Blackburn SAC 1000 CPT R 750 – Frequently Asked Questions
1) What does the Blackburn SAC 1000 CPT R 750 reducer splice actually connect?
It is a compression splice reducer for joining two different aluminum conductor sizes, 1000 to 750 per the Blackburn model designation. Rather than a straight splice of like sizes, a reducer has two different barrel bores so you can transition a run down a size without a separate adapter. Crimped, not bolted, and sold each.
2) Is the SAC 1000 CPT R 750 splice insulated, or do I still have to tape or heat-shrink it?
No insulation on it at all. The barrel is bare aluminum with no factory covering or finish, so the installer supplies the insulation, whether that's tape, a heat-shrink sleeve, or a cold-shrink kit sized to the 1.841 inch outside diameter. Plan for that in the splice-box fill and bend space.
3) Will a 1000-750 compression reducer fit inside my pull box or handhole?
Check the length first. The body is 7 inches long with a 1.841 inch outside diameter, and once you add the insulation you apply over it plus the conductor bend radius on both ends, this is not something that drops into a shallow box. It is normally landed in a pull box, handhole, or splice enclosure with room for a full 7 inch barrel plus covering.
4) Does this splice meet the connector standard our specs call out for underground and secondary connections?
It is built to ANSI C119.4, the standard for electric connectors used on insulated and non-insulated conductors, which is the clause most utility and institutional specs cite for compression splices. It is also made in the United States, which matters on Buy American and federally funded work.
5) Is the Blackburn SAC 1000 CPT R 750 for aluminum or copper conductors?
Aluminum. The SAC series barrel is aluminum bodied and factory filled for aluminum conductor, and it ships bare with no plating or insulation. If your run is copper on one side, you want a dual-rated or bimetallic transition connector instead, not this one.
6) Can I install this Blackburn reducer with a hand crimper, or do I need a hydraulic tool?
A barrel this size is compression only, no bolts or set screws, and at 1.841 inch outside diameter over a 1000 kcmil bore it takes a hydraulic crimper with the correct die set and the number of crimps the connector is rated for. A mechanical hand tool will not develop the force. Verify the die index stamped on the connector body before you crimp.
7) How is this different from a straight compression splice of the same size?
A straight splice has the same bore on both ends and joins two conductors of equal size. This is a reducer, so the two ends are bored differently, 1000 on one end and 750 on the other, letting you make the size transition in a single crimped barrel instead of splicing to a full-size length and then stepping down. Same compression method, different geometry.
8) How is this reducer sold, individually or by the box?
Each. One connector per unit, so order one per splice you are making and plan a spare or two, since a mis-crimped compression barrel cannot be reused.
