Blackburn AL 400 N 16 HS – Frequently Asked Questions
1) What conductor size does the Blackburn AL 400 N 16 HS lug take?
The AL 400 N 16 HS is sized for 397.5 to 400 kcmil and 350 kcmil conductor. The product name also calls it out for 4/0, so check the conductor you are terminating against those ranges before you crimp, since a compression lug only holds its rating on the barrel size it was built for.
2) Is this a bolt-on or a crimp lug?
Crimp. The AL 400 N 16 HS is a compression lug, so it goes on with a hydraulic or battery crimp tool and the correct die, not a setscrew wrench.
3) Does the Blackburn AL 400 N 16 HS have one or two bolt holes at the pad?
Two. It is a two hole straight NEMA pad lug, which is what you want landing on a two hole busbar or breaker pad where a single bolt would let the lug rotate.
4) Does the AL 400 N 16 HS meet a recognized connector standard for my spec submittal?
It is built to ANSI C119.4, the standard covering connectors for aluminum and copper conductors, which is the line most utility and commercial specs reference for compression connectors.
5) Why is this lug 16 inches long?
The 16 inch length is the long barrel version, used where you need to reach across a gutter or between a conductor termination and a distant pad without splicing. Allow for that 16 inches of straight run in the enclosure when you plan bending space.
6) Does this Blackburn lug come insulated or with a boot?
Bare. There is no insulation on the lug itself, so any phase taping, heat shrink or boot is a separate item on your material list.
7) What part number do I order for the Blackburn 4/0 two hole long barrel lug with heat shrink?
AL 400 N 16 HS is the catalog number, from Blackburn. That single number covers the aluminum two hole straight NEMA pad compression lug in the 16 inch length.
8) Is this lug made in the USA, and is it sold individually?
Made in the United States and sold each, so order one per conductor termination rather than expecting a bagged pair.
