Blackburn ASL 500 NK – Frequently Asked Questions
1) What conductor size does the Blackburn ASL 500 NK lug take?
The ASL 500 NK is sized for 477 to 500 kcmil and 500 to 600 kcmil conductor. It is a compression lug, so the barrel is crimped onto the cable rather than set-screwed, and it is aluminum bodied for use on aluminum or copper conductor per the die chart on the tool. Anything smaller than 477 kcmil needs a different lug size.
2) Is the ASL 500 NK a two-hole lug, and can I stack lugs on the same pad?
Yes on both counts. It is a two-hole stacking compression lug, so it bolts down on NEMA two-hole spacing and is built to be stacked with another lug on the same bus or breaker pad, which is how you land parallel runs without adding a second pad. Overall length is 8-1/4 inches, so allow for that in the gutter or enclosure.
3) Does the Blackburn ASL 500 NK meet ANSI C119.4?
Yes. The lug is rated to ANSI C119.4, the standard covering connectors for use between aluminum and aluminum or aluminum and copper conductors. That is the spec most utility and institutional drawings call out for aluminum compression terminations.
4) Will this lug fit inside my panel or gutter?
Plan for 8-1/4 inches of length on the ASL 500 NK, measured overall. On a stacked pair that length plus the bend radius on 500 kcmil cable is usually what decides whether the termination fits, not the pad itself, so check clear depth in the gutter before you crimp.
5) Can I use a mechanical set-screw lug instead of this compression lug?
Not interchangeably. The ASL 500 NK is a compression type, so it requires a hydraulic crimper and the correct die for the barrel; there is no set screw. If you do not have crimping tooling on site, a mechanical set-screw lug in the same 500 kcmil range is the alternative, but it is a different connector and will not share this part number.
6) Is this lug insulated, and does it come plated or bare?
Bare finish, no insulation on the barrel. If the application needs a covered termination you will add heat shrink or a boot separately. Bare aluminum also means you should use a joint compound where the manufacturer's install instructions call for it on aluminum conductor.
7) Is the ASL 500 NK sold each or in a bag of ten?
Sold individually, one lug per unit. Count your terminations (two per parallel conductor if you are landing both ends) and order accordingly. It is made in the United States.
