Blackburn CTL20-38 – Frequently Asked Questions
1) What wire size does the Blackburn CTL20-38 lug take?
The CTL20-38 is sized for 2/0 AWG conductor. It is a one-hole, short barrel compression lug, so the barrel is crimped onto a single 2/0 cable. Running a different gauge means a different catalog number, not a different die setting.
2) Can I use this Blackburn lug on aluminum conductor?
No. The CTL20-38 is a copper compression lug and should be terminated on copper conductor only. For aluminum or dual-rated runs you need a lug marked AL9CU or an aluminum-bodied compression connector instead.
3) What is the difference between a short barrel lug like the CTL20-38 and a long barrel version?
A short barrel takes a single crimp and gives you a more compact termination, which matters when the gutter space or the distance between the cable entry and the stud is tight. A long barrel gives more crimp area and a longer grip on the conductor, and it is what you reach for on high-vibration or high-pull installations. The CTL20-38 is the short barrel, one-hole version for 2/0.
4) Does the Blackburn CTL20-38 come with the mounting bolt?
No. It sells as a bare lug, one each, and the 3/8 inch bolt, nut, and washers come from the equipment or are supplied separately. You will also need a compression tool with the correct die for the 2/0 copper barrel.
5) Why is this lug black instead of bare copper?
The CTL20-38 has a black finish over the copper body. It is a coating on a copper compression lug, not a different base metal, so it terminates copper conductor the same way a bare or tin-plated barrel would. Some contractors use the color to keep grounding or phase terminations visually sorted in a gear lineup.
6) Can I order a single CTL20-38 or do I have to buy a box?
The lug is sold individually, so you can buy the exact count a job needs rather than a full carton. Handy when you are replacing one or two terminations in existing gear.
