Answer / santosh

Cable Sizing to be selected based upon many factors, some of
these are:
1. Total connected load to be considered with 25% spare
and maximum demand current in AMPS to be calculated. This
will be maximum ampacity.
2. Derating factors such as length of cable to be laid,
Type of installation of cable in medium ( In air, Duct,
Directly buried in earth).
3. Thermal resisivity of soil at 2.5 deg C/m, correction
