Blackburn PAA49 – Frequently Asked Questions
1) What wire sizes does the Blackburn PAA49 parallel groove clamp take?
The PAA49 is rated for conductors from 1/0 through 6. It's a two-conductor clamp, so both the run and the tap have to fall inside that 1/0 to 6 range. Anything larger than 1/0 or smaller than 6 needs a different body size.
2) Can I use an aluminum parallel groove clamp like the PAA49 on copper conductors?
The PAA49 body is aluminum. Aluminum-bodied parallel groove clamps are made for aluminum-to-aluminum connections unless the clamp is specifically marked AL/CU dual rated. Nothing in the PAA49 data marks it dual rated, so for copper runs or copper-to-aluminum taps, use a clamp listed for that combination rather than assuming this one covers it.
3) What size wrench or socket do I need to install the Blackburn PAA49 clamp?
The bolts are 3/8 inch with a 9/16 inch hex head, so a 9/16 socket or wrench does the job. Handy to know before you go up a pole or into a pedestal with the wrong tool.
4) How much room does the PAA49 parallel groove clamp need in a pedestal or enclosure?
Overall it measures 2-7/32 height by 1-3/16 length by 1-1/2 width in inches. That's the envelope to check against a crowded ground bar area or a shallow pedestal, plus clearance for a 9/16 wrench swing on the bolts.
5) Is the PAA49 a bolted connection or does it need a crimp tool?
Bolted. No press, no dies, no crimp head. You lay the two conductors in the grooves and torque the bolts down, which is why crews use these for field splices and taps where bringing a hydraulic crimper isn't practical.
6) What is a parallel groove clamp actually used for on a grounding job?
It joins two conductors running side by side, either as a splice or as a tap off a run. The PAA49 is built for wire or cable splicing duty and holds two conductors in machined grooves under bolt pressure, as opposed to a pipe or rod ground clamp that wraps a water pipe or ground rod. If you're bonding to a rod or a pipe, this is the wrong style of clamp.
7) Does the Blackburn PAA49 come as a complete clamp with bolts, and how is it sold?
Sold each, and it ships as an assembled two-bolt clamp with the 3/8 inch bolts in place. Order the quantity of individual clamps you need; there's no kit or contractor pack behind this part number.
8) Is the PAA49 insulated, or do I need to cover the connection?
Bare metal, no insulation on the clamp. If the splice sits somewhere that needs covering for protection or isolation, plan on tape, a boot, or a cover as a separate item.
9) What is the exact manufacturer part number for this Blackburn aluminum parallel groove clamp?
Blackburn PAA49 is the part number, one model with no size or finish variants behind it. Country of origin is India.
