Blackburn CTL4002 – Frequently Asked Questions
1) What bolt size does this Blackburn lug land on, and how many holes?
Two-hole tongue with 1/2 inch stud holes. It lands on a 1/2 inch bolt pattern, which is the common bus and equipment pad drilling for conductors this size. A single-hole lug will not seat on a two-hole pad without leaving one bolt unused, so match the pad drilling before ordering.
2) Is the CTL4002 lug UL listed, and at what voltage?
It carries UL file E9809 and is rated 35 kV, so it can be used in medium voltage terminations as well as ordinary 600 V power work.
3) Can I use the CTL4002 copper lug on aluminum feeder cable?
No. This is a copper-bodied lug for copper conductors. Terminating aluminum in a copper-only lug is not a listed connection; for aluminum or dual-rated work you need an AL9CU marked compression lug in the matching 400 kcmil range.
4) What does the blue color on the Blackburn CTL4002 lug mean?
Blue is the die color code for the 400 kcmil copper compression range on this lug. Your crimp tool needs the matching blue die set to make a listed connection; using an off-color die is the most common reason a compression termination fails inspection.
5) Is this a compression lug or a mechanical set-screw lug?
The CTL4002 is a compression barrel lug, crimped onto the conductor with a hydraulic or battery crimper and the correct die. If you need a termination you can install with a hex key and re-torque later, you want a mechanical set-screw lug instead. Compression is the choice where a permanent, vibration-resistant connection is required.
6) Why choose a short barrel lug over a long barrel for a 400 kcmil termination?
A short barrel takes a single crimp and fits where space behind the pad is tight, such as crowded gutters, transformer throats, or switchgear compartments. A long barrel takes two crimps and gives more pull-out strength, which is preferred where the cable is under mechanical strain. The CTL4002 is the short barrel version.
7) Does the Blackburn CTL4002 come in a pack or as a single lug?
Sold individually, each. Order one per conductor termination, and remember a three-phase feeder with a neutral and ground needs five.
