the earth has an infinite capacity to absorb electrons.
2. "You would hardly feel a shock"
3. Power is flowing through the meter. Yes, but really not very much. 120V times microamps.
4. "...back to the place it came from, ground."
As for code violations, I did not see any, assuming that there really was a service neutral in that panel (and it was not a subpanel requiring separate buses.)
The error in the video is that the current flows thru the load and back to the lowest potential which
is the neutral of the supply (pole) transformer, not the ground conductor. The neutral conductor is grounded for personnel safety as mentioned when a hot wire touches the enclosure or any metal surface of the load. Under normal conditions current does not flow in a ground conductor. Under fault conditions current flows in the ground path back to where the neutral is grounded into the supply transformer winding. The video never mentions the return back to the transformer neutral.
This guy says it in his comments below the video.:

this is COMPLETELY INCORRECT. the two wires in a single phase circuit both supply and return electrons in alternating directions. that is what ALTERNATING CURRENT does. the reason there is a difference between the SO CALLED hot wire and the SO CALLED neutral wire is because the neutral wire is connected to the earth to protect against overcharges from static and lightning. the electrons DO NOT NORMALY TRAVEL IN THE EARTH AS PART OF THE CIRCUIT!!!!!!
All correct!
As for the violations, look closer at the panel he takes the cover off
Ok, I missed it too.
It is a subpanel and not a main so the neutral landing should not be grounded.
The neutral should only be grounded at one place: the service entrance. Especially
when GF protection is employed.
Good to know. I was afraid the earth would eventually get full:lol:
And what solid evidence do you have that it is a subpanel?We have a winner! Also note the bond screw (green) at the top. And to be honest #8 NM looks a tad small here for all the outgoing circuits.
And what solid evidence do you have that it is a subpanel?
Couldn't the bare wire coming in at the top be a GEC rather than an EGC?
The panel itself appears to be configured for use as service equipment with the buses on either side joined by the heavy metal strip to which the neutral is landed. I will have to go back and see IG there is any sign of a separate ground bus.
