How to calculate the voltage drop of 4 Core 50 Sqmm SWA
cable for a distance of 350 mtrs and what can be the
maximum load connected to it?
Answer Posted / sudhakar g
According to Polycab standard the current carrying for 4C 50Sqmm STEEL WIRE ARMORED cable is 133A(ground) and 142A(air)
The formula for voltage drop is
Vd=(MV*Id*L)/1000
