I clearly selected the cable according to the current carrying capacity
If so, reduce the current carrying capacity. Is it in a conduit, cable tray, or directly buried? Different laying methods have different coefficients. How many cables are in the same bundle/conduit?
Cable Tray Raceway Fill and Load Calculations
Cable Tray is sized based on the number and type of cables required for the current and future need. A 50% fill ratio should equal the maximum number of cables pulled in a given cross section.
