Blackburn ATL350-12 – Frequently Asked Questions
1) What wire size does the Blackburn ATL350-12 lug take?
The ATL350-12 is sized for 350 kcmil conductor. It's a compression (crimp) lug, so the barrel is made for one 350 kcmil cable and nothing else. If your feeder is 250 or 400 kcmil, you need the matching lug in that size, not this one.
2) Will this lug bolt to a 1/2 inch stud on my panel bus?
Yes. The ATL350-12 is a one-hole lug with a 1/2 inch stud size, so it lands on a 1/2 inch bolt or stud. It's a single bolt hole, not two, so on a two-hole NEMA pad you'd want a two-hole lug instead to keep the termination from rotating.
3) Can I use an aluminum compression lug on copper conductor?
The ATL350-12 barrel is aluminum. Blackburn AL-series compression lugs of this type are dual-rated for aluminum or copper 350 kcmil conductor, and they ship pre-filled with oxide-inhibiting compound for the aluminum connection. Confirm the AL9CU marking stamped on the barrel before you crimp copper into it.
4) What does the brown color on this Blackburn lug mean?
Brown is the die color code for the crimp. The ATL350-12 is color-coded brown, so you set your compression tool to the brown die index for that barrel. Match the die to the color on the lug, not to the wire size, and you get the correct number of crimps and a conforming termination.
5) Should I use a compression lug or a mechanical set-screw lug for a 350 kcmil feeder?
A compression lug like the ATL350-12 is crimped on with a hydraulic or battery tool and the joint is permanent, so there's nothing to re-torque later. A mechanical set-screw lug installs with a hex key and no special tool, and it can be removed and reused. For gear that gets inspected on a maintenance cycle, crews often prefer compression because there is no torque value to check; for a one-off field termination with no crimper on the truck, go mechanical.
6) Does the ATL350-12 come in a bag or is it sold individually?
Sold each. One lug per unit, so for a three-phase-plus-neutral termination you order four, plus a spare if you want one on the truck. There's no multi-pack bundling on the part.
7) Where is the Blackburn ATL350-12 made?
Country of origin is Mexico. That matters on projects with domestic-preference or trade-agreement language in the spec, so check it against your submittal requirements before the package goes in.
