Blackburn ATL300-12 – Frequently Asked Questions
1) What wire size does the Blackburn ATL300-12 compression lug take?
The ATL300-12 is sized for 300 kcmil conductor, which is what the 300 in the part number designates. It's a one-hole aluminum compression lug, so the barrel is crimped onto the conductor rather than set-screwed, and the die/color code for this size is blue. Wrong conductor size means a crimp that won't hold, so match the 300 kcmil call-out and the blue code before you crimp.
2) Can I use this aluminum lug on copper conductor, or is it aluminum only?
The ATL300-12 body is aluminum and it is rated for both aluminum and copper conductor, which is what the TP (tin-plated, dual rated) designation in the description covers. Tin plating on the aluminum barrel is what makes the copper connection acceptable without a galvanic problem at the crimp.
3) What voltage is the Blackburn ATL300-12 lug rated for?
35 kV. That puts it in medium-voltage territory, so it's usable on 15 kV and 25 kV class terminations as well as 600 V work. The rating covers the lug itself, not the insulation system around it, so your splice or termination kit still has to carry the class rating for the circuit.
4) Do I need a crimp tool for this lug, or can I tighten it with a set screw?
This is a compression lug, not a mechanical set-screw connector, so it has to be crimped with a hydraulic or battery crimper and the die matching the blue 300 kcmil code. If you want a connection you can make with a hex key and no tooling, you need a mechanical set-screw lug instead.
5) Does the ATL300-12 come as a single lug or in a bag of multiples?
Sold each. Order one per conductor termination, so a three-phase-plus-neutral feeder pull needs four, plus whatever you want on hand for a bad crimp.
6) What is the exact part number and origin for the Blackburn 300 kcmil one-hole lug?
Blackburn ATL300-12, made in Mexico. Distributors cross-referencing spec packages should quote it as ATL300-12: the ATL prefix is the aluminum tin-plated compression body, 300 the kcmil size, and -12 the 1/2 inch stud hole.
