Blackburn LAC150 – Frequently Asked Questions
1) What wire size does the Blackburn LAC150 compression lug take?
The LAC150 is sized for 400 to 500 kcmil conductor. Anything smaller than 400 kcmil will not compress correctly in the barrel, so step down to a lug rated for your actual conductor rather than trying to build up the cable.
2) Is the LAC150 rated for 90 degree C conductor in a 600 volt panel?
Yes. The LAC150 carries a 600 V rating and a 90 degree C temperature rating, which covers THHN/THWN-2 and XHHW-2 feeders landed in a standard 600 V distribution panel or disconnect.
3) Do I need a crimp tool for the Blackburn LAC150, or can it be set with a wrench?
It is a compression connector, not a mechanical set-screw lug, so it has to be crimped with a hydraulic or battery compression tool using the die called out by the color code on the barrel. There are no set screws to tighten. If you want a wrench-only install, use a mechanical screw-type lug for 400 to 500 kcmil instead.
4) Can I use the Blackburn LAC150 lug on copper conductor, or is it aluminum only?
The LAC150 is an aluminum-bodied compression terminal lug with a bare surface finish and no insulation. Aluminum compression lugs of this style are commonly listed AL9CU for both aluminum and copper, but the dual-rating marking is not part of the LAC150 spec data here, so work from the marking stamped on the lug body itself when the conductor is copper.
5) What does a one-slot slotted tang mean for bolting this lug to a bus bar?
A slotted tang gives you an open slot instead of a drilled round hole, so the lug slides onto an already-installed stud or bolt rather than having to come off. The LAC150 has a single slot, meaning one bolt per lug, so it lands on a single-hole bus pad or breaker terminal. If your bus pad is drilled two-hole on NEMA centers, you need a two-hole tang lug instead.
6) What is the aqua color band on this Blackburn lug for?
Aqua is the die color code on the LAC150 barrel. It tells the installer which die set and crimp position to use in the compression tool, so the crimp matches the 400 to 500 kcmil conductor the lug is built for. Match the tool die to aqua, not to the cable size alone.
7) Is the LAC150 lug insulated or does it need taping after the crimp?
Bare, with no insulation on the body. In an enclosure where the tang and barrel could come near a grounded surface or an adjacent phase, plan on insulating boots or tape over the finished crimp. Order the boot separately, nothing is included with the lug.
8) Are Blackburn LAC150 lugs sold individually or in a bag?
Sold each, so the quantity you order is the number of lugs you get. For a three-phase plus neutral 400 kcmil feeder termination at both ends, that is eight pieces. Made in the United States.
