Blackburn ACJ397 – Frequently Asked Questions
1) What is the Blackburn ACJ397 splice used for?
The ACJ397 is an aluminum full tension compression splice for joining two conductor ends in a run. It is a compression connection, so it is made with a hydraulic or battery crimp tool and the proper die, not bolted or set-screwed. Full tension means the splice is intended to carry the mechanical load of the conductor as well as the current, which is what overhead spans require.
2) Does the Blackburn ACJ397 compression splice meet ANSI C119.4?
Yes. The ACJ397 is built to ANSI C119.4, the standard covering connectors used between aluminum and copper conductors in underground and overhead distribution. If your utility or spec sheet calls for a C119.4 connector, this one qualifies.
3) Do I need a special tool to install the ACJ397 splice?
Yes. This is a compression connector, so it is installed with a hydraulic or battery-powered crimp tool and the die matched to the splice. There is no bolt or screw on it, and a hand plier crimp will not produce a full tension joint.
4) Is the ACJ397 splice insulated?
No, it is a bare aluminum splice with no insulation on the body. Any covering, tape, or sleeving over the finished joint has to be supplied separately and selected for the voltage and environment of the run.
5) Can I use the Blackburn ACJ397 on copper conductor?
The ACJ397 is an aluminum-bodied splice sized for 397 conductor. Aluminum compression splices are made for aluminum and ACSR conductor; for a copper run, use a copper compression splice sized to that conductor rather than this one.
6) How is the Blackburn ACJ397 sold, individually or in a box?
It is sold each, one splice per unit, so order one per joint. Crews splicing a three-phase run typically take three plus spares, since a mis-crimped compression splice cannot be reopened and reused.
