I took the covers off my panels. My setup is a little more complicated than most because we have a generator with an automatic transfer switch. The electric service enters the generator panel. The generator panel feeds the main panel.
I am reasonably certain that I don't have a ufer ground. In the main panel there are two grounding wires:
- One coming from the generator panel
- One exiting the main panel and attaching to my water main
Inside the generator panel:
- I can see the ground that connects the generator to the main panel
- There is another ground that exits the generator panel through conduit that goes to a shutoff switch box on the OUTSIDE of my house.
Inside the outside switch box:
- The ground from the generator panel is connected with a nut to another ground.
- The connected ground goes into my generator via a conduit.
I can't see any visible indication around the generator that there is a wire exiting it into a ground rod. The only possibility would be if there is something penetrating the concrete slab the generator sits on.
It looks like it would be fairly simple to add a ground rod and either tie it into the ground that is in the outside switch box, OR do that + have it be a continuous wire that routes into the house and connects to the generator panel and main panel.
I'm going to call an electrician. It really seems like my house isn't properly grounded, but also looks pretty simple to fix. Any further advice is greatly appreciated!
