Blackburn CTL20L-38 – Frequently Asked Questions
1) What wire size does the Blackburn CTL20L-38 compression lug take?
The CTL20L-38 is sized for 2/0 AWG copper conductor. It is a one hole, long barrel compression lug, so it is crimped onto the cable rather than set screw clamped. Match the die to 2/0 copper when you crimp it; a 2/0 lug will not hold 4/0 or #2 correctly.
2) Can I use the CTL20L-38 on aluminum conductor?
No. This lug is copper, specified for copper cable. Aluminum feeders need an AL9CU rated or aluminum bodied connector with the correct oxide inhibitor; putting bare aluminum into a copper only barrel risks a bad termination.
3) Why choose a long barrel lug over a standard barrel for a 2/0 feeder?
A long barrel takes two crimps instead of one, giving more contact length on the conductor and better pull out resistance. Electricians and inspectors on service and switchgear work often call for long barrel on larger feeders like 2/0. The trade off is that you need enough room behind the stud for the extra barrel length.
4) Is the Blackburn CTL20L-38 a UL listed connector?
It carries UL file E9809. That is the reference a plant or institutional inspector will want on a compression connector used in a listed assembly.
5) Is the black coating on this lug an insulator?
The CTL20L-38 is a black finished copper compression lug. It is not an insulated or heat shrink covered terminal, so where you need insulation at the barrel, add adhesive lined shrink over the crimp after termination.
6) Does this Blackburn lug come in a bag or is it sold individually?
The CTL20L-38 is sold each, so you buy exactly the count you need for the terminations on the job rather than a fixed carton.
