Blackburn PAE3939-79-3B – Frequently Asked Questions
1) Is this a bolted clamp or a compression connector?
Bolted. The PAE3939-79-3B uses a 1/2 inch bolt to clamp the two conductors in parallel grooves, so it installs with a wrench and no hydraulic tool or die set. If your spec calls for an irreversible compression splice, this is not that connector.
2) Can I use an aluminum parallel groove clamp on copper conductors?
The PAE3939-79-3B body is aluminum and it ships with contact aid (the W/CONTX in the description), which is the oxide inhibiting compound aluminum connections need. Aluminum bodied parallel groove clamps of this kind are commonly dual rated for copper and aluminum, but that rating is not something to assume - match the clamp to the conductor metal your drawing calls out.
3) Do I need to add joint compound when installing this Blackburn clamp?
No separate tube is required. Contact aid comes with the clamp, so the oxide inhibitor is already in the package. Wire brush the conductor, apply the compound, seat both cables in the grooves and torque the bolt.
4) How much room does the PAE3939-79-3B need in the enclosure or on the structure?
The clamp measures 2-9/16 height by 3-3/8 length by 2-5/16 width in inches, plus wrench clearance for the 1/2 inch bolt head. Worth checking against tight risers, pull boxes and pole top space before you commit to it.
5) What part number do I give my distributor for the 397 to 3/0 aluminum parallel groove clamp?
Blackburn PAE3939-79-3B. That is the manufacturer part number for the aluminum parallel groove clamp supplied with contact aid, covering a 397 run to 3/0 tap. Country of origin is Mexico.
6) Is the Blackburn PAE3939-79-3B insulated?
It is a bare metal clamp with no insulation. Any covering, tape or shrink over the finished joint has to be supplied separately to suit the application.
7) Is this clamp sold individually or in a box?
Sold each. One PAE3939-79-3B clamp per unit, so order one per splice point rather than by carton.
