My brain hurts.
The description of your problem is poor.
Do you have a single 80KVA three phase load or (3) 80KVA single phase loads
or a single 240kVA three phase load?
Is your single phase loading connected A-N 34kVA @120V and C-N 41kVA @120V or is it a 34kVA @240 connected A-C and 7kVA C-N at 120V or 68kVA @240V connected A-N-C and 7kVA C-N at 120V?
