Blackburn CTL30L-12 – Frequently Asked Questions
1) What wire size and stud size does the Blackburn CTL30L-12 compression lug take?
The CTL30L-12 is sized for 3/0 AWG conductor and lands on a 1/2 inch stud or bolt. Use it only on 3/0 cable, compression lugs are single-size barrels and a smaller conductor in a 3/0 barrel will not crimp to a reliable connection.
2) Is the Blackburn CTL30L-12 lug copper or aluminum, and can I use it on aluminum conductor?
It's a copper-bodied lug. Use it on copper conductor. For aluminum or dual-rated runs you want an AL9CU-rated connector instead.
3) Why is the Blackburn CTL30L-12 lug orange, and what does the color mean on a compression lug?
Orange is the die color code for this barrel. On copper compression lugs, the color identifies which crimp die index to set your tool to, so the orange marking tells the installer the tool setting that matches the 3/0 barrel. Match the die to the color, not to the cable size printed on the jacket.
4) How many bolt holes does the Blackburn CTL30L-12 lug have?
One hole, sized for a 1/2 inch stud. A single-hole lug can rotate under torque, so if your pad is drilled for two holes on centers, or the application calls for anti-rotation, specify a two-hole lug instead.
5) What is a long barrel lug and when should I use one instead of a standard barrel?
A long barrel takes two crimps rather than one, which gives more contact length on the conductor and better pull-out resistance. Electricians specify long barrel on 3/0 and larger feeders, generator and switchgear terminations, and anywhere the connection sees vibration or high fault current. Standard barrel is fine for lighter, static terminations.
6) Does the Blackburn CTL30L-12 come as a single lug or in a pack?
Sold individually, one lug per unit. For a three-phase plus neutral termination order four, and count both ends of the run if you're lugging cable at each end.
7) Where is the Blackburn CTL30L-12 lug made?
Manufactured in Mexico. Relevant if you're submitting on a job with country-of-origin reporting or domestic-preference language in the specification.
