Blackburn ACJ40 – Frequently Asked Questions
1) Does the Blackburn ACJ40 splice meet ANSI C119.4?
Yes. The ACJ40 is built to ANSI C119.4, the standard covering connectors used with aluminum and copper conductors in underground and aboveground applications. That is the spec an inspector or utility engineer typically asks for on a compression splice.
2) Can I install the ACJ40 with a wrench, or do I need a compression tool?
This is a compression connector, not a bolted or set-screw type, so it has to be crimped with a hydraulic or battery compression tool and the correct die. There is no mechanical tightening option on it.
3) Is the ACJ40 splice insulated, or does it need taping after crimping?
It is a bare compression barrel with no insulation on it. Any insulating or re-jacketing at the joint has to be done separately with tape, a cover, or heat shrink suited to the circuit voltage.
4) What is the difference between a tension compression splice like the ACJ40 and a standard splice?
A full tension splice is rated to hold the conductor's mechanical pull, which is what you want on overhead or spanned aluminum runs where the cable carries load. A non tension splice only makes the electrical connection and should stay in a box or duct where nothing pulls on it. The ACJ40 is the full tension type for 4/0 aluminum.
5) Where is the Blackburn ACJ40 made?
Mexico. The manufacturer part number is ACJ40, which is the number to quote on a submittal or when matching what is already installed on a line.
