[QUOTE="boltonsparky, post: 500045, member: 4678"] I understand it with generators (or I think I do) when you have cables, FDUs etc. in soggy fields but with a van and inverter setup if the whole van body went live from an inverter inside the van if you stepped out of the van and touched the ground whilst holding the metal bodywork nothing would happen because the van is insulated from the ground by the tyres so there isn't a return path from the outside ground back to the neutral of the inverter so no current could pass through your body. Hammer in an earth rod though and there is now a path back to the neutral through your body and the earth rod (via the neutral earth link at the inverter), probably a high resistance one as the earth rod is likely to be poorly installed so an amount of current is likely to pass through your body but with it being a high resistance path would it be enough to trip anything?
