I wanted to connect the house to the 1f generator. There is a 4-pole switch network-0-genset. The generator is grounded. An electrician came and stated that he would not bridge 3f to one (in the case of connecting the generator) because the 3-phase differential would not let it pass. I read on the net that the differential balances the amount of input and output current. Reacts in the event of a shortage (leakage) regardless of whether the phases are different or not.
Please give me your opinion.
edit. below is a diagram. I hope it will be readable - I did in Word.
