Europe's RV's

This might help.

RoyB, I think the Europeans have updated things like we have here in the US in that amount of time.

We manufacture electrical items that we ship around the world. All of our European products have at a 3 prong connection.

MM.

The Europe Standard AC VOLTAGE is 220VAC at 50Hz where ours is 120VAC at 60Hz.

All of the plugs I ever saw in Germany when I was there in the late 50s in the Air Force were always two prongs which means they possibly do not have a common ground requirement like we do here in the US. I never saw plugs over there like we use here... We always had to have a step down transformer to use our 120VAC items and some things did not like to see their 50Hz sinewave as I recall...
