Hello, for a 3-phase installation (5x2.5) I want to connect a plate, a dishwasher and an oven under 230V, I have already pulled two 230V sockets from two phases and now the question of connecting the plate appears. Can one blue wire play the role of N1 and N2 with the two-phase option? Two cables from the board connected to it. Another question is whether with such a cable on the installation I can replace the fuses from 16A to 20A? After all, the load will not be constant. Can it connect the board normally to phases 1, 2, 3 and add 230V sockets to 2, 3?
