GOOD AFTERNOON. I HAVE A CALCULATED CONSUMPTION HOUSING OF 53A. THE CONNECTION MUST BE THREE-PHASE, BUT I HAVE NO CLEAR HOW TO MAKE THE CALCULATION FOR THE GENERAL CONDUCTOR (FROM THE METER TO THE BOARD), AND THE THERMOMAGNETIC WRENCH. I WANT TO KNOW IF THE FOLLOWING FORM IS THE RIGHT: - CALCULATE AMPERAGE BY CIRCUIT. - EQUITABLY REPAIR CIRCUITS BY PHASE. - TAKE THE HIGHER LOAD PHASE TO CALCULATE THE DRIVER AND THE GENERAL THERMOMAGNETICS. IN ADDITION, DO I HAVE TO PLACE A DIFFERENTIAL CIRCUIT BREAKER IN EACH PHASE, DEPENDING ON EACH DIPPER OF THE PHASE AMPERAGE? IF ALL CIRCUITS ARE SINGLE PHASE, WOULD THE CIRCUITS BE BIPOLAR EVEN IF THE GENERAL FOOD IS THREE-PHASE?
