Blackburn SAC 750 CPTR700CPTTN – Frequently Asked Questions
1) What conductor sizes does the Blackburn SAC 750 CPTR700CPTTN reducer splice join?
It's a compression reducer that takes a 750 conductor on one end and a 700 on the other, so it's the part you use when a feeder steps down between those two sizes rather than running a same-size splice. Rated AL/CU, meaning it's approved for aluminum or copper conductors, including aluminum-to-copper transitions.
2) Can I use this Blackburn reducer to splice aluminum to copper in a wet or direct-buried location?
The connector is AL/CU rated and tin plated, which is what makes the aluminum-to-copper transition acceptable, and it's built to ANSI C119.4, the standard for connectors for use between aluminum and aluminum or aluminum and copper conductors. The barrel itself carries no insulation, so it is not a sealed splice on its own. For a wet or buried application you cover it with the insulating or re-jacketing system your spec calls for.
3) Will a 750-700 compression reducer fit inside my pull box or gutter?
Plan for a body 6.250 inches long with an outside diameter of 1.594 inches, plus whatever the compression tool and die need for clearance on both ends and the thickness of any tape or shrink build-up you add over it. In a tight box that overall length is usually the limiting dimension, not the diameter.
4) I need to splice two 750 conductors together, not reduce. Is this the right part?
No. This one is a reducer, 750 on one side and 700 on the other, so one end will not accept a 750 conductor. For a straight 750 to 750 joint you want a same-size compression splice rather than a reducing barrel.
5) Is this a bolted mechanical connector or does it need a crimp tool?
Compression only. There are no set screws or bolts, so installation requires the correct hydraulic compression tool and matching die set, and the number and order of crimps follows the connector markings. If your crew is not carrying compression tooling, a set-screw or bolted reducer is the path of less resistance.
6) Does the Blackburn SAC 750 CPTR700CPTTN come insulated, or do I have to cover it?
The barrel ships bare, with no insulation material on it. Insulation is field applied, typically tape, heat shrink, or a cold shrink sleeve, sized to clear the 1.594 inch outside diameter of the connector.
7) Is this connector made in the USA for a Buy American job?
Country of origin is the United States, which is the data point most public and federally funded projects want on the submittal for electrical connectors. Pair that with the ANSI C119.4 reference when you put the package together.
8) How is this Blackburn reducer sold, individually or in a bag?
Sold each, so the quantity you order is the number of connectors you get. Count one per conductor being spliced, not one per run, and add spares before the crew mobilizes since a compression splice can't be reused if a crimp goes wrong.
