Aluminium & Copper Current Carrying Capacity Calculation

Cable current rating calculation. The current ratings are selected from Tables 4 to 21 in AS/NZS 3008-2017. It is based on cable type, insulation type and the cable installation method. Tables 4 to 21 are based on an ambient temperature of 40°C and a ground temperature of 25°C. The cable sizing calculator supports the following conductors. * Current ratings based on 75˚C conductor temperature, 25˚C ambient temperature, emissivity 0.5, 2ft/sec wind in sun. ** Resistance is calculated using ASTM standard increments of stranding, and metal conductivity of 61.2% IACS for EC (1350) and 8% IACS for steel

From the chart, the proper cable size to select would be #2/0 cable. Cable sizes are increased for longer lengths primarily for the purpose of minimizing cable drop. For higher current levels, two or more cables are often recommended and should be hooked up in parallel or together in order to share the current load The harder the copper (or aluminum, etc), the worse it becomes at carrying a current. This comes into play as the metal is hardened by rolling, stamping, bending or hole punching. The material around these bends and holes becomes work hardened, and the increased resistance will skew the estimations provided by the ampacity chart Standard Wire & Cable Co.
