How to connect heating elements in a three-phase network if there are 3 single-phase RCDs?
The network is three-phase, on each phase there is an automatic machine and an RCD. I want to connect a ten (star), on it the zero N is already combined. Is it possible to combine zeros emerging from an RCD? Or do you need to separate zeros from each other on a shadow?
Thank.
Hello! It is impossible. There may be false positives. Buy a three-phase RCD or separate the zeros of the Tenes from each other and connect them as if they were three independent TENs, if possible, of course.
