Blackburn ATL40-38 – Frequently Asked Questions
1) What wire size does the Blackburn ATL40-38 compression lug take?
The ATL40-38 is sized for 4/0 AWG cable. It is a one-hole aluminum compression lug, so it is crimped onto the conductor with a die-type compression tool rather than tightened with a set screw. Pick the barrel to match the conductor exactly, 4/0 AWG here, since a compression barrel has no range-taking ability.
2) Will a 3/8 inch bolt fit the pad on the Blackburn ATL40-38 lug?
Yes. The tongue is drilled for a 3/8 inch stud, which is the common bus and breaker pad size on panelboards, switchboards and transformer terminals. It is a single-hole tongue, so if your bus is drilled for two-hole NEMA spacing you need a two-hole lug instead.
3) What does the white color on the Blackburn ATL40-38 lug mean?
White is the die color code for this compression lug. Blackburn color codes compression connectors so an inspector can confirm from across the vault that the correct die index was used on the crimp. Match the tool die to the white code called out on the barrel, and keep the crimp count per the die instructions.
4) Is the Blackburn ATL40-38 UL listed for use on a service or panel termination?
It carries a UL listing under file E9809, which is what an inspector or spec writer looks for on a terminating connector. That listing is the basis for using it as a UL recognized wire termination on 4/0 aluminum with a 3/8 inch bolted pad.
5) Do I need a set screw wrench or a crimper for the Blackburn ATL40-38?
A crimper. This is a compression lug, not a mechanical set screw lug, so you need a hydraulic or battery compression tool with the matching die. If your crew only carries hex keys, a mechanical aluminum body lug rated for 4/0 with a 3/8 inch hole is the easier call on the job.
6) Is the ATL40-38 sold individually or in a bag of ten?
Sold each. Count your terminations, one lug per conductor end, and remember a three phase plus neutral feeder in 4/0 aluminum needs four at each end.
7) Where is the Blackburn ATL40-38 lug made?
Mexico. That is the detail a government or institutional buyer needs when a purchase order carries country of origin or trade compliance reporting on it.
