Blackburn ASL75-42 – Frequently Asked Questions
1) Can the Blackburn ASL75-42 lug be used on copper conductors as well as aluminum?
Yes. The ASL75-42 is a dual-rated mechanical connector, so it lands both aluminum and copper conductors. The body is aluminum with a tin plating, which is what lets it sit against copper without the dissimilar-metal problem you get with a bare aluminum lug.
2) What wire sizes does the Blackburn ASL75-42 four-conductor lug take?
It accepts conductors from 3/0 stranded up through 750 kcmil, in four separate ports. That range covers typical feeder and service conductors, so one lug can land four runs of mixed sizes within that window.
3) How does the ASL75-42 mount to a bus bar or panel pad?
Two-hole mounting. The ASL75-42 bolts flat to a pad or bus with a two-bolt pattern rather than a single stud, which keeps it from rotating under torque on heavy 750 kcmil conductors.
4) Do I need a crimp tool to install the Blackburn ASL75-42?
No. This is a mechanical connector, so the conductors are secured with set screws and torqued to spec. No hydraulic crimper or die set is required, which is why these get used for field terminations and service upgrades where crimp gear is not on the truck.
5) Is the ASL75-42 sold individually or in a box?
Sold each. One lug per unit, so order the exact count of terminations you need rather than a carton quantity.
6) What is the exact part number and country of origin for this Blackburn four-conductor lug?
The manufacturer part number is ASL75-42, made in Mexico. That is the number to quote when matching an existing installation or building out a submittal.
