Blackburn CSP2 – Frequently Asked Questions
1) What wire size does the Blackburn CSP2 compression splice take?
The CSP2 is sized for 3 to 2 stranded copper conductors, and it is color coded brown so crews can identify the die and range on the job. Both ends of the barrel take the same range, so it splices 3 STR to 2 STR or like to like.
2) Can I use a copper compression splice like this on medium voltage cable?
Yes. The CSP2 carries a 35 kV voltage rating, so it is suitable for medium voltage splicing as well as low voltage work, provided the splice is insulated or re-jacketed to the same class.
3) Can I use the CSP2 on aluminum conductors?
No. It is a copper splice and should be used on copper conductors only. For aluminum, or for an aluminum to copper transition, you need a connector rated AL9CU or equivalent dual rated compression splice.
4) Is this a crimp splice or a mechanical set screw connector?
It is a compression splice: a copper barrel you crimp with a hydraulic or battery tool and the matching die, not a set screw or split bolt connector. If you need a reusable, tool free connection, a mechanical set screw splice is the better choice; compression gives you a permanent, sealed joint.
5) Why is the CSP2 called a short barrel splice, and does that change the crimp?
Short barrel means less barrel length per conductor than a long barrel splice, which matters when you are working in a tight pull box or a crowded splice cabinet. Fewer crimps are needed per side than on a long barrel of the same range, so follow the die and crimp count called out for the CSP2 rather than assuming a long barrel pattern.
6) Will a tin plated copper splice corrode in a wet or direct burial location?
The barrel is copper with a tin plated finish, which resists oxidation and is the standard plating for copper connectors used in damp, buried, or outdoor enclosures. Tin plating also lets it land on copper conductors without the galvanic concern you get pairing bare dissimilar metals.
7) How is the Blackburn CSP2 sold, individually or in bags?
Sold each, so you can order the exact count for the splice kit or job rather than a bagged quantity. Order under manufacturer part number CSP2.
8) Where is the Blackburn CSP2 splice made?
Country of origin is Mexico. Useful if you are compiling origin documentation for a government or institutional submittal package.
