Blackburn PAE2121-79 – Frequently Asked Questions
1) Can I use an aluminum parallel groove clamp like the Blackburn PAE2121-79 on copper conductors?
The PAE2121-79 body is aluminum. Aluminum bodied parallel groove clamps are used for aluminum to aluminum runs, and dissimilar metal connections (aluminum to copper) require a connector rated for that combination, generally with an oxide inhibitor and a plated or bimetal body. If the job is copper to copper or copper to aluminum, specify a connector marked for those conductor materials rather than assuming this one covers it.
2) Is the PAE2121-79 clamp bolted or compression?
Bolted. The PAE2121-79 uses a 3/8 inch bolt to draw the two halves together on the conductors, so it installs with a wrench rather than a hydraulic or battery crimp tool. That makes it re-openable for re-tapping or inspection, which a compression splice is not.
3) How much room do I need in the enclosure or on the pole for this clamp?
The clamp body measures 2 x 1-3/8 x 1-5/8 inches, with a 3/8 inch bolt. Allow wrench swing on the bolt head on top of that footprint when you are working in a tight pedestal, handhole, or gutter.
4) Is the Blackburn PAE2121-79 insulated?
No. It is a bare aluminum clamp with no insulation on the body, so any splice made with it has to be taped, covered, or left in a location where bare connections are acceptable, such as a grounding electrode conductor tap.
5) Does the PAE2121-79 come in a bag or box of multiples?
It sells as a single clamp, one each. Order one per connection point and add a spare if you are splicing a run of taps.
6) What is the correct Blackburn part number and manufacturer number for this parallel groove clamp?
Blackburn PAE2121-79, and the manufacturer part number is the same, PAE2121-79. It is an extruded parallel groove clamp used as a wire or cable splice connector.
