The issue of parallel came up when the original EC decided to run (2) 2 1/2" conduits instead of a 4".
The city plan reviewer told me to have the PE draw it accordingly.
However, the PoCo requires a minimum 4" for a 3-phase 400-amp service, so I have to remove the original pipes and replace with 4".
The Engineering Firm is from out of state and works for the "Family Dollar" store corp. and will re-draw the service based on whatever is required by the locals.
As far as the load calculation, remember it is 3-phase Delta, so 85 kva is only 205 amps at 120/240.
