Note: A) As per above calculation, the Cable Size of
1 R-
3cx25 Sqmm is found to be OK.
B) In above calculation, Consumed Load have been considered as Motor rating. C) The above cable size selected for motor is based on Average length of 150 Mtr, However, the final cable sizes for individual motors shall be based on the actual cable lengths considering the voltage drop.
