Answer / sameer
First covert kw to kVa kva = Kw / PF(0.8)
Rated full load current in A = (Total connected load in
kva / sq.rt * 3 x Supply Voltage) x 1000

Answer / jaimin
FOR 3 PHASE CKT
KW=ROOT(3)*V*A POWER FACTOR
A=KW/(ROOT(3)*V*POWER FACTOR)
FOR SINGLE PHASE CKT.
KW=V*A*POWER FACTOR
A=KW/V*POWER FACTOR

Answer / harish
KW is always a real quantity and hence we do not
require any power factor term...simply divide he given kw
by the voltage and you get the required amperes...

Answer / riyadh
we know load watts , u apply below formula for 3 phase &
single phase
3 phase I = Total load in watts/3*220V
1 phase I = Total load in watts/220V
