Blackburn CTL4L-14 – Frequently Asked Questions
1) What wire size does the Blackburn CTL4L-14 lug take?
The CTL4L-14 is a one-hole copper compression lug sized for 4 AWG conductor. It is a single-conductor barrel, so one 4 AWG cable per lug. If your feeder is a different gauge, you need a different catalog number in the series; a 4 AWG barrel will not crimp reliably on anything else.
2) Will the Blackburn CTL4L-14 bolt to a 1/4 inch stud on my panel bus?
Yes. The CTL4L-14 has a single bolt hole sized for a 1/4 inch stud. One hole means it can rotate on the stud under torque, so if your equipment pad is drilled for two-hole NEMA spacing, this is the wrong lug for that pad.
3) Is this Blackburn lug copper only, or can I land aluminum conductor in it?
Copper only. The CTL4L-14 barrel is copper, which makes it a CU-rated terminal for copper conductor. For aluminum or dual-rated AL9CU work you need a different lug body.
4) What does the long barrel on the CTL4L-14 lug do for me?
The long barrel gives room for two crimps instead of one, which is what you want on vibration-prone or higher-pull terminations such as motor leads and switchgear feeders. A standard short-barrel lug takes a single crimp in the same 4 AWG size.
5) What does the grey color code on this Blackburn lug mean?
Grey is the die color code on the CTL4L-14, matching the crimp die and index used to compress a 4 AWG copper barrel. Match the grey die in your hydraulic or battery tool to the lug rather than judging by eye.
6) Does the CTL4L-14 come in a bag or is it sold one at a time?
Sold each, one lug per unit. Count your terminations, including the neutral and ground landings, and order that many.
