I’m sure this has been addressed before but still unclear what to say. 1969 build, single family. Appears to be an upgraded panel in 2012. I know there should be two grounding methods; I see two grounds exiting the panel, but thats it. Couldn’t see any grounding rods. The top bare neutral went into an BX type armored cable. So do I mention that I couldn’t see any actual grounds? “Actual grounding method couldn’t be verified”?
Thank you
The service main has an earth ground. The termination of the main ground wire for the electrical service was not accessible.
So clear and simple, thanks!
Some constructive criticism, you should work on your terminology. The conductors in question are Grounding Electrode Conductors (GEC’s) not “grounds”. The bare conductor in the cable armor is a GEC not a neutral conductor. If there is a metal water pipe that would be a grounding electrode, same for ground rods. Connection to ground rods are not require to be accessible so it’s possible that they’re buried. 
Thank you, you are correct and I appreciate your input.
