Hi Dave
Sorry, but I do not understand what you are trying to say.
Your statement seems to contradict it's self
Core balance RCDs are the approved type FOR fitting to generators in As
Mains supply also use core balance RCDs
The RCDs fitted to vans .motor homes etc are the core balance type.
RCDs do not need to have a connection to the mass of earth to operate,in the portable situation"an earth is neither required or recommended" by Aus Standards
The frame of the van etc is the effective earth
The system relies on the wiring earth between generator OR inverter & the load [a frame to neutral earthing system in simple words]
It is simply because the power from the generator IS NOT M.E.N.ed, that an earth stake is not required & it is not desirable to make a small portable generator supply M.E.N
In fact actively discouraged by all Ausstate regulations.
we are not talking about generators permanently hard wired
