Blackburn CTL1-38 – Frequently Asked Questions
1) What wire size does the Blackburn CTL1-38 compression lug take?
The CTL1-38 is sized for 1 AWG conductor. It's a one-hole, short barrel compression lug in copper, so it goes on copper cable only, not aluminum. If your run is a different gauge, you need a different catalog number in the CTL family, since the barrel is crimped to one size and won't hold a smaller or larger conductor correctly.
2) Can I use the CTL1-38 on aluminum conductor?
No. This is a copper compression lug and it's rated for copper conductor only. Landing aluminum in a copper-only barrel risks a dissimilar-metal connection that loosens and heats over time. For aluminum or dual-rated work you need a lug marked AL9CU, not this one.
3) Is the CTL1-38 a compression lug or a mechanical set-screw lug?
Short barrel compression. The conductor is crimped in with a die tool, not clamped by a set screw, so you need the correct crimp die for a 1 AWG copper barrel to make the termination. A set-screw mechanical lug is the alternative if you don't have a crimper on site, but it's a different part number entirely.
4) How many bolt holes does the CTL1-38 have, and will one hole hold on a vibrating load?
One hole. A single-hole pad can rotate under vibration if the bolt backs off, so on motor terminations or generator connections a lot of specs call for a two-hole NEMA pad instead. For panel ground bars and static equipment grounds, one hole with a 3/8 inch bolt is the normal termination.
5) What's the exact part number to order for the Blackburn 1 AWG green grounding lug?
Blackburn CTL1-38. The CTL1 designates the 1 AWG copper compression lug body and the -38 designates the 3/8 inch stud hole, so the suffix is the piece that changes when you need a different bolt size.
6) Why is the CTL1-38 lug green, and does the color mean anything electrically?
The green finish on this Blackburn lug is a color identifier for grounding and bonding, matching the standard green identification used for equipment grounding conductors. It's an identification aid, not an insulator. The body itself is copper.
7) Does the CTL1-38 come in a pack, or is it sold one at a time?
It's sold each, so quantity is per lug. On a panel retrofit or a service ground upgrade, count one per conductor termination and order accordingly rather than assuming a bag of ten.
