Blackburn CU30 – Frequently Asked Questions
1) What wire size does the Blackburn CU30 splice connector take?
The Blackburn CU30 is sized for 3/0 stranded copper conductor, and it carries the orange die color code used to identify the correct crimp die for that size. Match the orange code on your compression tool die set when crimping it.
2) Is the CU30 splice a compression connector or a set-screw type?
It is a compression splice, crimped with a hydraulic or battery compression tool and the matching die. There are no screws or bolts to torque, so once it is crimped the joint is permanent.
3) Can I use this copper splice on aluminum conductor?
No. The CU30 is a copper-bodied, tin plated splice intended for copper conductor only. For aluminum or for an aluminum-to-copper transition you need a connector rated AL9CU or a dedicated aluminum barrel.
4) Does the CU30 splice come insulated, or do I have to tape or heat-shrink it?
It ships bare, with no insulation on the barrel. You insulate the finished crimp yourself with tape, heat shrink, a cold shrink tube, or a full splice kit appropriate to the system voltage.
5) What voltage is the Blackburn CU30 splice rated for?
Rated to 35 kV, so it can be used in medium-voltage splices as well as ordinary 600 V building work. The barrel itself is bare metal, so the voltage rating is realized through the insulating or shielded splice kit you build over it.
6) Why is the CU30 called a long barrel splice and does that matter for my install?
The long barrel gives room for two crimps per conductor end instead of one, which is what medium-voltage and high-pull applications usually call for. It also means you need more straight cable length in the pull box or manhole than a short barrel sleeve would need, so check your slack before cutting.
7) Is the Blackburn CU30 UL listed?
Yes. The splice is covered under UL file E9809.
8) Is the CU30 sold in bags or individually?
It is sold each, so you order exactly the number of splices the job needs rather than a fixed carton quantity. Remember a single conductor splice takes one barrel, so a three-phase run needs three plus one for the neutral if you are splicing it.
9) What is the exact manufacturer part number and country of origin for this Blackburn splice?
Blackburn part number CU30, manufactured in Mexico. Blackburn is the sub-brand label on the packaging.
