Blackburn CTL2502 – Frequently Asked Questions
1) What bolt size does the CTL2502 lug pad drill out to?
Stud size is 1/2 inch, so the tongue is drilled for 1/2 inch hardware, and it is a two-hole tongue. Two-hole pads resist rotation under torque and are what most switchgear and busbar landings are drilled for, so confirm your pad hole spacing before you crimp.
2) Can I use the CTL2502 lug on medium voltage cable terminations?
Yes. The CTL2502 carries a 35 kV rating, which covers 5 kV, 15 kV, 25 kV and 35 kV class shielded cable terminations as well as ordinary 600 V work.
3) Will this Blackburn lug work on 250 kcmil aluminum conductor?
No. This is a copper-bodied lug sized for copper conductor. Terminating aluminum in a copper-only barrel is not an approved combination; use a dual-rated AL9CU or aluminum-specific compression lug for aluminum cable.
4) Is the Blackburn CTL2502 a crimp lug or a mechanical set-screw lug?
It is a compression (crimp) lug with a short barrel, so it is installed with a hydraulic or battery crimp tool and the correct die, not tightened with a set screw. If you need a reusable connection you can loosen in the field, use a mechanical lug instead.
5) What does the yellow color code on this 250 kcmil Blackburn lug mean?
Yellow is the die color code for this barrel. Match the yellow index on your crimp tool die set to the yellow marking on the lug so the crimp is made to the rated compression. The color is not a voltage or insulation indicator.
6) Is the CTL2502 sold individually or in a bag of lugs?
It is sold each, one lug per unit, so order one per cable end you are terminating. Remember a two-hole tongue needs two 1/2 inch bolts, nuts and washers per lug, and none of that hardware is part of the lug.
7) Where is the Blackburn CTL2502 lug made?
Country of origin is Mexico. That is the detail a government or institutional buyer needs for domestic-preference or trade-compliance paperwork on a submittal.
