Hello everyone. I recently went to a mobile home/RV park where the utility supplies their own 200 amp mobile home services/meter combos. The utility installs these combo units to the pole and blanks out the meter bases until we get in and install the RV 50 amp receptacles and service grounding, then call for inspection. The utility does not provide grounding themselves. So, while I was installing the wiring to one of the units, my sweaty arm touched the side of the enclosure and I felt a nice jolt. I was working on the load side of an opened 200 amp breaker so it wasn't that I connected a conductor incorrectly. I continued connecting the unit (with gloves) and when I was finish, I drove two ground rods. The first ground rod went in with no issue connecting the grounding conductor but when I tried to connect the grounding to the second ground rod, there was a visible arc. I then became reassured there was voltage on the grounding system. I pulled out my meter and there was 78 volts on the ground rod ( which is terminated at the source neutral bar in the service enclosure). So, am I correct to assume there is stray voltage on the neutral, from the utility line? What could (likely) cause this? Thanks
