Blackburn CTL2L-516 – Frequently Asked Questions
1) What wire size does the Blackburn CTL2L-516 lug take?
The CTL2L-516 is built for 2 AWG conductor. It's a single-hole, long barrel compression lug in copper, so it goes on 2 AWG copper cable and gets crimped, not bolted or set-screwed. If your conductor is a different size, you need a different catalog number in the series; a compression lug only makes a proper termination on the conductor it's rated for.
2) Can I put aluminum conductor in the CTL2L-516?
No. This one is copper-bodied and rated for copper conductor only. For aluminum or dual-rated work you need an AL9CU marked connector instead. Using a copper-only lug on aluminum is a code violation and a failure point.
3) What does the brown color band on this Blackburn compression lug mean?
Brown is the die color code on the CTL2L-516. When you crimp it you set your compression tool to the matching brown die for that barrel, which is how an inspector confirms the right die was used on the right size lug. It's a color identifier, not a finish.
4) Why choose a long barrel lug instead of a standard barrel one?
The long barrel on the CTL2L-516 gives you room for two crimps instead of one, which is what you want on high-vibration equipment, switchgear, or anywhere the spec calls for a double-crimp termination. A standard short barrel takes a single crimp and is fine for general panel work. Same conductor size, same 5/16 inch stud hole, just more barrel length to compress.
5) Is the CTL2L-516 sold individually or in a bag of multiples?
Sold each, so order the exact count you need. On a three-phase feeder plus neutral and ground you're typically buying five per termination point, so count both ends of the run.
6) What is the exact part number and where is this Blackburn lug made?
Blackburn model CTL2L-516, manufactured in Mexico. That's the number to quote for a match on a 2 AWG copper, 5/16 inch stud, one-hole long barrel compression lug.
