Blackburn CTL20-12 – Frequently Asked Questions
1) What wire size does the Blackburn CTL20-12 lug take?
The CTL20-12 is a one hole compression lug sized for 2/0 AWG conductor. It is a single-conductor barrel, so one 2/0 cable per lug. If your feeder is a different gauge, step to the matching part in the CTL range rather than crimping an undersized or oversized conductor into this barrel.
2) Will the CTL20-12 lug bolt to a 1/2 inch stud on my panelboard?
Yes. The tongue on the CTL20-12 is drilled for a 1/2 inch stud or bolt, single hole. That is the common bus and breaker pad size on larger commercial panels and switchgear, so it lands directly on a 1/2 inch landing pad without a washer stack or adapter.
3) Is this Blackburn lug copper or aluminum, and can I use it on aluminum conductor?
The CTL20-12 barrel is copper, so it is intended for copper conductor. It is not a dual-rated AL/CU compression lug. If you are terminating aluminum feeder, choose an AL9CU or dual-rated lug instead, because a copper-only barrel with aluminum cable risks a dissimilar-metal connection.
4) What does short barrel mean on the CTL20-12, and when would I want the long barrel version instead?
Short barrel means a single crimp length barrel, which is what you want in tight gutters and shallow panel wireways where there is not room to swing a crimp tool twice. A long barrel takes two crimps and is normally specified where higher pull-out resistance is called for. The CTL20-12 is the short barrel, one hole, 2/0 version.
5) Does the CTL20-12 lug come as a single piece or in a bag, and does it include the mounting bolt?
It sells each, one lug per unit, so order a piece for every conductor you are landing. Mounting hardware is not part of the lug; the bolt, nut and washers for the 1/2 inch stud come from the equipment or are bought separately. Crimp dies suited to a 2/0 copper compression barrel are also needed.
6) Is this a compression lug or a set screw mechanical lug?
The CTL20-12 is a cable or wire compression lug with a plain barrel, so it is crimped onto the conductor with a die tool. There is no set screw. If you need a termination that can be installed with hand tools only and re-opened later, a mechanical set screw lug is the type to use instead.
7) Where is the Blackburn CTL20-12 lug made, for submittal paperwork?
Country of origin on the CTL20-12 is Mexico. That is the value to put on a submittal or domestic-content declaration for this part.
8) Why is the Blackburn CTL20-12 black, and does the coating matter for the connection?
The lug is finished black, which is a Blackburn identification and coating convention on their copper compression range. The crimp barrel and the bolt face still make a copper-to-copper connection, so the color has no bearing on how it lands on the pad.
