Blackburn PAA339 – Frequently Asked Questions
1) What wire sizes does the Blackburn PAA339 parallel groove clamp take?
The PAA339 is the 2 through 6 AWG aluminum parallel groove clamp, as its catalog description indicates (AL PARAGRV CLAMP 1-2BOLT 2-6). It grips two conductors, one in each groove, in that range.
2) Can I use an aluminum parallel groove clamp like the PAA339 on copper conductors?
The body is aluminum, which is the standard choice for aluminum-to-aluminum taps and runs. Aluminum-bodied parallel groove clamps are only suitable for copper when the manufacturer rates them AL9CU (dual rated); that rating is not part of what the PAA339 carries here, so treat it as an aluminum conductor connector. For copper-to-copper grounding taps, use a copper or bronze bodied clamp instead.
3) Is the PAA339 a one-bolt or two-bolt clamp, and what size wrench do I need?
It is a single-bolt parallel groove clamp with a 3/8 inch bolt and a 9/16 inch bolt head, so a 9/16 socket or wrench does the job in the field.
4) How much room do I need in the enclosure or on the rack for a PAA339 clamp?
The clamp body measures 1-9/16 x 1-1/4 x 1-1/2 inches (height x length x width), plus clearance for a 9/16 inch socket on the bolt head. Compact enough for most pull boxes and ground bar runs, but allow wrench swing.
5) Is this clamp a compression fitting or does it bolt on?
Bolted. The PAA339 makes a mechanical wire or cable splice by clamping two conductors between grooved jaws and torquing the bolt, so no crimp tool or die set is needed, and it can be opened and re-made if a conductor changes.
6) Does the PAA339 come insulated?
No. It is a bare aluminum clamp with no insulation, so any covering on the finished splice has to be added separately with tape, a mold, or a cover. In grounding and bonding work it is normally left bare.
7) Is the PAA339 sold individually or in a box?
Sold each, so you order the exact count the job calls for rather than a fixed carton.
8) What part number do I give my supplier for the Blackburn 2-6 AWG parallel groove clamp?
Blackburn PAA339 is the manufacturer part number, and it is the only model in this configuration, aluminum, single bolt, 2 to 6 AWG.
