Thanks for answering guys.
Apparently the neutral cable that communicated the 3 shots was wrong, when I checked it well, now with better light, the places that seemed worn, were like "burned" when I remembered where they came from (and as is provisional what I am doing until past the parties and put in order) were some wires that are inside a corrugated sun exposure, the corrugated for years "cracked" in some places and in those places the sun "burned" the filaments were not seen, but if the cable was rough-dry like elephant skin.
I connected another cable to test (a new one of 1.5 mm) and there was no load in the sockets, or neutral cable tip, I think that cable was the problem, in the afternoon I will put 2.5mm.
Elektomaq, when I left only the Phase cable, in the "rush" from the thermal of the piece to the junction box for the tap boxes, it was to clear me of doubts that in that section (thermal-junction box) when not being the neutral cable, the problem would be from the section of the neutral cable that communicates the boxes of the 3 sockets, which would then be attached to the neutral cable (which was not) of the "connection"
I also remember once I rolled a parallel cable, and the neutral one gave voltage in the pager, unrolled it and no longer used any more voltages, I checked it well to see if it was broken, or touching some hair, but no ... it was fine, until now I thought it was induction, and that's why I thought the same thing now.
Again I changed an outlet, with a double key that was good, but the frame was half broken, I put another used one but the frame well, and the neutral of the socket marked me voltage, I changed one socket for another used one and it was already well .. .obviously checking, re-pulling, putting the cables, etc ... and it was the socket
Hello guys again: I solved the issue of voltage in the neutral, as I said before, I thought they were the wires, but the solution was so silly ... but hey, you learn from mistakes.
It turns out that when I put the wires in the sockets, phase and neutral, to "make faster" the thermal only connected the phase, leaving the neutral unconnected in the thermal, thinking "the charge is the phase, I go with the Buscapolo, I touch the contacts, and the phase must give load, and the neutral does not, whether it is connected, or not "... err that I had almost a day testing and testing, changing cables ...
I had done a test at noon with another neutral cable, and it seemed solved, at night I connected it, but again to gain seconds of time ... only in the thermal connected the phase, the neutral connected to the sockets, but Not in the thermal. and still giving voltage in the neutral ... I wanted to kill ... then I connect the neutral to the thermal ... and the neutral no longer gave more charge, there already everything was fine, and that was the error, not the wires. .Without leaving the neutral in the thermal plug unconnected, and it seems that the neutral wire inside the pipes was induction despite not being connected to the thermal
