I’m looking at the grounding system on my new house and it just does not look right to me.
320 Amp service. As I understand it, the meter base will be wired to a 200 amp panel in the garage, and a nearby 200 amp disconnect. The 200 amp disconnect is wired to a 200 amp panel in the “unfinished basement” – which is actually just a really tall crawl space with a concrete floor.
Three ground rods and a ufer ground. One ground rod connects to the 200 amp panel in the garage, one ground rod connects to the 200 amp disconnect, and the third ground rod attaches to the 200 amp panel in the crawl space. Both 200 amp panels have the ground connected to the neutral.
The meter base and the 200 amp disconnect are not in place yet, and the ufer ground isn’t wired yet.
My understanding is that all of the ground wires should connect to one panel, and that is the only panel that should have the ground and neutral connected. This obviously isn’t wired like that.
