Blackburn CTL400L-58 – Frequently Asked Questions
1) What wire size does the Blackburn CTL400L-58 compression lug take?
The CTL400L-58 is sized for 400 kcmil copper conductor. It is a one hole, long barrel compression lug, so the conductor is crimped into the barrel rather than clamped by a set screw. Using it on a smaller conductor than 400 kcmil will not give you a proper crimp.
2) Is the Blackburn CTL400L-58 copper or aluminum?
Copper. It is a copper-bodied compression lug intended for copper conductor, not a dual-rated AL/CU connector. For aluminum conductor you want a connector specifically rated AL9CU or equivalent.
3) What does the blue color on this Blackburn lug mean?
Blue is the color code on the CTL400L-58 barrel, which identifies the die and crimp set for 400 kcmil copper. Match your crimp tool die to the color code stamped on the barrel rather than guessing by conductor size.
4) Why choose a long barrel lug instead of a standard barrel for a 400 kcmil feeder?
A long barrel takes two crimps instead of one, giving more contact length on the conductor and a higher pull-out resistance. That is the usual pick on large feeders and service entrance terminations where mechanical strain on the cable is a concern. A standard barrel is fine for shorter, supported runs where the extra crimp length is not needed.
5) Can I use this lug where a two hole connection is required?
No. The CTL400L-58 is a one hole lug. Where a spec or a grounding detail calls for a two hole tongue to prevent rotation, you need a two hole version rather than this one.
6) Is the Blackburn CTL400L-58 sold individually or in a bag?
Sold each. Order one per conductor termination, and remember a three phase plus neutral termination needs four.
