I want formula to calculate cable size as per load given in
kw & amp.I searched many sites but didn't right answer.Plz
reply me asap.
Answer Posted / mohammed motawe
i will give you the basic eqaution,
PL = V*I*Pf=S*Pf ; i need to calculate the load current ,
I= PL/(V*Pf); as per ADDC(abu dhabi electricity), Pf=0.9
V=230 volt,
From the load CURRENT i can choose the rated current of
cable, take into account the voltage drop, so refer to
cataloge of any cables and wires company like oman cables
regarding with three phase just put cu(3) in the equations
best regards
