Blackburn CS78 – Frequently Asked Questions
1) What wire sizes does the Blackburn CS78 service entrance splice take?
The CS78 is sized for 1/0 conductor on both sides, run A and run B. It's a two-conductor splice, so one conductor in each end. If either side of your splice is a different size than 1/0, you need a different catalog number from the CS series rather than this one.
2) Can I use the Blackburn CS78 to splice aluminum to copper, or aluminum only?
Both. The CS78 complies with ANSI C119.4 when properly installed on aluminum-to-aluminum or aluminum-to-copper conductors, so it works as a transition splice as well as an all-aluminum splice. It is also RUS accepted, which matters on utility and rural electrification work.
3) Do I need a special crimp tool for the CS78 splice, or can I bolt it on?
It's a compression connector, not a mechanical set-screw type, so it has to be crimped with a hydraulic or battery compression tool and the correct die. The ANSI C119.4 compliance only holds when it's properly installed, which means the right die and full crimp cycles. If you need a connection you can make with a wrench instead, look at a mechanical set-screw splice rather than this one.
4) Is the Blackburn CS78 insulated, or do I have to tape or sleeve it after crimping?
It's a bare connector, with no insulation material on the body. Anything in an exposed or non-enclosed location needs to be insulated in the field, typically heat shrink or an insulating sleeve rated for the voltage of the run. In a service entrance box or enclosure where the splice is contained, the bare body is normally what's specified.
5) Blackburn CS78 vs a split-bolt or set-screw connector for a 1/0 aluminum service splice, which should I use?
Use the CS78 when the spec calls for a compression splice that meets ANSI C119.4 on aluminum or aluminum-to-copper, and you have a compression tool on site. A split-bolt or set-screw connector is the choice when you need to make the joint with hand tools, or need to open it again later for testing. The tradeoff is the tool: the CS78 is a one-shot crimp, permanent once compressed.
6) Is the Blackburn CS78 sold individually or in a bag of multiples?
Sold each. The order is one CS78 splice per unit, so count one per conductor pair you're joining, plus spares if you're crimping in a live service window.
7) What is the exact part number and who makes the CS78 service entrance splice?
Blackburn CS78 is the manufacturer part number, a 1/0 to 1/0 aluminum service entrance compression splice. Country of origin is Mexico. Order by CS78 to get the 1/0 by 1/0 configuration; adjacent numbers in the same series cover other conductor size combinations.
