Blackburn ASL30-21 – Frequently Asked Questions

1) Can the Blackburn ASL30-21 connector be used on both copper and aluminum conductors?
Yes. The ASL30-21 is a dual-rated mechanical connector, meaning it is rated for both copper and aluminum conductors. The body is aluminum with a tin plated finish, which is what allows it to be used on copper without the galvanic corrosion problem you get from bare aluminum on copper. Dual-rated bodies are typically marked AL9CU.
2) What wire range does the Blackburn ASL30-21 two-conductor lug take?
The ASL30-21 is built for 6 STR through 300 conductors, two conductors per lug, on a single hole mount. If your run is larger than 300 or smaller than 6 stranded, this is not the lug for it.
3) Is the ASL30-21 a one-hole or two-hole lug, and how many conductors does it take?
Single hole mount, two conductor. One bolt hole for the pad, two separate wire barrels, each with its own set screw. If your bus or ground bar is drilled for two-hole NEMA spacing, you need a different lug.
4) Do I need a crimp tool or die set to install the Blackburn ASL30-21?
No. It's a mechanical connector, so the conductors are secured with set screws rather than a compression die. All you need is the correct hex key or socket and a torque wrench to hit the torque value stamped on the lug. That makes it practical for field terminations and panel work where dragging a hydraulic crimper is not realistic.
5) Is the Blackburn ASL30-21 UL listed for panel and service entrance use?
The ASL30-21 carries UL file E9809. It's used for electrical panel connections, service entrance terminations, distribution system terminations, and wire splicing in commercial and industrial work.
6) Will the tin plating on this aluminum lug hold up in a damp or outdoor enclosure?
Tin plating over the aluminum body is there for corrosion resistance and a stable contact surface, which is why these are used at utility connection points and service entrances. For direct-burial or submerged work you still want the lug inside a rated enclosure and the aluminum conductors brushed and compounded per normal practice.
7) Is the Blackburn ASL30-21 sold individually or in a box?
Sold each. One ASL30-21 per unit, so order one per termination point rather than assuming a bag of ten. Manufacturer part number is ASL30-21 and it's made in Mexico.
