As noted in Post #2, the installation is in violation of 240.8.
I agree with this. The circuits are clearly parraled and a violation. If you think about it when the ATS is on utility and power is being used in the house the current if flowing through both panel breakers.
Depending on the arrangement of the condcutors on the load side of the ATS, it may also be in violation of 240.21.
I'm not sure about this... could you elaborate?.
