I pride myself on my electical knowledge but this one is new to me
The meter shares a Square D box outside which serves as the main 200 amp disconect. It has space for maybe 10 breakers. It is grounded to a ground rod or building slab at that point (can't tell where the wire goes without digging) It has one 20 amp installed for an outside non GFI receptical. It is not GFI receptical.
About 50 feet of cable later another Square D box is mounted in the garage with about 20 breakers (one slot not used) no master disconect.
In my mind this is a sub panel for grounding and neutral separation thus a separate ground wire must go to the outside box or to ground.
If they had not put in the one 20 amp breaker in the out side panel the inside box could have been the main with the neutral and ground commoned.
The house is in a new gated community about one year old and the rest of the homes look like they have been wired the same.
Boy do I need spell check back on -- Help
