>>"With ALL power DISCONNECTED, measure the resistance between output neutral and ground. you will certainly find it is open circuit.:<<
>>>>>>>>>>That will be the case if they are autotransformers. A test he can do is check continuity from the neutral side of the 120V receptacle and the 220V plug neutral pin. If the transformer is indeed an autotransformer he will read continuity.

>>"The voltage you measure with a high impedance meter is due to leakage currents and is not "real"."<<
>>>>>>>Caution here, if the transformer is indeed an autotransformer the 120V and 220V to earth ground are lethal....
