Thomas & Betts CSP1 – Frequently Asked Questions

1) What is the Thomas & Betts CSP1 splice used for?
The CSP1 is a short barrel compression splice for joining copper wire or cable. It's a Blackburn product made of copper with a tin plated finish, and it's a compression fitting, so it's crimped with a die tool rather than bolted or twisted on.
2) Can the CSP1 copper splice be used on medium voltage cable?
Yes. The CSP1 carries a 35 kV voltage rating, which puts it in medium voltage service, not just line voltage branch circuit work.
3) Will the CSP1 splice work on aluminum conductor?
No. The CSP1 is a copper body splice, rated for copper conductor. For aluminum or for an aluminum to copper transition you need a dual rated AL9CU connector instead; putting bare aluminum into a copper only barrel risks a galvanic problem at the joint.
4) What does the green color on the CSP1 splice mean?
Green is the die color code for this Blackburn splice. Compression connectors are color coded so the crimper operator can match the connector to the correct die and number of crimps; the CSP1 is the green code, and the barrel is also stamped to confirm it on the job.
5) Why choose a short barrel splice instead of a long barrel one?
Short barrel splices take fewer crimps and occupy less length, which matters when you're splicing in a tight pull box, a manhole rack, or under a cover where a long barrel won't lie straight. A long barrel gives more contact length and more crimps for higher pull-out resistance on heavy feeder work. The CSP1 is the short barrel version.
6) Does the tin plating on the CSP1 matter for underground or wet locations?
Tin plating over the copper barrel slows oxidation on the contact surfaces, which is why plated splices are the usual pick for damp, buried, or manhole work where a bare copper joint would dull before it's crimped. The CSP1 is tin plated copper.
7) Is the CSP1 splice sold individually or in a bag?
The CSP1 is sold each, so order the exact count you need rather than a fixed carton quantity.
8) What part number should I order for this Blackburn short barrel copper splice?
Order by manufacturer part number CSP1 from Thomas & Betts, sold under the Blackburn sub-brand.
