The service equipment for a townhouse I inspected was oddly grounded, with a grounding wire observed from the distribution raceway where the main incoming service wires branched off the meters for the individual units, but no dedicated grounding electrode at all for the main panel or the meter for the unit (evidently the rightmost meter).
The exterior grounding wire is just left of the conduit on the top 2 pictures (between the conduit and meter on the top picture).
There were other issues observed which were obvious enough, and need not be addressed here.
The panel was wired as a main panel, rather than a sub-panel, so I expected to see a dedicated grounding electrode for the unit.
The grounding wire below the point the main cables entered the wall was evidently for the panel in the adjacent condo.
In any case, the panel obviously has no supplemental grounding, But does the main service grounding electrode configured in this way provide good service grounding?
