Blackburn CSP30 – Frequently Asked Questions
1) What wire size does the Blackburn CSP30 splice take?
The CSP30 is sized for 3/0 stranded copper conductor, one size per connector. Compression splices are not multi-range, so 3/0 stranded is the only conductor it should be crimped onto. The orange color coding on the barrel is the size identifier, so an installer can verify the right splice on the reel before crimping.
2) Can I use the Blackburn CSP30 splice on aluminum conductor?
No. The CSP30 is a copper-bodied, tin plated splice intended for copper conductor. For aluminum or aluminum-to-copper work you need a connector specifically listed for AL or AL/CU service, not this one.
3) Is the CSP30 splice rated for medium voltage cable at 35 kV?
Yes, the splice carries a 35 kV voltage rating and is UL listed under file E9809. The connector itself is bare, so the voltage rating is realized only once the splice is insulated to the cable's system level with the appropriate tape, tubing, or splice kit.
4) Does the Blackburn CSP30 come insulated, or do I have to insulate the splice myself?
It ships bare. Insulation material is listed as none, meaning the tin plated copper barrel is exposed and the installer is responsible for rebuilding the insulation and jacket over the completed crimp. Order tape, heat shrink, or a cold shrink splice kit alongside it.
5) What does the short barrel on the CSP30 change compared to a long barrel splice?
A short barrel takes fewer crimps and occupies less axial length, which matters when you are splicing inside a tight pull box, handhole, or manhole where there isn't room to build out a long joint. A long barrel version gives more contact length for the same conductor. The CSP30 is the short barrel 3/0 stranded copper version.
6) Is the CSP30 a crimp splice or a mechanical set screw connector?
It is a compression splice, so it is installed with a hydraulic or battery crimp tool and the correct die for the barrel, not tightened with a hex key. If your crew is not carrying a crimper, a mechanical set screw splice is the alternative connector type for that situation.
7) How is the Blackburn CSP30 sold, individually or in packs?
It is sold each, so quantity ordered equals number of splices. The part number to order is CSP30.
8) Why is the Blackburn splice tin plated instead of bare copper?
Tin plating over the copper barrel slows oxidation on the contact surfaces, which keeps crimp resistance stable in damp underground vaults and handholes. It also makes the splice suitable for copper conductor without a separate inhibitor step for corrosion protection of the barrel itself.
