For an Energy management system to "SEE" 2 legs, those legs must NOT be on the same "Phase" from the electrical supply. Since you are combining 1 phase of the supply (The Y), That is why your EMS system (any EMS system) does NOT sense and show separate power on each leg. 30 amp service is on 1 phase/leg. 50 amp service is on 2 separate out of phase legs.
