That is how I see it. 22 years Naval experience living in a steel pipe (submarine) for 10 of them. The neutral & ground were bonded in that environment.
Retired 24 year submariner here. Generated lots of electricity on three Nukes and two Diesel boats.
UNgrounded three phase 450 Volt power on the Nukes,
UNgrounded DC on the WWII Diesel Boats. Spent many hours and more hours chasing grounds.
"320-1.2.1.1 System Grounding. All ac distribution systems on U.S. Navy ships are ungrounded." ...
"Ungrounded electrical systems have no intentional
connections between the electrical conductors and the ground (ship’s hull). These systems were chosen for their
higher reliability because grounding of a single conductor will not typically produce enough fault current to
interrupt power. Grounds must be removed as soon as possible to maintain this advantage, however, because a
second ground on another phase will cause a power loss and could endanger personnel."
Additionally, at a 110V Shipboard receptacle the ground connector is connected separately to the hull and is not "bonded" to the other two connectors.
While I do have an opinion, I have zero RV experience and thus no standing to weigh in. However, I could not allow a mistaken Submarine reference be introduced into the mix.
