Blackburn 31015 – Frequently Asked Questions
1) What conductor sizes does the Blackburn 31015 lug accept?
The Blackburn 31015 is built for 300 through 500 kcmil conductors, which is the range printed on the lug itself. Anything smaller than 300 kcmil needs a different size in the Locktite range, since the barrel will not clamp a small conductor reliably even with the setscrew bottomed out.
2) Is the Blackburn 31015 a compression lug or a mechanical setscrew lug?
Mechanical, not compression. The 31015 is a setscrew Locktite connector, so it installs with a hex wrench and no crimp tool or die set. That matters on service work and in panels where you cannot get a hydraulic crimper onto the cable.
3) Can I use the Blackburn 31015 lug on aluminum conductor, or copper only?
Copper only. The 31015 is a CU lug, and the body material is copper. For aluminum or dual-rated work you need a lug marked AL9CU or AL/CU, not this one.
4) How many bolt holes does the Blackburn 31015 have, and will it land on a two-hole NEMA pad?
One hole. The 31015 is a single-hole lug, so it lands on a single stud or a one-bolt pad. If the equipment pad is drilled for a two-hole NEMA pattern with 1-3/4 inch center spacing, a one-hole lug will sit on it but only carry one bolt, which is usually not what the spec calls for. Use a two-hole lug in that case.
5) What is the manufacturer part number to order this Blackburn copper lug?
Blackburn 31015 is the part number, described as a Locktite copper one-hole lug for 300-500 kcmil. Quote it that way and there is no confusion with the aluminum-bodied or two-hole versions in the same family.
6) Is the Blackburn 31015 sold individually or in a box of multiples?
Sold each. Order the quantity of lugs you need, one per termination, so a three-phase plus neutral landing takes four.
7) Where is the Blackburn 31015 lug made? I need country of origin for a government job.
Manufactured in Mexico. That is the declared country of origin for the 31015, useful if you are filing origin documentation on a federally funded or institutional project.
