Blackburn AL 600 N 32 HS – Frequently Asked Questions
1) What wire size does the Blackburn AL 600 N 32 HS compression lug take?
The AL 600 N 32 HS is sized for 550 to 600 kcmil conductor, and also covers 477 (26/7) ACSR. If your feeder is smaller than 550 kcmil, this barrel will not compress properly on it and you need the next size down in the series.
2) Is this an aluminum lug, and can I use it on copper conductor?
It is a tin plated aluminum body lug. Tin plating on aluminum is what makes it dual rated in practice for aluminum or copper conductor, and it is built to ANSI C119.4, the standard for connectors used on aluminum and copper conductors. If your job spec calls for a copper-only connector, specify a copper barrel lug instead.
3) Is the Blackburn AL 600 N 32 HS a crimp lug or a mechanical set screw lug?
Compression. The barrel is crimped onto the conductor with a hydraulic or battery compression tool and the correct die, so there is no set screw to re-torque later. If you want a connector you can install with a hex key and no crimp tool, you want a mechanical lug, not this one.
4) Will a two hole NEMA lug bolt to my switchgear bus pad?
Yes, the tongue is a two hole NEMA drilled pad, which is the standard bolt pattern on switchgear, panelboard, and transformer bus pads. Two bolts stop the lug rotating under fault current, which is why most utility and gear specs call for two hole rather than one hole on large feeders.
5) Does this lug come with heat shrink, or do I buy that separately?
Heat shrink is supplied with it, the HS in AL 600 N 32 HS. The lug itself has no insulation on the body, so the shrink sleeve is what you use to seal and cover the barrel and conductor transition after crimping. Nothing else to order for the insulation.
6) What does ANSI C119.4 mean for a utility or institutional spec sheet?
ANSI C119.4 is the performance standard for electric connectors used on aluminum and copper conductors, covering heat cycling and current cycling performance. The AL 600 N 32 HS is built to it, so it satisfies spec language that calls for C119.4 compliant compression connectors on 600 kcmil feeders.
7) How is the Blackburn AL 600 N 32 HS sold, and is it made in the USA?
Sold each, one lug per unit, so order one per conductor termination. Country of origin is the United States, which matters if you are on a Buy American or federally funded project.
