Blackburn 32007 – Frequently Asked Questions
1) What wire size does the Blackburn 32007 two-hole lug accept?
The Blackburn 32007 is a Locktite compression-free mechanical lug rated for conductors in the 4 AWG through 1 AWG range, which is what the "4-1" in the part description refers to. It is sold individually, one lug per order.
2) Do I need a crimping tool or hydraulic press to install the Blackburn 32007 lug?
No press or die set needed. The 32007 is a mechanical connector, so it lands the conductor with set screws and installs with a hand tool. That is the practical reason electricians and maintenance crews reach for it over a compression lug on service and panel work where a hydraulic crimper isn't on the truck.
3) Is the Blackburn 32007 lug UL listed?
It carries UL file E9809. For inspectors and institutional specs that call for a listed terminator, that file number is the one to cite on the 32007.
4) Can I use the Blackburn 32007 on aluminum conductors?
The 32007 is a copper-bodied lug built for copper conductors. If your feeder is aluminum or you are landing AL on a CU bus, you want a dual-rated AL9CU connector instead, not this one.
5) Why choose a two-hole lug over a single-hole lug on a ground bus or equipment pad?
Two-hole lugs like the 32007 land on two bolts, so the conductor can't rotate under fault current or vibration. That is why grounding and bonding details on switchgear, generator pads, and transformer connections routinely call for a two-hole pattern rather than a single bolt.
6) Is the Blackburn 32007 the same part as a NSI or Burndy two-hole mechanical lug?
Not interchangeable by part number. The 32007 is a Blackburn Locktite lug; order it by that number. Cross-referencing to another manufacturer's two-hole lug means matching the 4-1 AWG conductor range, the copper-only rating, and the bolt hole spacing and stud size on your bus, since those vary between makers.
7) What is the country of origin on the Blackburn 32007 lug for a Buy American or submittal package?
The 32007 is manufactured in Mexico. Government and institutional procurement packages that require domestic sourcing should note that before specifying it.
