Blackburn PAC793 – Frequently Asked Questions
1) What conductor range does the Blackburn PAC793 parallel groove clamp cover?
The PAC793 covers 336.4 kcmil down to 1/0, as noted in its 336-1/0 rating. It takes two conductors, one in each groove, so you can tap or run a parallel connection anywhere in that range without changing clamps.
2) Can I use an aluminum parallel groove clamp on copper conductor?
The PAC793 body is aluminum. Aluminum bodied parallel groove clamps are made for aluminum conductor; putting bare copper directly against aluminum sets up a dissimilar metal couple that corrodes. If your run is copper, use a clamp rated for copper or a bimetallic connector instead.
3) Does the PAC793 come with joint compound already applied?
Yes. It ships with Contax compound factory applied in the grooves, so you do not need to add a separate inhibitor before torquing the bolts. Wire brush the conductor, seat it in the groove, and tighten.
4) Is this a bolted clamp or does it need a crimp tool?
Bolted. No press, die set, or battery crimper needed, which is why parallel groove clamps like the PAC793 get used for field taps and repairs where hauling a hydraulic tool is not practical. A compression splice is the alternative if you want a permanent one piece joint.
5) How much room do I need around the conductor to fit this clamp?
The PAC793 measures Height 2-15/32 x Length 1-5/8 x Width 1-7/8 inch. Allow clearance for a wrench on the bolts on top of that, so it is not the part for tight cabinet gutters or crowded riser stacks.
6) Is the PAC793 insulated?
No insulation on this clamp, it is a bare aluminum body. Any completed joint that needs to be covered has to be taped or boot insulated in the field, or kept in a location where a bare connection is acceptable.
7) Do parallel groove clamps ship in bags or individually?
The PAC793 is sold each, so you order the exact count the job needs rather than a carton quantity. Model number to specify is PAC793.
