Blackburn ASL 800 NTN AL 2HOLE NEMA LUG W/STACK 800 795

The ASL 800 NTN is sized for 800 kcmil conductor. It's a compression lug, so it's crimped onto the cable with a die-and-tool setup rather than torqued down on a setscrew. If your cable is a different kcmil size, you need a different lug in the series, not this one.

Yes, it's a two-hole NEMA pattern lug, so it lands on standard NEMA drilled pads and busbar rather than a single-bolt pad. Two-hole mounting keeps the lug from rotating under fault current, which is why it's specified on switchgear and transformer pads.

Stacking means the tongue is made to sit one lug on top of another on the same two-hole pad, so you can land multiple 800 kcmil conductors on a single termination point without adding a second pad. Bolt length has to be long enough for the combined tongue thickness plus the pad, and you still land the stack in line with the pad's hole pattern.

It's built to ANSI C119.4, the standard covering connectors for aluminum and copper conductors. That's the reference most utility, industrial and institutional specs cite for compression connectors, so it can be listed against a drawing calling out C119.4.

The body is aluminum with a tin plating. The tin plate is what lets it bolt to a copper bus or pad without a direct aluminum-to-copper interface at the joint. The barrel itself is aluminum, so match it to the conductor material your spec calls for and use the correct compression die for the barrel.

Overall size is 8-5/16 x 1-3/4 inch wide. That's a long barrel, so check bending space and the distance from the pad to the enclosure wall before you commit, especially in a tight gutter or a compartment where the cable has to make a turn right off the termination.

Country of origin is the United States, which is what a federal, state or institutional job with domestic-content language on electrical materials needs documented. The manufacturer part number to cite is ASL 800 NTN.

Compression, like the ASL 800 NTN, needs a hydraulic crimper and the matching die, but it gives a one-time permanent joint with no torque to re-check later. A mechanical setscrew lug installs with just a torque wrench and can be taken apart, which suits maintenance-access terminations. If the spec calls out ANSI C119.4 compression connectors, a setscrew lug won't substitute.

It's sold each, so quantity is per lug. On a three-phase feeder with a neutral you're ordering four per termination point, doubled if you're landing both ends, and more again if you're stacking parallel runs.
