The current capacity or loading of cables & conductors is limited by the thermal, electrical and other associated losses provided by the conductor, insulation, protective covering and surroundings. Thus, the current carrying capacity of cable depends not only on size, type voltage grade, components, material design and manufacturing but also on a number of varied conditions of installation and use. It is desirable to determine the correct current carrying capacity on actual service conditions for each and every case. Any overloading of cables will reduce the life expectancy. At the Same time, under loading leads to uneconomic utilization of their capacity.

Standard conditions of installation:

1) Maximum conductor temperature
2) Thermal resistivity of soil
3) Thermal resistivity of PVC
4) Ambient air temperature
5) Ground temperature
6) Depth of laying (cable laid direct in ground)

Note: For site conditions other than the above standard conditions of installation, the appropriate rating factors given must be used.
