im not an expert on generators ,but am a qualified electrical tester .i would have thought that the output from the genny was floating meaning not connected to earth in any way .That meaning to get a shock you would have to touch both the live and neutral conductors at the same time.which is usually less likely.the only reason we can get a shock from the live conductor in a household domestic installation is that the electrical suppliers earth the neurtral at every substation..with regard to 30 or 100ma markings on an rcd that is the amount of leakage current to earth the unit will trip at.when tested an rcd should not trip within 2 seconds at half its rated current ,should trip within 300ms at its rated current and should trip within 50ms at 5 times it rated current.
