Blackburn PAC79 – Frequently Asked Questions
1) What conductor sizes does the Blackburn PAC79 parallel groove clamp take?
The PAC79 is a two-conductor parallel groove clamp rated for a range of 336 through 1/0, with each of the two grooves holding one run. It connects two conductors side by side rather than tapping a ground rod, so both runs must fall inside that range.
2) Can I use this clamp to splice an aluminum conductor to a copper conductor?
Yes. The PAC79 has an aluminum body with a copper liner, which is what lets a copper run land in the clamp without sitting directly against the aluminum casting. That is the reason to pick this version over a plain aluminum-bodied parallel groove clamp.
3) Is the PAC79 a bolted clamp or does it need a compression tool?
It is a bolted connector, tightened with a wrench, so no hydraulic or battery crimp tool is needed on the pole or in the pit. That also means it can be loosened and reworked if a conductor has to be repositioned, unlike a compression sleeve.
4) How much room do I need in the enclosure or on the crossarm for this clamp?
The PAC79 body measures 2-15/32 inch height by 1-5/8 inch length by 1-7/8 inch width. Worth checking against tight gutter or hand-hole clearances before you commit, since parallel groove clamps also need wrench swing on the bolt.
5) Is the Blackburn PAC79 insulated, and does it need taping or a cover?
No insulation is supplied with the clamp; it is a bare metal bolted connector. Any covering or protection required at the splice for your application has to be added separately.
6) Is the PAC79 sold individually or in a box?
It ships as a single clamp, priced and sold each, so order one unit per splice point you are making.
7) What is the exact part number and manufacturer for the PAC79 ground clamp?
It is Blackburn part number PAC79, an aluminum parallel groove clamp with copper liner for 336-1/0 conductors, manufactured in India.
