Blackburn ATL500-12 – Frequently Asked Questions
1) What wire size does the Blackburn ATL500-12 compression lug take?
The ATL500-12 is sized for 500 kcmil conductor, which is what the "500" in the catalog number refers to. It's a one-hole aluminum compression lug, so the barrel is crimped onto the conductor rather than screwed down. Ordering is by the each.
2) What bolt size does the tongue on the Blackburn ATL500-12 land on?
One bolt hole, and the stud size is 1/2 inch, so it lands on a 1/2 inch bolt or stud at the pad, bus, or lug landing. The 5/16 in the catalog description refers to the hole detail on the tongue, so match the pad hardware to a 1/2 inch stud when laying out the termination.
3) Can I use this aluminum lug on a copper conductor, or is it aluminum only?
Blackburn's ATL500-12 barrel is aluminum, and the pink color code identifies the die/crimp size on installation. Aluminum compression barrels of this type are dual rated for aluminum or copper only when the part is marked AL9CU; if your run is copper, verify that marking on the barrel before crimping rather than assuming it from the aluminum body.
4) Is the Blackburn ATL500-12 UL listed for an inspected commercial job?
It's covered under UL file E9809. For an electrical inspector or an institutional spec that requires listed terminations, that file reference is the record to cite along with the 35 kV rating.
5) What does the pink marking on this Blackburn compression lug mean?
Pink is the color code on the barrel that tells the installer which crimp die and number of crimps to use. Match the die color on your hydraulic or battery crimper to the pink band rather than guessing by conductor size, since a mismatched die is the usual cause of a failed pull test on a 500 kcmil termination.
6) Should I use a compression lug like this or a mechanical set screw lug?
A compression lug such as the ATL500-12 is crimped permanently onto the conductor with a die tool, which gives a termination that doesn't need re-torquing and is standard where vibration or a medium voltage rating matters (this one is rated 35 kV). A mechanical set screw lug installs with nothing but a hex key and can be removed and reused, which suits a service change or a panel where you expect to re-terminate. If you don't have a crimper with the right die on site, the mechanical style is the practical choice.
7) How is the Blackburn ATL500-12 packaged and ordered?
Sold individually, one lug per unit, so you can order the exact count for the number of terminations on the job instead of a fixed carton. The part number to order against is ATL500-12, made in Mexico.
