Blackburn SAC 750 CPTTN – Frequently Asked Questions
1) Can the Blackburn SAC 750 splice be used on both aluminum and copper conductors?
Yes. The SAC 750 CPTTN is a dual-rated AL/CU compression splice, so it accepts aluminum or copper 750 kcmil conductors and can be used to splice aluminum to copper. The tin-plated barrel is what makes the copper side workable, since tin plating separates dissimilar metals at the contact surface.
2) Does the Blackburn SAC 750 CPTTN come with insulation or a cover?
No insulation is supplied on the SAC 750 CPTTN, it is a bare tin-plated barrel. You insulate the finished splice in the field with tape, heat shrink, or a cold-shrink sleeve sized for 750 kcmil cable. Budget for that material when you order.
3) Does this Blackburn splice meet ANSI C119.4 for underground and service entrance connectors?
Yes, the SAC 750 CPTTN is built to ANSI C119.4, the standard covering connectors for use between aluminum and copper conductors in underground and similar installations. That is the line item most utility and institutional specs call out for a 750 kcmil service entrance splice.
4) How long is the Blackburn SAC 750 compression splice, and will it fit in my pull box or handhole?
The barrel is 7 inches long, so allow at least that plus bending radius and your insulation buildup inside the enclosure. In a tight handhole or a shallow gutter, measure before you cut the cable, a 750 kcmil conductor has very little slack once it is trimmed.
5) How many conductors does the SAC 750 splice join?
Two. It is a straight two-way butt splice, one 750 kcmil conductor entering each end. For a tap or a three-way connection you need a different body style, not this splice.
6) Do I need a hydraulic crimper for the SAC 750, or can it be set with a hand tool?
It is a compression splice, not a mechanical set-screw type, so it has to be crimped. At 750 kcmil that means a hydraulic or battery hydraulic tool with the die set matched to the connector barrel. There are no bolts to torque and no way to install it with a wrench.
7) Should I use a compression splice like this or a mechanical set-screw connector for a 750 kcmil repair?
A compression splice such as the SAC 750 CPTTN gives a permanent, sealed-geometry joint and is what most specs require for direct-buried and service entrance work under ANSI C119.4. A mechanical set-screw connector installs with hand tools and can be taken apart later, which is the better choice if you need a re-enterable joint or have no hydraulic tooling on site. If the joint has to stay put and pass inspection against a C119.4 callout, go compression.
8) Is the SAC 750 splice made in the USA for projects with domestic sourcing requirements?
Country of origin is the United States, which covers the Buy American style documentation many government, education, and healthcare procurement packages ask for on electrical connectors. The part number to cite is Blackburn SAC 750 CPTTN.
9) Is the Blackburn SAC 750 CPTTN sold individually or in a bag of multiples?
Sold each. One splice per unit, so for a three-phase-plus-neutral 750 kcmil run you would order four, plus whatever spares your crew wants on the truck.
