Hi frnds :)
plz tell me that i have 100 KVA 3 phase generator so by
thumb rule 100*1.4 = 144 amps
and generaly we can operate at 80% load...so it will 144*0.8
=112 amps....
so now i m confused about single phase load.....if we use
that generator only for single phase the that 112 amps is
total single phase load or i can give 112 amps at red 112
amps at yellow and 112 amps at blue....
i mean that total single phase load that 100 KVA generator
will take is 112+112+112=336 amp ??

No You cannot take 112 amps in each phase. you can take 112 amps in the sumation of r,y and b phase. (ie)total load current = Rph + Yph +Bph current.

Current in each phase 112 A ,ph voltage say 230 V. Then
apparent power in each phase is about 26 KVA .Sum = 78 KVA
which is almost the permissible load on the gen. If you add
phase currents ,the resultant is zero as they are vector
quantities . You can have a load of 112A in each phase .
