Blackburn CTL300L-12 – Frequently Asked Questions
1) What cable size does the Blackburn CTL300L-12 lug accept?
The CTL300L-12 is sized for 300 kcmil conductor. It's a one-hole, long barrel compression lug, so the barrel is crimped onto the cable rather than set-screwed. Run it only on 300 kcmil; a smaller conductor won't crimp reliably in that barrel.
2) What does the white color code on this Blackburn lug mean?
White is the die color code for this connector, and it's how a crimp gets verified in the field: the installer matches the white code on the lug to the white die/index on the compression tool so the inspector can confirm the right die was used on the 300 kcmil barrel.
3) Why choose a long barrel lug instead of a standard barrel for a 300 kcmil feeder?
A long barrel takes two crimps instead of one, which is what most specs call for on high-current feeder terminations and on runs subject to vibration or pull-out. The CTL300L-12 is the long barrel version at 300 kcmil with a 1/2 inch bolt hole. If the spec only asks for a single crimp and space in the gutter is tight, a short barrel lug is easier to fit.
4) Is the CTL300L-12 sold individually or in a pack?
Sold each, by the single lug. Count your terminations, including neutrals and grounds, and order that quantity, since a three phase plus neutral landing at both ends needs eight.
