Hi,
I am planning to set up a vacation home with several friends in Europe where the voltage is 220/240. Since we have a lot of 110 v appliances that we can bring over, I have checked the wiring of the property and the receptacles have 2 hot wires and an insulated wire for grounding. It is connected to the bus bar of the main panel and the pole transformer of the utility shows a center connection that enters the bus bar of said panel. The same busbar is then grounded with ground bars. I know that the old NEC code allowed for the dryers to have a 3 prong receptacle with an insulated wire serving as both ground and neutral. I also know that article 250.140 of the NEC, allows for the use of the 3 prong wire still where the receptacle in the house is 3 wire. As such I want to cut off the receptacle of the 110 appliances, and wire one hot wire to a spade and the neutral to the ground pole of the new receptacle to obtain 110/120 volts. Testing shows I get about 117 volts from said connection. If I do this I can plug the 110 and 220 volt appliances without worrying that the 110 appliance will burn if inadvertently plugged to a 220 outlet. Is there anything else, I need to be concerned about?
Thanks
