Blackburn CTL10-12 – Frequently Asked Questions
1) What wire size does the Blackburn CTL10-12 lug take?
The CTL10-12 compression lug is sized for 1/0 AWG conductor. It's a copper barrel lug, so it terminates copper cable of that size. If your feeder is a different gauge, you need the matching lug in the series, not this one, since a compression barrel only crimps correctly on the conductor it's die-sized for.
2) Will the CTL10-12 lug bolt to a 1/2 inch bus stud?
Yes. The lug has a single hole sized for a 1/2 inch stud or bolt. It's a one-hole tongue, so it lands on a single bus or breaker pad bolt rather than a two-hole pattern. If your bus is drilled for two holes on NEMA spacing, this isn't the right tongue configuration.
3) Can I use the CTL10-12 copper lug on aluminum cable?
No. This is a copper-bodied lug rated for copper conductor at 1/0 AWG. Terminating aluminum in a copper-only connector risks galvanic corrosion at the joint. For aluminum feeders, use a dual-rated AL9CU compression lug in the same size instead.
4) Do I need a crimper for the Blackburn CTL10-12, or can I torque it down?
It's a compression lug, not a mechanical set-screw lug, so it has to be crimped with a hydraulic or battery compression tool using the die that matches the pink code. Nothing about the barrel accepts a set screw. If you want a wrench-only termination on 1/0 AWG, you need a mechanical set-screw lug instead.
5) Why is the Blackburn CTL10-12 lug pink?
Pink is the color code that tells an inspector and the next electrician which compression die was used. On this 1/0 AWG copper lug, the pink band identifies the die index for the crimp, so the finished termination can be verified by color instead of taking it apart. Match the die color on your crimping tool to the band on the barrel.
6) What does short barrel mean on this Blackburn lug, and when does it matter?
Short barrel means a single crimp length rather than a long two-crimp body. It matters when you're working in a tight gutter or a crowded panel where there isn't room behind the pad for a long barrel. The trade-off is one crimp instead of two, so the die has to be right, which is what the pink color code on the CTL10-12 confirms.
7) What is the exact part number to order this Blackburn 1/0 one-hole lug?
Blackburn CTL10-12. That designation covers the copper one-hole short-barrel compression lug for 1/0 AWG with a 1/2 inch stud hole. Adjacent numbers in the series change either the conductor size or the bolt hole, so the full suffix matters when you're ordering.
8) Is the CTL10-12 sold individually or in a bag?
Sold each. One lug per unit, so order the exact count your terminations require rather than buying a carton quantity you don't need.
9) Where is the Blackburn CTL10-12 made?
Manufactured in Mexico. That's the country of origin to cite on submittal paperwork or a government job requiring origin disclosure.
