***SUPPOSE WE USE COPPER CONDUCTOR AND WE ALLOW A MAXIMUM OF
5V MAX. VOLTAGE DROP:
5= 2*12*15*230/CSA
CSA= 82800/5
CSA= 16560 CM
FROM COMMERCIAL REFERRENCES:
15560 CM IS CLOSEST TO 16510 CM WHICH IS #8 COPPER OR 8 SQMM
WIRE.
NOTE:
1. IN THIS CASE A MAXIMUM OF 5 VOLTS WAS CONSIDERED IN THE
CALCULATION.
2. THIS CALCULATION IS NOT VALID FOR LARGE MOTORS. BECAUSE
MOTORS DRAWS A MAXIMUM OF 7OO% TIMES ITS FULL LOAD TORQUE
DEPENDING ON THE MOTOR CONTROL STARTING METHODS USED BY THE
DESIGNING ENGINEER.
