Blackburn CTL1L-516 – Frequently Asked Questions
1) What wire size does the Blackburn CTL1L-516 lug take?
The CTL1L-516 is a one-hole copper compression lug sized for 1 AWG conductor. Ordered one lug at a time, so count your terminations, phases, neutral, and ground, before you buy.
2) Will the CTL1L-516 bolt to a 5/16 inch busbar stud?
Yes. The tongue is punched for a 5/16 inch stud, single hole, so it lands on a 5/16 bolt or stud at a panelboard, transformer, or ground bar. If your pad is drilled for 3/8, this lug will not seat correctly on it.
3) Is the CTL1L-516 a copper-only lug or can I use it on aluminum conductor?
It is a copper-bodied lug specified for copper conductor. For aluminum or dual-rated work you need a lug marked AL9CU; don't crimp aluminum into a copper-only barrel.
4) Is the Blackburn CTL1L-516 UL listed for service and grounding work?
It carries UL file E9809, which is the listing an inspector or spec writer will want to see on a compression connector. That covers the CTL1L-516 as supplied; installation still has to follow the listed die and tool.
5) What does the long barrel on this Blackburn lug do for me?
A long barrel gives room for two crimps instead of one, which is what many specs call for on power terminations and what inspectors look for on larger conductors. It also means a deeper conductor seat, so strip length has to match the barrel, not a short-barrel dimension.
6) Why is this Blackburn lug green, and does the color mean anything on the job?
Green is the die color code on this lug, and it tells you which die index to set in your crimp tool for a 1 AWG copper termination. Match the tool die to the color stamped on the barrel rather than guessing by conductor size.
7) Is the CTL1L-516 a mechanical set-screw lug or a compression lug?
Compression. There is no set screw on it, so you need a hydraulic or battery crimper with the correct die. If you want to terminate 1 AWG without a crimp tool, look for a mechanical set-screw lug instead, but note that many specs on feeder terminations call out compression.
8) How do I order the exact Blackburn part number for a 1 AWG, 5/16 stud copper lug?
Order Blackburn CTL1L-516. The number reads across as one-hole copper long barrel, 1 AWG, 5/16 inch bolt hole. It ships as single pieces, made in Mexico.
