I had a 200 amp panel main panel missing a ground wire. The main panel is attached to a Generac subpanel in which all the ground wires were exiting. I could see a 12 guage ground wire bonded to the ground bus in the main panel lead to the bridge to the Generac subpanel/
Is this proper? Any thoughts on this would be very much appreciated. I’ve attached a few photos
Is it a portable generator or a standalone generator? Can you show a picture of the interior of the generac panel?
It’s hard to tell anything from your photos, the “12 gauge ground wire” sounds unusual.
Do have any better photos showing the overall configuration/closeups of critical points?
Isn’t the transfer switch actually the service disconnect and the panel the sub-panel? More clear photos are needed.
Agreed…
Agreed. I don’t think I’ve ever seen a Generac switch as a sub-panel, they’re always the service panel. And those pictures are really terrible, I hope they weren’t in an inspection report.
From the simple basics that I understand, A Generac panel is nothing more than a generator transfer switch. It is not considered a subpanel.
A GENERAC panel, manufactured by Generac Power Systems are designed to switch power between the utility company source of power and a generator.
A subpanel is a smaller electrical distribution panel drawing current from the main electrical service panel in a home, or in a building.
Robert M. would be the best person do draw advice from.
Is this proper? You images do not allow a proper hypotheses.
Next time provide clear image subjects that focus on your concerns.
As for the ground,did you look to see if service equipment enclosure was bonded to the conduit?
I am use to seeing a separate panel for generators with much fewer breakers due to the limited power the generator provides.
I understand the logic but isn’t the first disconnect or main disconnect considered after the utility meter or the last disconnect downstream?
Thoughts? Slow down, you move too fast, you got to make the moments last Relying on body cam footage because you forgot to take proper pictures. Start out from the panel, get your lighting right, then take additional pictures increasingly close, finally focusing in on the issue you hope to describe.
Thank you all for your responses. Indeed the original photo’s were from a body cam. I’ve attached more clear photos as requested.
Thanks for the additional photos. So now that we’ve seen the new photos we know that the ATS is the service disconnect and the panel is a sub-panel. How does this relate to you initial questions?
Thank you for your response. This was very helpful. FYI, I"m currently studying to become a home inspector and have not gotten my license yet and this was the first time I saw a Generac system configured as the main service disconnect with the main panel acting as a subpanel.
You’re welcome. 
There are several members here who can help you with technical electrical questions. Don’t be afraid to ask.
Follow the equipment grounding conductors of the individual circuits at the top panel. Also the feeder EGC coming into the subpanel at the bottom. There should be a grounding bus bar hidden behind the wad of conductors at the right side of the open subpanel, so you shouldn’t be missing grounding
