Blackburn CTL1000L-58 – Frequently Asked Questions
1) What conductor size does the Blackburn CTL1000L-58 compression lug take?
The CTL1000L-58 is sized for 1000 kcmil copper conductor, which is what the "1000" in the catalog number refers to. It is a copper compression lug, so it goes on copper cable only, not aluminum.
2) Will this Blackburn lug bolt to a 5/8 inch stud or bus bolt pattern?
Yes. The CTL1000L-58 has 5/8 inch bolt holes, so it lands on 5/8 inch studs or 5/8 inch hardware through a bus bar. It is a two-hole pad, so both holes have to line up with your bus pattern, and a single-hole lug will not substitute if the pad spacing is what you are matching.
3) Is this Blackburn 1000 kcmil lug rated for medium voltage terminations?
It carries a 35 kV voltage rating, which puts it in medium-voltage service, and it is UL listed under file E9809. On a 35 kV termination the lug is only part of the system, you still need the stress cone or termination kit and the correct insulating treatment for the splice.
4) Do I need a crimp tool for this, or does it set with bolts?
This is a compression lug, not a mechanical set-screw connector, so the barrel is crimped onto the conductor with a hydraulic compression tool and the die that matches a 1000 kcmil copper barrel. If you want a connector you can install with a wrench, you need a mechanical lug instead.
5) Is the CTL1000L-58 a long barrel or short barrel lug?
The catalog description reads short barrel for the CTL1000L-58. Barrel length matters because a long barrel takes two crimps and gives more pullout resistance, while a short barrel is used where there isn't depth in the enclosure. Follow the crimp count the die chart calls for on this barrel.
6) Is this copper lug OK to land on an aluminum bus bar?
The lug body is copper, so bolting it directly to aluminum bus puts dissimilar metals in contact. Use a bimetallic washer or a tin-plated interface and the appropriate joint compound at that connection, or specify an aluminum-bodied lug instead.
7) How is this lug sold, in packs or individually?
Sold each, so a two-hole 1000 kcmil termination is one piece per conductor. Count one lug per cable end, plus spares if you are compressing in the field where a bad crimp means scrapping the lug.
8) Where is the Blackburn CTL1000L-58 made? I need country of origin for a government job.
Country of origin is Mexico. For federal or institutional procurement with domestic-content language, that is the figure to put on your submittal.
