Blackburn CU6 – Frequently Asked Questions
1) What wire size does the Blackburn CU6 splice connector take?
The CU6 is sized for 6 AWG stranded copper conductor, which is what the "6STR" in the part description refers to. It is a compression splice, so it is crimped onto the conductor rather than screwed down, and the blue color coding identifies the die and size group at a glance on the job.
2) Is the Blackburn CU6 splice insulated, or do I have to tape or heat shrink it?
It is a bare connector with no insulation, so the splice has to be insulated after crimping using tape, heat shrink, or a cold shrink sleeve appropriate to the circuit voltage. Nothing for insulating is included, and it ships as a single piece.
3) Can I use the Blackburn CU6 on aluminum wire?
No. The CU6 is a copper-only splice, tin plated for corrosion resistance. For aluminum or for an aluminum-to-copper transition you need a connector marked AL9CU or AL rated, not this one.
4) What voltage is the Blackburn CU6 splice rated for?
Rated to 35 kV, so it is suitable for medium voltage splicing as well as ordinary line voltage work, provided the insulation system you build over it is rated for the circuit. The rating belongs to the connector, not to any covering, since none is supplied.
5) Is the Blackburn CU6 UL listed?
It carries UL file E9809. That is the reference an inspector or a spec writer will want when a compression splice has to be shown as a listed component on a medium voltage or feeder splice.
6) What does "long barrel" mean on this Blackburn splice, and when do I want it?
Long barrel means extra crimp length, so the splice takes two or more crimps per side instead of one. That gives more contact area and better pullout resistance, which is why long barrel splices get specified on feeders and underground runs that see mechanical stress. Short barrel versions exist for tight enclosures where length is the constraint.
7) Do I need a special crimping tool for the Blackburn CU6?
Yes, it is a compression connector, so it needs a hydraulic or mechanical compression tool with the die matched to the connector's color code. The blue coding on the CU6 tells you which die to set. A mechanical screw type lug or split bolt is the alternative if you have no compression tool on site.
8) How is the Blackburn CU6 sold, individually or in a bag?
Each. One CU6 splice per unit, ordered under manufacturer part number CU6, so count one per splice point and buy spares for the crimps you spoil.
