Blackburn ATL250-12 – Frequently Asked Questions

1) Can I use the Blackburn ATL250-12 lug on copper conductors, or aluminum only?
The ATL250-12 is an aluminum-bodied compression lug sized for 250 kcmil cable. Aluminum compression connectors are only suitable for copper when the manufacturer marks them AL9CU dual-rated; this one is catalogued as an aluminum lug for aluminum conductor, so for a 250 kcmil copper run you want a copper compression lug instead. If you are terminating aluminum conductor, this is the right family, and you should still use a listed oxide-inhibiting compound on the strands before crimping.
2) Is the ATL250-12 a compression lug or a mechanical set-screw lug?
Compression. It has to be crimped with the proper die and hydraulic or battery tool, not tightened with a hex key. If you do not have a compression tool on the truck, a mechanical (set-screw) lug for 250 kcmil is the practical choice instead. The tradeoff is that a compression termination is a permanent, factory-repeatable connection with no torque to re-check, which is why spec jobs and utility work call for it.
3) Is the Blackburn 250 kcmil aluminum lug UL listed for panel and switchgear work?
Yes, it carries UL listing under file E9809, which is what an inspector or a spec writer will want to see on a 250 kcmil termination in power distribution panels, switchgear, motor control centers and substation work.
4) What does the red color on this Blackburn lug mean?
Red here is the die color code, the identifier for the crimp die/index required for this connector barrel. Match the red die group on your compression tool to the lug. It also gives crews a quick visual check that the right size lug went on the right cable during inspection.
5) Do I get one lug or a pack when I order the Blackburn ATL250-12?
Sold each, so a three-phase plus neutral termination needs four pieces ordered. Worth counting both ends of the run plus a spare or two, since a mis-crimped compression lug cannot be reused.
6) What is the exact part number to order for the Blackburn 250 kcmil one-hole 1/2 inch lug?
Blackburn ATL250-12. The number reads directly: ATL for the aluminum terminal lug series, 250 for the 250 kcmil conductor, and 12 for the 1/2 inch stud hole. Country of origin is Mexico.
