Looking for a direction on this one. The main disconnect is located outside below the electric meter. The main panel is located inside and also has a main breaker. The exterior disconnect has an enclosure ground. The inside panel doesn’t. The inside panel has a 4 wire feed, (which I rarely see here) coming from the exterior disconnect. In my mind the interior panel is a sub panel and the grounds and neutrals should be separated.
Am I correct on this or should the interior panel have its own ground rod and have the grounds and neutrals bonded?
Thanks in advance
