I am confronted by people with experience in using them for lighting circuits and sockets in a three-phase installation, as it is only allowed to assemble in an electrical panel four-pole differential switches and one cannot assemble single-phase switches for the protection of sockets or of the lighting for each individual room, that is, say experienced people, it is necessary to install in the electrical panel, only four-pole differential switches, but when an incident occurs, that four-pole falls and the people in that house remain in the dark or with absolutely no energy electrical. That's why I go over the imposition with the tetrapolar and only add a single-phase differential switch, one for each room or 2, one for lighting and another for sockets, especially since the sockets will also be used for electric heaters when there is no gas in the winter due to technical problems which can last more than 2 days and then, each room has its own differential, one for lighting and one for sockets, thus ensuring uninterrupted electricity on the whole floor or even in the whole house. Of course, these differential switches are fed from the three-phase Barament after the Tetrapolar Switch (non-Differential) on each floor. And now I ask: is it correct or not and why is it not correct, please?
Even if the house has a swimming pool and pumps and video cameras or even home automation, only a Tetrapolar Differential Switch is required. I know that only a Differential Switch is necessary for human protection, but for the comfort of the residents, I install Differentials for each room.
