It all hangs on where your grounding terminates... in the panel or in your disconnect outside (regardless if that disconnected in the meter or not)why is it so complicated either you have to separate or you don’t
The panel inside is literally 3 feet away it’s not a sub panel
If you ground everything inside, that is your service disconnect, and the disconnect outside would be your emergency disconnect.
If your ground everything outside, then that is your service disconnect, and your panel inside becomes a sub panel.
What makes it complicated is when there is a "half here, half there" approach on the grounding. Water ground inside, ground rod connected outside... I don't like that approach
It doesn't matter if your panel inside is piggybacked on the backside of your outside disconnect, with only 18 inches of cable. If it grounds outside, then your inside panel is a subpanel
