I currently live in Norway and purchased 4 major appliances, Electolux dishwasher, washing machine, stove and a Bosch refrigerator. Will therse work when I move back to the USA? If so, How do I convert the electricity(voltage) and what about the dimensions fitting into an American kitchen (stove and dishwasher, in particular). Any ideas?

Only an electrical pundit myself but I believe you can buy an adaptor for the US. I've taken a few things like this apart in the past and for a more permanent solution I would think that you would be able to have the appliances cheaply rewired at the power point when you move back to the US.

Would it not be more cost effective to sell these items and purchase new in the States? I would think the cost of shipping back would make it more economical. Just a thought
