OK, Let,s add some more info to this story. I was told that you can't get 400 amp 3 pole breakers for this panel anymore since it was a custom made panel. ( I wanted to see this backed up with a letter from the manufacture.) Would we accept a "Variation" to the code here and allow a custom made tie handle. Here in NJ we can allow "variations" if the AHJ feels that what is being offered is safe and hazard free. There is no UL listed tie handle as of yet, but that is why the contractor would try to get a custom made tie handle.
