I SEARCHED ALOT  TO KNOW WHAT IS THE MAXIMUM ALLOWED VOLTAGE DROP AT MOTOR TERMIANL REGARDING STARTING CURRENT  ACCORDIGN TO IEC BUT DIDNT FIND  

 

IN NEC  5 % AT 1.15  FLC  TEADY STATE  AND 15 %  AT STARTING

IN NEMA 10 %  MAXIMUM ALL CASES   .  

BUT  IEC  I DIDNT ANY RECOMMENDED VALUE

Code only allow 25% of full load amps to get MCA.  It also allow 5% total voltage
drop from main switchboard to end of line (load).  Not allowed more than 2%
from main switchboard to panelboard and not allowed more than 3% from panelboard to end of line (load).
If IEC means international electrical code, california states use only CEC 2013
and NEC 2011.  At any rate NEC 2011 is also International Electrical Coce series.
sorry my friend i didnt understand what you mean by MCA  ؟؟
WHAT YOU SAID ABOUT THE VOLTAGE DROP IS IN THE STEADY STATE
I NEED  THE ALLOWBLE VOLTAGE DROP AT STARTING CASE  
IN NEC ITS 15 %  HOW MUCH IS THE VALUE IN IEC ?
IEC  IS THE INTERNATIONAL ELECTRO TECHICAL COMMITTE
 MOSTLY IN EUROPE COUNTRIED AND MIDDLE EAST WORKING WITH THESE STANDARDS
