Blackburn ASL 350-48 TN – Frequently Asked Questions
1) What conductor size does the Blackburn ASL 350-48 TN lug take?
The ASL 350-48 TN is sized for 350 kcmil conductor. It is a compression lug, so the barrel is crimped onto the cable with a die tool rather than tightened with a set screw. One size only, so if your feeder is 250 or 500 kcmil you need the matching lug in that range instead.
2) What bolt size is the pad hole drilled for on this Blackburn stacking lug?
One hole, drilled for a 1/2 inch bolt. Match that against the stud or bus drilling on your panel, transformer, or switchgear pad before ordering, because the pad is not field-drillable to a larger stud.
3) What does the "stacking" in this compression lug actually mean on the job?
A stacking lug has an offset pad so two or more lugs can be bolted on the same 1/2 inch stud without the barrels colliding. That is what you want when you are landing multiple 350 kcmil feeders on a single termination point in a panelboard or transformer. A standard flat one-hole lug will not stack cleanly.
4) Can I use this aluminum lug on copper conductor?
The ASL 350-48 TN is an aluminum-body lug with a tin-plated finish, which is the standard dual-rated construction for terminating either aluminum or copper 350 kcmil conductor. The tin plating is also what lets you bolt it to a copper or aluminum pad without a bare aluminum-to-copper interface.
5) Is this lug insulated, and do I need to cover it after crimping?
No insulation on this one. The barrel is bare tin-plated aluminum, so in any application where you need the termination covered you add heat shrink or a boot separately. That is normal for kcmil-size compression lugs landing inside gear.
6) How much room do I need in the gutter for this 350 kcmil lug?
Overall length is 4.275 inches from the end of the barrel to the tip of the pad. Add your cable bend radius to that when you are checking clearance in a tight wireway or a shallow panel gutter.
7) Does the Blackburn ASL 350-48 TN meet spec for a commercial electrical submittal?
It is built to ANSI C119.4, the standard covering connectors for aluminum and copper conductors, and it is made in the United States. Those are the two lines most institutional and government submittals ask for on a feeder termination.
8) Is the ASL 350-48 TN sold individually or in a bag?
Sold each. Count one lug per conductor termination, so a three-phase plus neutral feeder run in 350 kcmil needs four, and order spares if you are crimping in the field where a bad crimp means scrapping the lug.
9) What is the exact part number to order this Blackburn stacking lug?
Blackburn ASL 350-48 TN. The ASL prefix is the aluminum stacking lug series, 350 is the conductor kcmil size, and TN denotes the tin plating.
