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 ??
