Blackburn PAC7 – Frequently Asked Questions
1) What conductor sizes does the Blackburn PAC7 parallel groove clamp take?
The PAC7 is built for a main run of 336 kcmil down to a tap of 1/0, and it holds two conductors, one in each groove. Sizes outside that 336 to 1/0 window need a different clamp in the parallel groove line.
2) Can I use an aluminum parallel groove clamp to connect copper to aluminum?
Yes, that is exactly what the PAC7 is for. The body is aluminum with a copper liner in the groove, so a copper conductor is separated from the aluminum body and you get a dual rated copper to aluminum connection without direct dissimilar metal contact.
3) Is the Blackburn PAC7 a bolted clamp or does it need a compression tool?
Bolted. The PAC7 tightens down with its bolt, so a lineman or electrician installs it with a wrench, no hydraulic press or die set. That also means it can be loosened and re-tensioned if a tap has to be moved.
4) How much room do I need for a PAC7 clamp on a crowded pole or in a pedestal?
Plan for a footprint of 2-15/32 inch height by 1-5/8 inch length by 1-7/8 inch width. That is the overall body, so allow clearance above it for wrench swing on the bolt.
5) Does the Blackburn PAC7 carry any utility listing for co-op or REA work?
It is RUS Listed, which is the acceptance utilities and rural electric cooperatives typically call out on distribution material submittals.
6) What is the difference between a parallel groove clamp and a split bolt for a tap connection?
A parallel groove clamp like the PAC7 lays both conductors side by side in machined grooves and clamps them with a bolt, which suits a large main to smaller tap, here 336 kcmil to 1/0, and lets you back it off and redo the tap. A split bolt squeezes two conductors together in one barrel and is generally a smaller-range, permanent-feeling connector. Where copper meets aluminum, the copper liner in the PAC7 groove is the reason to pick the parallel groove version.
7) Is the PAC7 insulated, or do I need to cover the connection?
Bare metal, no insulation on the clamp. If the splice sits where it needs covering, the tape, boot, or cover is a separate item you buy alongside it.
8) Do PAC7 clamps ship in boxes of ten or can I buy one?
Sold each, so you can order a single PAC7 or the exact count a job needs rather than a carton quantity. The orderable part number is PAC7.
