More data. The electric showers here in Brazil sometimes use 8,000 watts or even more. There are two poles: one is + and the other is "neutral". The neutral is grounded at the entrance of the house (the panel). In this way the whole house is grounded there.
The showers are made of plastic but some are metal. They have three wires, one of them is the ground. They connect this ground to the neutral pole (ground) but some electrician say that they don't have to be connected noweher because there is already a neutral, ground pole...
I think I am going to put a rubber mat on the floor...
I also notice that when left on for long time the wires get a little warm...
What do you all think?
