Blackburn PAA59 – Frequently Asked Questions
1) What wire sizes does the Blackburn PAA59 parallel groove clamp take?
The PAA59 is built for 1/0 through 8 conductor range, and it holds two conductors, one in each groove. Anything outside that 1/0 to 8 window needs a different clamp body, since the groove depth is what develops the contact pressure.
2) Can I use an aluminum parallel groove clamp on copper conductors?
The PAA59 body is aluminum. Aluminum-bodied parallel groove clamps are for aluminum-to-aluminum service unless the clamp is specifically marked AL/CU for dual rating. If you are tapping or splicing copper, or mixing copper and aluminum in the same connector, pick a connector rated for that combination rather than this one.
3) Is the PAA59 a compression connector or a mechanical bolted one?
Bolted, not crimped. It functions as a wire or cable splice with the two conductors laid in parallel grooves and clamped by the bolts, so you need no hydraulic tool or die set, just a wrench. If your spec calls for a compression splice with a matched die, this is not the right part.
4) What size wrench or socket do I need to install the PAA59 clamp?
The bolts are 3/8 inch with a 9/16 inch head, so a 9/16 socket or box wrench does the job. Two bolts per clamp.
5) How much room does the Blackburn PAA59 need in an enclosure or on a pole?
Overall it measures Height 2-7/32 x Length 1-11/16 x Width 1-1/2 inch, so plan clearance for a 9/16 socket to swing on both bolts on top of that footprint.
6) Can I join two different wire sizes with the PAA59, like a 1/0 to a 6?
Yes, within the range. Each groove accepts a conductor from 1/0 through 8, and the two grooves are independent, so a larger and a smaller conductor can be spliced in the same clamp as long as both fall inside 1/0 to 8.
7) Is the Blackburn PAA59 insulated?
No insulation. It is a bare aluminum clamp, so any covering, tape, or insulating boot needed for the application has to be added separately.
8) Does the PAA59 come as a single clamp or in a bag of multiples?
It is sold each, one clamp per unit, so order one per splice point. For a grounding grid or multiple taps on a job, count your connections and order that quantity.
