WebOct 8, 2024 · Based on the graphs, a formula to calculate current carrying capacity is given below: I = K ΔT0.44A0.75. K = 0.024 for internal conductors and 0.048 for external conductors. ΔT = Maximum temperature difference in °C. A = Cross-sectional area of copper trace in mil². WebThe short circuit capacity of the cables is calculated according to AS/NZS 3008-2024 as. Where: I is the short circuit current capacity in amperes, t is the short circuit duration in seconds. S is the cross-sectional area of the conductor. K is a constant that is selected from Table 52 in AS/NZS 3008-2024.
WebWith its exceptional current carrying capacity, copper is more efficient than any other electrical conductor Because of its superior conductivity, annealed copper is the international standard to which all other electrical conductors are compared .
