Can I use greenlee crimps or burndy crimps on burndy dies. I have a ground grid going in and purchased burndy crimps but I have greenlee dies. Any rules on what I can or cannot use
The product standard requires you to use the tooling that is specified by the manufacturer.

Use of specific tools — A specific tool and die used to assemble a wire connector to a conductor is identified on the connector, or on or within the unit container of the connector. The identification consists of a catalog or type designation, color-coding, die index number, or equivalent means. Color-coding of the crimp barrel is common.
