	dear all.. could anyone can help me with IEC/NEC standards on following points related to the cable sizing of 4.16kv motor feeder. Calculations for cable size selection based on full load current, short circuit current, continuos c.c.c, allowable voltage drop at starting and running and limits of maximum cable length. Please specify the code number of standards. Thanks for your support, Jobinjosin

	That's a lot of voltage for a motor. Do you know anything else about the motor than just the voltage that gets applied, i.e. the current rating, single phase or three phase, starter circuitry, indoor or outdoor, above or below ground? I'd also like to know why you don't contact a local electrician? __________________ "Don't disturb my circles." translation of Archimedes last words

	dear all, Let me clear what I am looking for. I know about required parameters and its calculations for cable sizing of motor feeder. but I don't know and couldn't found the related standards with code number according to NEC or IEC. Thank you all for your suggetions and comments. Jobinjosin

	If you need to ask here, then don't do it over there.
