1- exchange the box for 32mod - it's not a problem
2- in fact a mistake of 3 differentials if I protect the phases and more differentials if I would like to protect each circuit separately (because I can put even 10 of them on.
3- Will one three-phase differential protect my installation as well as three separate differentials for each phase? Is it about functionality, i.e. a problem with detecting a fault, or about securing the installation itself?
4- is phase control necessary?
