Blackburn CS71 – Frequently Asked Questions
1) What conductor sizes does the Blackburn CS71 service entrance splice take?
The CS71 is a two-port service entrance compression splice: the A side takes 1 through 2 AWG and the B side takes 6 AWG. It joins two conductors, so it is a run-to-tap style splice rather than a multi-tap block.
2) Can I use the CS71 splice to connect aluminum to copper?
Yes. The CS71 complies with ANSI C119.4 when properly installed on aluminum-to-aluminum or aluminum-to-copper conductors, and it is also RUS accepted. That makes it usable for the aluminum service entrance cable to copper transition you typically hit at a meter can or service head.
3) Does the Blackburn CS71 come insulated, or do I have to cover it myself?
It ships bare. The insulation material is listed as none, so the splice body is uninsulated and you finish it in the field with heat shrink, a cold shrink tube, or tape rated for the application. Plan that material into the job.
4) Is the CS71 a compression splice or a set screw connector?
Compression. The CS71 is crimped with a hydraulic or battery compression tool and the correct die, not tightened with a hex key. If you want a connector you can install with a screwdriver or wrench, you need a mechanical set screw splice instead.
5) What part number and manufacturer should I spec for an aluminum service entrance splice reducing 1/2 AWG to 6 AWG?
Blackburn CS71. That is the manufacturer part number as well, and the unit is made in Mexico. Spec it as an aluminum-bodied compression service entrance splice, dual port, A side 1-2 AWG and B side 6 AWG.
6) How is the Blackburn CS71 sold, individually or in a bag?
Sold each. One CS71 splice per unit, so order one per connection you are making. On a typical single phase service entrance splice-out you will need one per current-carrying conductor plus one for the neutral if the sizes match the A and B ports.
7) What does the 2 inch size on the CS71 refer to?
The catalogue size for the CS71 is given as 2 inch, which relates to the body of the splice, not the conductor range. Size your conductors off the port ratings: 1-2 AWG on the A side and 6 AWG on the B side.
