I really was just trying to sort it out for readers overlooking this thread so they do not make mistakes. I have read a number of threads on cnczone where they have done just that and fried their VFDs. If anyone is going to read this hopefully they take away that they cannot use Neatral as ground or they will be in violation of the NEC. If my memory serves me well it was in 2005 when this became a code violation.
