Blackburn CU8 – Frequently Asked Questions
1) What wire size does the Blackburn CU8 splice take?
The CU8 is sized for 8 AWG stranded copper conductor, and the red color code is the identifier for that size on Blackburn's compression line. It is a compression splice, so it joins two 8 AWG stranded copper conductors end to end in one barrel.
2) Can I use the Blackburn CU8 splice on medium voltage cable?
Yes. The CU8 carries a 35 kV voltage rating, so it is suitable for medium voltage conductor splicing as well as low voltage work, provided the splice is insulated and re-jacketed per the cable system's requirements.
3) Is the CU8 splice copper only, or can it be used on aluminum conductor?
Copper only. The barrel is copper with a tin plated finish, and the part is designated CU, which means it is rated for copper conductor. For aluminum or for an aluminum to copper transition you need a connector marked AL9CU or AL, not this one.
4) Is the Blackburn CU8 a UL listed splice connector?
It is covered under UL file E9809. That is the reference an inspector or a spec writer will want for a compression splice on a permanent installation.
5) Why does the Blackburn CU8 have a long barrel?
A long barrel gives room for two crimps per conductor side instead of one, which is what many specs and utility standards call for on a splice that has to carry full conductor ampacity or see mechanical pull. If your crimp spec only calls for a single indent per side, a short barrel splice does the same electrical job in less space.
6) Do I need a special crimp tool for the Blackburn CU8 splice?
Yes, it is a compression connector, not a mechanical setscrew or split bolt type, so it has to be installed with a hydraulic or battery compression tool using the die index stamped on the barrel. Nothing is included with the connector, it is sold as a single piece, so the tool and dies are a separate line on your order.
7) What is the manufacturer part number for the red 8 AWG Blackburn long barrel splice?
Blackburn CU8. That is the full catalog number a distributor or counter will cross on, and the color red plus the CU prefix confirm you have the 8 AWG stranded copper version.
8) Does the tin plating on the CU8 matter for outdoor or damp locations?
It helps. Tin plating over the copper barrel slows oxidation at the conductor interface, which is why tinned compression connectors are the normal choice in handholes, vaults, and wet or corrosive locations rather than bare copper.
