Blackburn ATL40-12 – Frequently Asked Questions

1) Will the Blackburn ATL40-12 lug work on 4/0 AWG aluminum cable?
That is exactly what it is built for. The ATL40-12 is a compression lug sized for 4/0 AWG aluminum conductor, so the barrel is matched to that one conductor size. It is not a range connector, so a 2/0 or 250 kcmil run needs a different part number. One conductor, one barrel, crimped with the die called for by the lug.
2) Can I use this aluminum compression lug on copper conductor?
The ATL40-12 is an aluminum-bodied compression lug specified for 4/0 AWG aluminum cable. If your feeder is copper, buy a lug rated for copper (or a dual-rated AL9CU connector) instead. Terminating copper in a connector listed for aluminum only is not a code-compliant termination.
3) Do I need a crimp tool for this lug, or does it bolt on mechanically?
This is a compression lug, not a set-screw mechanical connector. The conductor is crimped into the barrel with a hydraulic or battery compression tool and the correct die, then the tongue bolts to the stud. If you want a connector you can install with a hex key and no press, you need a mechanical lug instead.
4) What does the white color on the Blackburn ATL40-12 lug mean?
White here is the finish on the lug body. Crews on multi-lug jobs use the color to phase-mark or color-code terminations at the panel so the right conductor lands on the right stud during troubleshooting. It has no bearing on the electrical rating or on which conductor size the barrel accepts.
5) How is the Blackburn ATL40-12 sold, per piece or in a bag?
Each. A lug is sold as a single piece, so count your terminations, including neutrals and grounds, and order one per conductor landing. Large panel and motor feeder jobs commonly need several at a time.
6) Where is the Blackburn ATL40-12 lug made?
Mexico. Buyers working government, utility, or institutional contracts with sourcing clauses usually need the country of origin on record before release, so it is worth noting on the submittal.
