
6) What standard does this Blackburn compression lug meet, and where is it made?
It is built to ANSI C119.4 and manufactured in the United States, which is what most institutional and government specs are looking for on a connector submittal.
7) Is the AL 350 N 20 HS sold each or in a bag?
Sold individually, one lug per unit, under part number AL 350 N 20 HS. Order one per conductor termination, so a three phase plus neutral feeder takes four.
