I recently had an inspection at a new county i haven't worked at and was told that i cant have metal “pipe hangers” on a pvc conduit (i had my guy use the hangers to give it a bit of offset so it can connect to the disconnect easier) this is my first time running into this problem as I didn’t think it was a problem since the conduit is plastic. The county is Anne Arundel county in Maryland and they still use the 2017 NEC book, if anyone can help me locate what article talks about this issue id greatly appreciate it.
