Blackburn PC 2-1.75 – Frequently Asked Questions
1) What wire size does the Blackburn PC 2-1.75 splice accept?
The PC 2-1.75 is built for No. 2 conductors, and it is a two-conductor splice, so it joins one No. 2 to one No. 2 end to end. If your run is a different AWG, you need a different PC size; a compression barrel only grips the gauge it was sized for.
2) What does "oil stop" mean on this copper splice?
An oil stop splice carries an internal barrier between the two conductor entries so oil or compound cannot migrate through the barrel from one side to the other. That matters on service entrance work where a cable coming out of an oil-filled or compound-filled enclosure is spliced to a dry run. The PC 2-1.75 is that style, in copper, for No. 2.
3) Is the Blackburn PC 2-1.75 insulated, or do I have to tape or sleeve it?
Bare metal, no insulation on the connector itself. You finish it in the field, normally heat shrink or an insulating tape build-up appropriate to the voltage and the enclosure. Plan that material into the job before you crimp.
4) Can I use the PC 2-1.75 on aluminum conductors?
It is a copper splice, tin-plated. Use it on copper. The tin plating is there to protect the copper barrel and to keep the crimp from corroding in damp or buried enclosures; it does not make the connector dual-rated for aluminum. For aluminum or an aluminum-to-copper transition, specify a connector marked AL9CU.
5) Is this a compression splice or a set screw connector?
Compression. The PC 2-1.75 is crimped with a die-type compression tool, not tightened with set screws, so you need the correct tool and die for the barrel before you get to the splice. A mechanical set screw connector is the alternative if you have no crimper on site, but it is a different part.
6) How long is the Blackburn PC 2-1.75 barrel, and will it fit in a tight gutter?
Length is 1.750 inches. That is the number to check against the space you have in the pull box, meter socket or gutter, since you also need room to get compression dies around the barrel and to build your insulation back over it once it is crimped.
7) Is the Blackburn PC 2-1.75 sold individually or in a bag?
Sold each, one connector per unit, so order the exact count your splices call for plus spares. A miscrimped compression splice is cut out and replaced, not reworked, so carrying an extra on the truck is cheap insurance.
8) Where is the Blackburn PC 2-1.75 made? I have domestic sourcing requirements.
Country of origin is the United States. That is the detail institutional and government procurement usually needs on file for domestic preference documentation.
