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 / rajkumar mohan
For simple easy remembering...
Make ur own excel sheet as per below
(its strictly not a technical way)
for Eg:for breakers 10-100 dive the breaker value with 4.5 you will get some value go to thte next cable size
10A
10/4.5 =2.2sq.mm
go to 2.5 sq.mm
--------------------------
you can use this formula till you are familiar with the cable sizes (Y)

need to make a report. Need to choose a 3phase induction motor. Load conditions motor will operate in : Maximum Load: 30 Kw Speed: 2950 rpm Ambient temp: 20 cent Supply voltage: 440V Frequency: 50Hz need to look for the safety factor when choosing the motor, went through catalouge found a few, but dont know how to choose the safety factor allowing an extra load something above 30 KW to avoid any harm.
