Blackburn CTL4-10 – Frequently Asked Questions
1) What wire size does the Blackburn CTL4-10 lug take?
The CTL4-10 is a 4 AWG copper compression lug. The 4 in the part number is the conductor size and the 10 is the stud size, so it terminates a single 4 AWG copper conductor onto a #10 stud or screw.
2) Can I use the Blackburn CTL4-10 on aluminum conductor?
No. The CTL4-10 is a copper-bodied lug intended for copper conductor only. For aluminum or dual-rated work you need an AL9CU-marked connector instead.
3) How many bolt holes does the CTL4-10 lug have, and can I use it on a two-hole pad?
One hole. The CTL4-10 is a single-hole (1HL) tongue lug, so it lands on a single #10 stud. If your bus or ground pad is drilled for two bolts on center, this one will not seat correctly and you want a two-hole lug.
4) Is the CTL4-10 lug rated for medium voltage terminations?
It carries a 35 kV voltage rating, which covers use inside medium voltage terminations and splices as well as ordinary 600 V panel and equipment work.
5) Is the Blackburn CTL4-10 UL listed?
Yes, it is covered under UL file E9809.
6) What does the short barrel on the CTL4-10 change for me?
The CTL4-10 is a short-barrel compression lug, so the crimp section is shorter than a standard long-barrel lug. That matters when you are terminating in a tight enclosure or a crowded gutter where there is not room for a long barrel behind the pad. It takes fewer crimps than a long barrel, so follow the die and crimp count marked on the barrel.
7) Is the CTL4-10 sold individually or in a box?
It sells each, so order one per termination. There is no minimum pack.
8) What does the grey color band on the CTL4-10 mean?
Grey is the die color code on this lug. The body is marked grey so an inspector or the next electrician can confirm the correct compression die was used for a 4 AWG copper termination.
