have a meter base that has a 100amp service disconnect below the meter itself and feeds a 30 circuit panel 277/480 volt 3 phase with 225 amp main lugs.transformer 45KVA primary side feeds a 120/208 volt panel 3 phase and the secondary side feeds a 70 amp breaker for the transformer.I am going to install a 42 circuit panel since we need more room 277/480 volt 3 phase with 225 amp main lugs. will the current set up be sufficient to handle the extra loads or do I need to pull bigger wire so that breakers will not be tripping? any help would be greatly appreciated!!
