For safety, he said, it is a requirement.
He found it hard to believe Jayco didn't hook up the ground.
Maybe mine was just forgotten at the factory. Anyone else not grounded?
I would be very careful about connecting the inverter's case ground unless it is run through an automatic or manual transfer switch, that isolates the inverter from all the 110VAC electrical connections. The shore power neutral is connected to ground but the stand alone inverters neutral is isolated from ground as designed.
Inverters, like those used in RV's have CGFI built into them (not sure about those cheap store bought ones made in China) and do not need a ground. The cases are double insulated so as to prevent shocks. They are designed for stand alone use, with no connections to the grid. So when you connect the RV to shore power (and you wired in a ground connection to the inverter) you would be altering the electrical layout and could cause some unexpected problems.
I do not have my inverter tied to ground and have no issues.
