Inspected this panel today. Did not appear to me to be grounded. A problem I commonly find in Florida is the ground is often tied to the rebar in the block walls and not visible unless it is on a cold water line outside or a ground rod in the ground. Sometimes all I have to go by is finding a grounding conductor in the panel. This photo is a shot of the left side of the panel with the neutral bus and the ground bus shown. It would appear that the empty screw where the grounds are tied to should have a large gauge wire running to a ground. Correct me if I am wrong but I do not see anything on this that would look to be a qualified grounding wire.
Thanks guys, yeah Ufer grounds are common here. I have found a few panels grounded here with just a 12 or 14 awg wire tied to a ground rod on an upgraded panel, usually the green wire green, that is what I suspected here, but more than likely 1 or more of those 3 aluminum wires are the ground.
What do you mean “that lax” Jim? If the house is reinforced masonry construction and the grounding wire is tied to the rebar between the concrete block walls, what do you want me to do, get a demo hammer and demolish the wall to find the ground connection? I always verify the grounding connection, if it can be found, but as I said, with reinforced masonry construction, the ground is usually tied in between the wall, not much I can do but note on the report that a ground connection could not be seen and defer to an electrician.
