Blackburn CTL8-516 – Frequently Asked Questions
1) What wire size does the Blackburn CTL8-516 compression lug take?
The CTL8-516 is sized for 8 AWG conductor, one hole, short barrel. Run anything larger or smaller through it and you won't get a proper crimp, so match the conductor exactly to 8 AWG.
2) Is the CTL8-516 lug copper or aluminum, and can I use it on aluminum conductor?
It's a copper lug, so use it on copper conductor only. For aluminum or for a dual-rated run you want an AL9CU-rated connector instead, not this one.
3) What does the red color on this Blackburn compression lug mean?
Red is the die color code for the 8 AWG compression range on this lug. It tells the installer which die set and crimp position to use, and it's a quick visual check on a panel that the right size terminal went on the right conductor.
4) Short barrel or long barrel lug for a crowded panel?
The CTL8-516 is a short barrel, one-crimp terminal. Short barrel is what you want where the gutter space is tight or the conductor lands close to the stud. A long barrel takes two crimps and gives more pullout resistance on vibrating or high-strain runs, so pick that instead where the connection is mechanically loaded.
5) Can I use the Blackburn CTL8-516 as a grounding lug on a ground bar?
It's a copper cable/wire lug for 8 AWG on a 5/16 stud, which is the common grounding-electrode and equipment-ground termination in commercial panels. As long as your ground bar or busbar takes a 5/16 bolt and the conductor is 8 AWG copper, it lands.
6) Does the CTL8-516 lug come in a bag or singly?
It's sold each, so you order the exact count the job needs rather than a fixed bag quantity.
