Blackburn CTL30-38 – Frequently Asked Questions
1) What wire size does the Blackburn CTL30-38 compression lug take?
The CTL30-38 is sized for 3/0 AWG copper conductor, one hole, short barrel. It is a copper compression lug, so it goes on 3/0 copper cable only, not aluminum and not a different gauge. If your conductor is a different size, you need the matching size code in the CTL series instead, because a crimp lug only makes a proper connection on the conductor it was die-sized for.
2) Can I use this copper lug on aluminum conductor?
No. The CTL30-38 is a copper-only compression lug. Aluminum conductor needs a connector rated AL9CU or an aluminum-bodied lug with the appropriate inhibitor compound, otherwise you get a dissimilar metal joint that degrades. Use a dual-rated connector for aluminum feeders.
3) What does the orange color on the Blackburn CTL30-38 lug mean?
Orange is the color code on this lug, and on copper compression connectors the color identifies the crimp die and die index for the barrel, so the installer matches the tool die to the connector rather than guessing. Crimp it with the die that corresponds to the orange code for 3/0 copper.
4) Is this a compression lug or a mechanical set screw lug?
It is a compression (crimp) barrel lug, cataloged as a standard barrel cable or wire lug, so it needs a hydraulic or battery crimper with the correct die. If you want a connection you can make with a hex key and no crimp tool, you want a mechanical set screw lug instead. Compression is generally preferred where vibration or thermal cycling is a concern, since there is no screw to re-torque.
5) Is the Blackburn CTL30-38 UL listed?
It carries UL file E9809. That is the reference an inspector or spec writer will want for a terminated conductor on a listed installation.
6) Why is it called a short barrel lug, and does that matter for my install?
Short barrel means the crimp sleeve is shorter than a long barrel version of the same 3/0 copper lug, which is what you want in a tight gutter, a crowded panel, or where the conductor bends up close to the landing pad. A long barrel takes more crimps and gives more contact length, so use that where you have the room and the spec calls for it.
