A 1000/1333KVA 4160-208Y/120V transformer is feeding two service switches, and each service switch is feeding a 2000A rated switchboard SSA-1 & SSA-2.
What I see as the problem is that max power available if S-SW1 and S-SW2 are operated in parallel is 1008 kva or 1,400 amps at 120/208v, 3p.yet boards SSA-1 and SSA-2 are rated at 2,000. I should think if the transformer is fan cooled we could use the 1333KVA rating and get a 1800A but still short of the 2000A rating of the switchboard. Is my analysis correct? Please see attached.
