George, GREAT QUESTION but I cant answer it here, its much more complex grrrrrrrrrrrr
The Utility DOES NOT use mother earth as a normal routine "conductor" in the ordinary sense, they have the aerial or buried wires for that. The purpose of mother earth grounding is for lightning and surge protection and to stabilize the entire grid at one common low voltage reference MOTHER EARTH, in a limited sense you might call that a "conductor" (for surge and lightning at least) but I'm sure you see the difference, you're pretty sharp in this electrical business.
On the grids HV Primary, at every few poles the Neutral is mother earth grounded,,,,,,,,On the LV Secondary at the utility transformer the Neutral is mother earth grounded,,,,,,,,,,,At the incoming service to your home Neutral is again mother earth grounded ALL TO KEEP THE GRID AT EARTH REFERENCE AND PROTECT AGAINT SURGES AND LIGHTNING STRIKES
YOUR RV QUESTION Butttttttt George, they are indeed GROUNDED as NEC and OSHA required just NOT to mother earth !!!!!
An RV Generator is wired and configured as a "Separately Derived Source" and requires its Neutral be bonded to a GROUNDING ELECTRODE. Since it wouldnt be too handy to drive down the road attached to an earth ground rod, other permissible Grounding Electrodes (such a iron frame buildings structural steel) suffice. On the RV when youre on genny power and NOT wired to the utility there still needs to be "single point grounding" and Neutral bonding so the RV frame suffices. Even on utility power in a steel frame building the steel can serve as a Grounding Electrode.
In accordance with OSHA and the NEC (NOT me remember) if you use power tools fed from onboard genny receptacles correctly configured and wired YOU DO NOT EARTH GROUND BECAUSE IT CAN INTRODUCE AN ELECTROCUTION HAZARD
BUT LAY PERSONS (heck even some trained electricians and professionals lol) HAVE A HARD TIME UNDERSTANDING THAT ONE AS MY RESPONSES BELOW INDICATE ACTUALLY AS THE OSHA ARTICLE DESCRIBES, EARTH GROUNDING COULD GET YOU KILLED, BUT SOME NON TRAINED GENTS WILL STILL DO IT grrrrrrrrrrrrrrrrrrrrrrr
Take care George, sorry I cant teach here what it takes years of study to understand BUT I DO TRY !!!

Today's Featured Article - Restoration Story: 1951 Farmall H - by The Red (John Fritz). I have been a collector of Farmall tractors since 1990 when I first obtained part of the family farm in Eastern Indiana. My current collection includes a 1938 F20, 1945 H, 1946 H, and the recently purchased 1951 H. This article will focus on what I encountered and what I did to bring the 1951 NEAR DEATH Farmall H back to life.
