Blackburn AC 2 TN AL Comp Reducer, Tin Plated No2

The AC 2 TN is a compression splice reducer for aluminum conductor, used to join two conductors of different sizes in one crimped connection instead of a bolted lug pair. It is a compression connection, not mechanical, so it needs the proper die and hydraulic crimping tool to install. The body is 3-15/32 inches long and comes bare, with no insulation on it, so it has to be taped or covered per your installation practice.

It is built to ANSI C119.4, the standard covering connectors for use between aluminum and aluminum or aluminum and copper conductors. That is the reference an electrical inspector or utility spec typically cites for a compression splice of this type.

It ships bare. Insulation material on the AC 2 TN is listed as none, so after crimping you cover it yourself with tape, heat shrink, or a cover appropriate to the voltage and location.

The tin plating on the AC 2 TN is what makes it suitable for aluminum-to-copper work, since tin over an aluminum body is the standard AL9CU-style dual-rated construction and keeps the dissimilar metals from corroding at the joint. It is described as an aluminum compression reducer with a tin-plated surface finish. Match the conductor sizes to the connector's rated range before crimping.

Two. It is a two-conductor splice, one conductor in each barrel, which is what makes it a reducer rather than a multi-tap connector. If you need to land three or more runs, this is the wrong part and you want a multi-port compression or mechanical connector.

Country of origin on the AC 2 TN is the United States, which is the line a government, school district, or utility procurement officer usually needs for a domestic-content submittal.

Each. The AC 2 TN reducer is sold as a single piece, so order one per splice you are making.
