Blackburn CU20 – Frequently Asked Questions
1) What wire size does the Blackburn CU20 splice connector take?
The CU20 is sized for 2/0 stranded copper conductor, one size per barrel, and it splices 2/0 to 2/0. It is a compression splice, so it is crimped with a die-matched tool rather than bolted. If your run is a different AWG, you need the corresponding Blackburn CU-series barrel, not this one.
2) Can I use the CU20 splice on aluminum conductor?
No. The CU20 is a copper-only barrel, tin plated. For aluminum or for an aluminum-to-copper transition you need a connector rated AL9CU or an aluminum-bodied splice. Putting bare copper on aluminum invites galvanic corrosion at the joint.
3) What voltage can this Blackburn compression splice be used at?
The CU20 carries a 35 kV rating, so it is suitable for medium-voltage feeder splicing as well as ordinary 600 V work. It is UL listed under file E9809.
4) Does the CU20 splice come insulated, or do I have to cover it myself?
It ships bare. Insulation material is listed as none, so the splice is a plain metal barrel and you provide the insulation, whether that is tape build-up, heat shrink, or a cold-shrink splice kit appropriate to the system voltage.
5) What does the long barrel mean on this splice, and why would I want it?
Long barrel means more crimp length per side, which lets you place multiple crimps on each conductor for a higher pull-out and lower-resistance joint. That is what you want on heavy feeder runs and medium-voltage cable where the splice carries mechanical load.
6) What part number should I order for a 2/0 copper compression splice from Blackburn?
Order Blackburn CU20. That is the manufacturer part number for the tin plated copper long barrel splice for 2/0 stranded copper, made in Mexico.
7) Why is the CU20 barrel tin plated and black?
The tin plating protects the copper barrel and keeps the contact surface clean for crimping. The black color is Blackburn's size-coding on the CU series, which matches the color band on the die and lets an inspector confirm from a distance that the right barrel was used for 2/0.
