The below is a suggestion received & I wanted to hear what the board thought of it ??????
""On your question on how to hook up your RV using your RV adapter. If it is the type of adapter with two plugs, one 30 amp and the other 15 amp, you may be able to get it to work with the GFI outlet at the campground. Remove the ground from the 15 amp plug of the adapter by breaking off the ground prong of the 15 amp plug of the adapter. To use, plug the 30 amp plug into the campground 30 amp outlet, and plug the 15 amp plug of the adapter into the 15 amp GFI outlet of the campground. Make sure the 15 amp plug is positioned as if it still had the ground pin, so the polarity is correct. This is safe as your RV will still have a ground connection via the 30 amp plug.
That should work. Just so the ground wire of the 15 amp adapter plug is not connected to the GFI outlet ground. Make sure to maintain the polarity of the 15 amp plug so the hot and common wires are connected as if the ground pin was there. As long as there is no other problem, this should work.
What happens: If the GFI outlet senses current through the ground terminal it will trip. Having the 30 amp and 15 amp plug connected to the camp's 30 and 15 amp outlets' ground, (via the adapter) the two ground terminals of the camp's outlets will be connected together. There will always be a small current flow from one outlet ground to the other, and the 15 amp GFI outlet will trip. Removing the ground connection will break the contact, and no current will flow from one outlet to the other.""
