In the link for the Link it shows the yellow wires going to each gen's chassis ground lug.
How does the chassis ground for the gen connect to the gen's receptacles' neutrals by using the bonding plug unless the gen's chassis is connected to the receptacles' grounds?
Is that what wnjj meant above?
My B&S P2200 portable inverter gen manual says, "--the AC stator winding is isolated from the grounding fastener and the AC receptacle ground pins. On a floating neutral generator the AC receptacle ground pins are not functional. Electrical devices, such as a GFCI, requiring a functioning ground pin will not operate."
