Blackburn PAA29 – Frequently Asked Questions
1) What wire sizes does the Blackburn PAA29 parallel groove clamp take?
The PAA29 is built for a 4/0 through 2 conductor range, per the product name and description. It holds two conductors, one in each groove, and clamps them side by side with bolted pressure rather than a compression die.
2) Can I use an aluminum parallel groove clamp like the PAA29 on copper conductors?
The PAA29 body is aluminum. Aluminum-bodied parallel groove clamps are made for aluminum-to-aluminum runs; putting bare copper against an aluminum body creates a dissimilar metal couple that needs a plated or bimetallic connector instead. If you are tapping copper to aluminum, specify a bimetallic or tin-plated connector rated for that combination.
3) What size wrench or socket do I need to install the Blackburn PAA29?
Bring a 9/16 inch socket. The PAA29 uses a 5/16 inch bolt with a 9/16 inch head, so a standard 9/16 wrench or socket on a torque wrench does the job. There is one bolt clamping the two grooves.
4) How much room do I need for a Blackburn PAA29 parallel groove clamp?
Allow for a body measuring 1-13/16 inch height by 11-3/32 inch length by 1-3/8 inch width. That length is the driver: it is a long-barrel clamp, so it needs a clear parallel run of conductor rather than a tight pull box corner. Check the length against your enclosure or handhole before you commit.
5) Is the Blackburn PAA29 a compression connector or a bolted one?
Bolted. The PAA29 tightens down mechanically, so it installs with a wrench and no hydraulic crimp tool, and it can be taken apart later if the tap has to move. A compression splice is the alternative when you want a permanent, tool-crimped joint and do not need to re-enter it.
6) Does the Blackburn PAA29 come insulated?
No insulation. The PAA29 is a bare aluminum clamp with no insulating cover or boot, so if the splice needs covering you will be taping or adding a separate insulating cover on the job.
7) Is the Blackburn PAA29 sold individually or in a box?
It is sold each, one clamp per unit, under manufacturer part number PAA29. Order the count you need rather than a carton quantity.
