Blackburn ATL30-12 – Frequently Asked Questions
1) What wire size does the Blackburn ATL30-12 compression lug take?
The ATL30-12 is sized for 3/0 AWG conductor. It is a one-hole aluminum compression lug, so the barrel is crimped onto the cable rather than set-screwed. Using it on a conductor other than 3/0 AWG will not give you a proper compression, so match the cable before you crimp.
2) Can I use an aluminum compression lug on copper conductor?
The ATL30-12 body is aluminum, and Blackburn's aluminum compression connectors of this type are dual rated for copper or aluminum conductor. The lug itself is the same either way; what changes is the die and, on aluminum cable, the need to wire brush and use an inhibitor compound at the joint.
3) What does the ruby color on this Blackburn lug mean?
Ruby is the color code on the ATL30-12, and on compression connectors that color identifies which die and die index to crimp with. Match your crimp tool's ruby die to the barrel rather than guessing by cable size, and confirm the die index stamped on the barrel before you make the crimp.
4) Should I use a compression lug or a mechanical set-screw lug for a 3/0 feeder?
A compression lug like the ATL30-12 needs a hydraulic or battery crimper and the correct ruby die, but once crimped it needs no re-torque and cannot loosen with thermal cycling, which is why specs on switchgear and service equipment often call for it. A mechanical set-screw lug installs with a hex key and no special tooling and can be reused, at the cost of periodic torque checks. For a permanent 3/0 feeder termination in a panel or on a bus, the compression version is the one most drawings ask for.
5) Is this lug sold individually or in a bag of ten?
The ATL30-12 sells each, one lug per unit. Count your terminations, including neutrals and grounds, and order the quantity you need; nothing is bundled into a kit here.
6) What is the exact part number and country of origin for this Blackburn lug?
Order it as Blackburn ATL30-12. It is manufactured in Mexico, which matters if you are filing origin documentation on a public or federally funded project.
