As far for 3 inch PVC , EMT , Ridge conduits the outside diamiter is the same so it will work either way.
As I did one with EMT to Ridge conduit with compression coupling and I have no issue using that one however make sure keep the inside the conduit deburred good.
I know as above posted as I mention I don't see major issue beside the termail adpator is not there and not using proper coupling due the width of wall per photo due it is a 2X4 wall if it was 2X6 then it will have no issue using proper TA on it.
I am not sure either you or other person mention about the EGC clamp they should used a acorn clamp on the rebar.
{ I know in state of wisconsin do allow rebar used for EGC for new construction only not with addtion building unless you have steel structure. in France it kinda toss up with it }
Merci,Marc
