Blackburn 32207 – Frequently Asked Questions
1) What conductor size does the Blackburn 32207 two-hole lug take?
The Blackburn 32207 is a two-hole compression-free mechanical lug built for copper conductors in the 4 AWG through 1 AWG range, which is what the "4-1" in the part description refers to. Because it's a mechanical Locktite-style connector, the conductor is secured with set screws rather than a crimp tool, so no die set or hydraulic crimper is needed to land the cable.
2) Can I use the Blackburn 32207 lug on aluminum wire?
No. The 32207 is a copper-bodied lug rated for copper conductors only (CU). For aluminum or dual-rated runs you need an AL9CU marked connector instead. Landing aluminum in a copper-only lug is a code and galvanic corrosion problem, so match the marking to the conductor.
3) Will the Blackburn 32207 bolt to a standard NEMA ground bar or bus pad?
Yes. It's a two-hole NEMA pattern lug, so the mounting holes follow the standard NEMA spacing used on switchgear pads, bus bars, and ground bars. The two-hole pattern also keeps the lug from rotating under torque, which is why specs often call for two-hole over single-hole on equipment grounding and bonding terminations.
4) Do I need a crimping tool for the Blackburn 32207, or is it a mechanical lug?
Mechanical. The 32207 is a Locktite-type set screw connector, so a hex key or torque wrench is all that's needed on the conductor side plus the bolts, nuts, and washers for the pad. Compression lugs in the same size range need a matched die and hydraulic head, which is the trade-off if you're deciding between the two on a job.
5) Is the Blackburn 32207 sold individually or in a bag of multiples?
Each. The 32207 is sold as a single lug, so if you're terminating both ends of a run or landing several feeders, order the count you need per termination. Mounting bolts for the pad are not part of the lug itself.
6) What is the manufacturer part number and country of origin for this Blackburn two-hole copper lug?
Manufacturer part number 32207, Blackburn brand, made in Mexico. That's the number to quote for a distributor cross-reference or a submittal.
