In Pa. we have a catch all law called risking a catastrophe.
and if he did put such a board in service and it failed  and caused
major damage ,injury or death he would be facing felony charges if AHJ
so desired.
This law also effects professionals who fail to notify or otherwise
fail to stop a problem from happening that is with in there power.
So yes it is other peoples buisness who posts what on this board .
So as a professional I posted the approriate response with out getting
nasty.


I still repair industrial electronic boards mostly power supplies  for
equiptment no longer made or supported but nothing which is lifesafety
oriented or would pose a hazard when it fails.,
