Blackburn SAC 350 TN – Frequently Asked Questions
1) What conductor size does the Blackburn SAC 350 TN compression splice take?
The SAC 350 TN is built for 350 kcmil aluminum conductor, joining two runs end to end. It is a two-conductor splice, one cable in each end, and the barrel is 5 inches long overall.
2) Can I use the Blackburn SAC 350 splice on copper cable as well as aluminum?
Tin plating on the aluminum body is what makes it dual rated in practice: the tin barrier keeps the aluminum body from galvanic attack at a copper interface. The splice itself is aluminum bodied and tin plated, and it is listed to ANSI C119.4, the standard covering connectors for aluminum and copper conductors. Confirm the 350 kcmil size matches on both runs before crimping.
3) Does the SAC 350 TN splice come insulated, or do I have to tape or shrink it?
It ships bare. There is no insulation on the splice, so the installer covers it after crimping, typically with heat shrink, a cold shrink tube, or tape build-up appropriate to the circuit voltage. Budget for that material on the job, it is not supplied with the connector.
4) Is this a compression splice or a set-screw (mechanical) connector?
Compression. The SAC 350 TN is crimped with a hydraulic or battery compression tool and the correct die for 350 kcmil, not tightened with a set screw. If you need something you can install with a hex key and re-enter later, a mechanical set-screw splice is the type to look for instead.
5) Does the Blackburn SAC 350 TN meet ANSI C119.4 for underground and direct-buried splices?
The splice is listed to ANSI C119.4, the connector standard for splices and taps on insulated and bare aluminum and copper conductors. That is the reference specification engineers usually call out on a distribution or feeder drawing.
6) How is the SAC 350 TN sold, individually or in a box?
Sold each, one splice per unit, so you can order the exact count for the number of joints on the run rather than a carton quantity.
7) Is the Blackburn SAC 350 TN made in the USA for a government or public-works spec?
Country of origin is the United States, which is what a procurement officer needs for a domestic-content or Buy American line item. The part number to cite is SAC 350 TN.
