Well now we know where your designing it for.
IEC 60906-1 'N' socket & plug wasn't fully adopted in Brazil and as far as I remember there are quite a few variations still in use around the country. I think you are basically on an hiding to nothing here. It looks like Brazil could be like many countries, they seem to take standards from bits and pieces all over, until they confrim a direction they want to go. Saudi are now adopting the European Standard. 380/220 60hz. It is rare now to have 220/127 anywhere. But 20 yrs ago it was a mish mash of standards.
Isnt Saudi Arabia still 127/220?
