Would there be any code violation to use a pole-mounted transformer lug that was listed as such and instead use it for a mechanical connection similar to what would be on the line side of a fused AC disconnect (i.e. mechanical lug)?

If it is listed as a connector I can't see that the nomenclature they are using to describe it makes any difference.

I don't see the UL mark in the picture and the catalog page does not say it is listed.

However, the length of the stud makes me nervous. I suppose you could cut it to an appropriate length. Some might object to that.

Most mechanical set screw style lugs, in equipment, are not rated to clamp down onto a solid conductor of this size.
