There are many factors to consider when choosing cable
size .nd I will list just but a few.
1. You need to know the kind of load.
2. you need to know if its undergrond, overhead, in or out
doors
3. You need to know the temperature of your environment.
4. You need to consider the atmospheric pressure
With these and other facors you multiply them, depending on
your installation rules, to get a k factor which will then
depend on rated current carrying capacity of the cable at
hand.
