I am pretty sure that it is not allowed but I can't find where it says that type SE or SER cable cannot be installed in conduit for a complete run of say...60 feet.
I have to inspect a job that my electrician wannabe brother-in-law did where I know that he installed two 200a subfeeds in a small garage in PVC conduit using SER cable (4/0).
Anyone I know would have used THHN and it would not be an issue but he doesn't know any better.
Help me justify failing the installation or tell me if I'm wrong.
