Blackburn CS73 AL SERVENTR COMP SPLICE A:1-2 B:1-2

The CS73 is a two-conductor compression splice with each side sized for 1-2 AWG, per the A:1-2 B:1-2 designation in the part description. Both barrels take the same range, so it splices a 1 or 2 AWG run to another 1 or 2 AWG conductor. Sold individually.

Yes. The CS73 complies with ANSI C119.4 when properly installed on aluminum-to-aluminum or aluminum-to-copper conductors, so it handles both all-aluminum runs and an aluminum-to-copper transition.

It's a bare compression splice, no insulation on the body. Once crimped you cover the joint yourself with tape, heat shrink, or a cold shrink sleeve appropriate to the service entrance location.

Compression only. The CS73 has no set screws or bolts, so installation takes a hydraulic or battery compression tool with the correct die for the barrel. If you want a wrench-installed joint instead, you need a mechanical set screw splice rather than this one.

RUS accepted, and it meets ANSI C119.4 when installed correctly on aluminum-to-aluminum or aluminum-to-copper conductors. That covers rural electric cooperative and utility service entrance work where an accepted connector is specified.

A compression splice is crimped permanently with a die tool, which gives a sealed, tamper-resistant joint suited to service entrance and buried or utility applications. A set screw connector is reusable and installs with hand tools, which is easier in a panel or where the joint may be opened later. The CS73 is the compression style, two-conductor, 1-2 AWG each side.

No. It's a straight two-conductor splice, one conductor into each end. For a tap off a through-run or a three-way connection you need an H-tap or a multi-port connector, not this splice.

Manufactured in Mexico and sold as a single piece, so quantity ordered equals number of splices received. Useful to know when you are counting connectors against conductor count on a service change.
