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 ??

protected.Can any one help me to get out of this.how should
i reply on basis of some great comparision and calculations.
Please help
