Blackburn CSP8 – Frequently Asked Questions
1) What wire size does the Blackburn CSP8 compression splice take?
The CSP8 is sized for 8 AWG stranded copper conductor, which is what the red color code on the barrel indicates. It is a compression splice, so it is crimped with a die-based tool rather than twisted or bolted, and it joins two conductors of that same size end to end.
2) Can I use the Blackburn CSP8 splice on aluminum conductor?
No. The CSP8 barrel is copper with a tin plating, and it is specified for copper conductor only. For an aluminum run, or for a copper-to-aluminum transition, you need a connector rated AL9CU or an aluminum-bodied splice instead. Putting bare aluminum into a copper-only barrel risks a corroding, high-resistance joint.
3) Is the CSP8 splice rated for medium voltage cable?
It carries a 35 kV voltage rating, so it is suitable for splicing conductor in medium voltage cable systems as well as ordinary building power. The rating applies to the connector itself; the insulation or splice kit built over it still has to match the cable class.
4) Is the Blackburn CSP8 UL listed?
Yes, the CSP8 is covered under UL file E9809. That file number is what an inspector or a spec writer will want to see referenced on a submittal for a compression splice.
5) What is the difference between a short barrel splice like the CSP8 and a long barrel splice?
A short barrel takes one crimp per conductor end and occupies less length, which matters when you are splicing inside a tight junction box, a handhole, or a crowded raceway. Long barrel versions give more crimp area and more mechanical hold, and are the usual pick for pulling tension or overhead runs. The CSP8 is the short barrel version in 8 AWG copper.
6) How do I confirm I am ordering the right Blackburn splice for 8 AWG?
Match the catalog number CSP8 and the red color code. Blackburn sizes its compression splices by conductor, and the red barrel is the 8 AWG stranded copper member of the range. If the conductor on the job is a different gauge, the CSP8 will not crimp correctly and you need the barrel sized for that AWG.
7) Why is the CSP8 barrel tin plated instead of bare copper?
The tin plating on the copper barrel resists oxidation, so the contact surface stays clean in damp vaults, underground boxes and outdoor enclosures where a bare copper barrel would dull. It also keeps the joint serviceable if the run later involves tinned conductor.
8) Do Blackburn CSP8 splices come in a bag or individually?
The CSP8 is sold each, so quantity on an order is a count of individual splices. Order one per joint, and remember a single conductor splice consumes one barrel across both cable ends.
