Blackburn ASL 400 N – Frequently Asked Questions
1) What wire size does the Blackburn ASL 400 N compression lug take?
The ASL 400 N is sized for 400 kcmil conductor, and it also covers 397.5 kcmil ACSR/AAC stranding. It is a one-conductor compression barrel, so the cable has to be within that range for the die to form a proper crimp.
2) What does "stacking" mean on a two-hole NEMA lug like the ASL 400 N?
Stacking means the pad geometry lets you bolt a second lug on top of the first at the same two-hole pattern, so two conductors land on one bus pad or breaker stud. That is the reason to choose this over a plain two-hole lug: it is for parallel runs or doubled feeders where you only have one drilled pad.
3) Does the ASL 400 N need a crimp tool, or can it be bolted on?
It is a compression connection, so the barrel must be crimped with the correct hydraulic tool and die for the conductor. There is no set screw. The bolt holes are only for landing the pad on the bus or stud, not for retaining the cable.
4) Will the two-hole pad on the ASL 400 N line up with my NEMA drilled bus?
The pad is a NEMA two-hole pattern, which is the standard drilling used on switchgear bus, panelboard pads and transformer studs. Match the hole spacing and bolt diameter on your pad to be sure, since NEMA spacing varies with conductor size class.
5) Is the ASL 400 N lug aluminum or copper, and can I land it on a copper bus?
It is an aluminum-bodied lug (AL two-hole NEMA stack lug). Aluminum-bodied compression lugs of this type are built for aluminum conductor, and on ZenSupply the ASL 400 N is catalogued to ANSI C119.4, the standard covering aluminum and copper connectors for distribution conductors. For a straight copper-to-copper termination, specify a copper compression lug instead.
6) How much room do I need in the gutter or panel for the ASL 400 N?
Plan on 7-5/16 inches of length and 1-3/4 inches of width for the lug body and pad. Two-hole stacking lugs sit long, so check bending space to the enclosure wall before you commit to the location of the pad.
7) Is the Blackburn ASL 400 N made in the USA for a Buy American job?
Country of origin is the United States. On federally funded or Buy American specified work, that is the line item most procurement officers want confirmed before the submittal goes in.
8) Do I get a pair of lugs, or one?
The ASL 400 N sells each, one lug per unit. For a parallel stacked pair on a single pad, order two, and for a three-phase run with paralleled conductors count per termination point.
