It is a good question. The question of such standards came up when we
discussed the Low Voltage Mains concept in an earlier post here. My
conclusion was that it is best *not* to expect *any* standards but
rather allow for adapter leads and converters as needed. Not ideal but
it seems that it will always be that way.
