Blackburn PAC3459 – Frequently Asked Questions
1) What wire sizes does the Blackburn PAC3459 parallel groove clamp take?
The PAC3459 is rated for 1/0 through 8 conductors, and it holds two conductors at a time, one in each groove. If your run is larger than 1/0 or smaller than 8, it is the wrong clamp for that tap.
2) Can I use this aluminum clamp to connect a copper conductor without getting galvanic corrosion?
Yes. The PAC3459 body is aluminum but the grooves carry a copper liner, which is what lets it be used on copper as well as aluminum conductors instead of putting bare aluminum against copper. It is marked OI, meaning it is suitable for outdoor as well as indoor use.
3) Is the PAC3459 a bolted clamp or does it need a crimp tool?
It is a bolted connector, so it goes on with a wrench and no compression tool or die set is needed. That matters on service and repair work where you may need to open the connection later, and for crews who do not carry a hydraulic crimper.
4) What is a parallel groove clamp used for on a grounding job?
A parallel groove clamp joins two conductors running alongside each other, which is how you splice or tap a ground or bonding conductor without cutting into the main run. The PAC3459 is used as a wire or cable splice connector for that purpose, taking one conductor per groove.
5) How much room do I need in the enclosure or on the rack for this clamp?
The PAC3459 measures 2-7/32 inches in height by 1-18/32 inches in length by 1-1/4 inches in width, so plan clearance for a body of roughly that footprint plus wrench access to the bolt.
6) Does the PAC3459 come insulated, or do I need to tape or boot the connection?
It is supplied bare, with no insulation on the clamp. If the splice needs covering for your application, the insulating tape, boot or shrink is a separate item.
7) Is the Blackburn PAC3459 sold individually or in a box quantity?
It is sold each, so quantity one is a single clamp. Order one per splice point, and remember each clamp handles one pair of conductors.
8) What part number do I give my distributor for this Blackburn clamp?
Order it as Blackburn PAC3459. That is the manufacturer part number for the aluminum parallel groove clamp with copper liner, 1/0 to 8, outdoor/indoor rated.
