how choose conductor &caple&wire depending upon the load

Answer / ccic
Cable/wire , i.e. the conductor should be rated for at
least 125% of the FLA. The upstream CB protecting this
conductor should also be rated similarly, i.e. for a load
with 100A as FLA, the cable should be able to carry at
least 125 A. The cable derating factors (type of cable,
type of installation, ambient condicions, Voltage Drop etc)
should then be used to select the ACTUAL cable. The CB
should be rated for 125 A (Instantaneous Trip setting)

Answer / k.p.sharma
Size depends on two things
1. Current rating normally load current should be 70-80% of
cable's minimum capacity.
2. Voltage drop should be within limit i.e. for lighting 3%
and for motor during starting within 10%.
