Blackburn PAE3939-79-2 – Frequently Asked Questions
1) What conductor sizes does the Blackburn PAE3939-79-2 parallel groove clamp take?
The PAE3939-79-2 is rated for the 397 to 3/0 range called out in its designation, with one groove for the larger run conductor and one for the smaller tap. It holds two conductors, so it is a single run-to-tap connection, not a multi-tap body.
2) Can I use this aluminum parallel groove clamp on copper conductors?
The body is aluminum, and the PAE3939-79-2 ships with contact compound (the CONTX in the description), which is what allows an aluminum clamp to be used on aluminum and on aluminum-to-copper combinations without relying on a separately purchased inhibitor. Copper-to-copper only runs are normally made with a copper or bronze clamp instead.
3) How is this clamp tightened, and what size wrench do I need?
It is a bolted connection, not a compression fitting, so no crimp tool or die set is required. The bolt is 1/2 inch, so a standard 1/2 inch hardware wrench or socket does the job in the field.
4) How much room do I need in the enclosure or on the structure for this parallel groove clamp?
Plan for a body measuring 2-9/16 inch height by 3-3/8 inch length by 2-5/16 inch width, plus wrench swing for the 1/2 inch bolt. That is a substantial footprint, so check clearance before committing to it inside a tight pedestal or pull box.
5) Is the Blackburn PAE3939-79-2 an insulated connector?
No. It is a bare aluminum clamp with no insulation, so any required cover, tape, or shrink insulation has to be supplied separately for the application.
6) Do I get one clamp or a pack when I order PAE3939-79-2?
Pricing and shipping are per each, so one order quantity equals one clamp with its contact compound. Multiply by the number of taps on the job.
