I inspected a home yesterday and found all recepticals to be properly grounded but when I got to the panel I could not find a ground wire!
The panel had been upgraded.
The cold water pipe was right below it and I could see where a ground clamp had been.
I checked outside and there was no evidence of a ground rod or ground plate.
Service conduit went into the home under the driveway.
I advised the client and suggest an electrician to repair as necessary.
My question is:
Absent any visible ground wire how would the recepticals in the home show a ground?
