Blackburn SAC 2 R 4 – Frequently Asked Questions
1) What does the Blackburn SAC 2 R 4 splice actually do, and what size conductors does it join?
The Blackburn SAC 2 R 4 is a compression splice reducer for aluminum conductor, made to join a 2 AWG run to a 4 AWG run in a straight inline splice. It takes two conductors, one in each barrel, and the reducer design is what lets the two different sizes come together in one connector instead of needing a same-size splice plus a separate reducing step.
2) Is the SAC 2 R 4 an insulated splice or does it need to be covered after crimping?
It is a bare connector with no insulation on it. The barrel is uninsulated aluminum with a bare surface finish, so the splice has to be insulated after crimping, whether that is tape, heat shrink, or a cover, unless it is landing somewhere insulation is not required. Plan that material into the job.
3) Do I need a crimp tool for this splice, or can it be set with a bolt or setscrew?
This is a compression connector, not a mechanical one. It has to be crimped with a hydraulic or battery compression tool using the correct dies, and the connector is marked for die 2 on the large end and die 4 on the reduced end. There is no bolt or setscrew on it, so a wrench-installed mechanical splice or a split bolt is what you want if a crimp tool is not available on site.
4) Can I use the SAC 2 R 4 on copper wire?
It is an aluminum-body splice built for aluminum conductor, and the description calls it out as an AL straight splice. For a copper-to-copper feeder splice, use a copper compression sleeve sized to the conductors instead. Where the job calls for aluminum joined to copper, specify a connector rated for that combination rather than assuming this one covers it.
5) How much room do I need in the box or enclosure for a Blackburn SAC 2 R 4 splice?
The connector is 3 inches long, so allow at least that much straight run plus bending radius on both conductors inside the pull box, handhole, or gutter. It is a straight inline body, not an offset or tee, so both conductors come in on the same axis.
6) Does this Blackburn splice meet the standard my inspector asks for on aluminum connections?
It is built to ANSI C119.4, the standard that covers connectors for use between aluminum and aluminum or aluminum and copper conductors. That is the reference normally cited on utility and feeder splice submittals.
7) What is the exact part number to specify for a 2 to 4 AWG aluminum reducing splice from Blackburn?
Order Blackburn SAC 2 R 4. The designation reads as splice, 2 AWG, reducing to 4 AWG, and it is made in the United States.
8) Is the SAC 2 R 4 sold as a single piece or in a bag?
It sells each, one connector per unit, so order the exact count of splices the job needs rather than by carton.
