What a big help. Yes, this is the case: I will have a choice between 220 and 127. And yes... in 127 one pole is + and the other is neutral (ground). Then as you say, if I connect the shower on 220 I will have the two poles hot? Isn't this more dangerous?... I guess then I will have to run the ground wire from the shower independetly to the main panel. The problem is that the main panel is not to close to the showers...perhaps 15 to 20 meters. Will this be OK?... You may wonder why I am abusing your patience on these issues... but I have had so many opinions here... even from electritians...And I want to do the right thing...Perhaps one of these days you may decide to take a holiday in Brazil and take a look...(hope you will take showers...)
