Blackburn SAC 350 R 2 TN – Frequently Asked Questions
1) What conductor sizes does the Blackburn SAC 350 R 2 splice reducer join?
The Blackburn SAC 350 R 2 TN is a compression reducer that splices a 350 kcmil conductor on one end to a 2 AWG conductor on the other. It is a single-piece barrel about 5 inches long, so it makes the size transition in one crimp assembly rather than requiring an adapter pin.
2) Can I use this Blackburn aluminum compression reducer on copper conductors, or only aluminum?
It is an aluminum body with a tin plated finish, which is the standard construction for a dual rated AL/CU compression connector, and the tin plating is what keeps the aluminum from reacting against a copper conductor. Use an oxide inhibitor on aluminum runs and crimp with the die and sequence the connector is marked for.
3) Is this splice insulated, or do I have to tape or shrink over it?
No insulation on it. The SAC 350 R 2 TN is a bare compression barrel, so the splice has to be insulated in the field, typically with heat shrink tubing or an insulating cover rated for the circuit voltage, unless it is landing inside an enclosure where a bare splice is acceptable.
4) Do I need a reducer like this or can I just use a standard 350 kcmil splice?
A straight splice has the same bore at both ends and will not grip a 2 AWG conductor coming into a 350 kcmil barrel. When the two conductors are different sizes, you want a reducing splice like the SAC 350 R 2 TN, which is bored 350 on one end and 2 AWG on the other. Only use a same size splice when both conductors match.
5) Am I buying one reducer or a pack?
Sold each. One order line of the SAC 350 R 2 TN gets you a single reducer, so count one per conductor being transitioned, which on a three phase plus neutral run means four.
6) Is the Blackburn SAC 350 R 2 TN made in the USA for a Buy American job?
Country of origin is the United States, which is what a government, school, or transit procurement package usually wants documented on electrical connectors. The part number to cite on the submittal is SAC 350 R 2 TN.
