Size Calculation - How To Cable

During a short circuit, the cable must survive intense heat before the protective device trips. Verify the minimum cross-sectional area ( ) using the adiabatic equation:

[ I = \fracPV \times \textPower Factor ] (Power factor ~0.8–1.0 for motors, 1.0 for resistive loads like heaters) how to cable size calculation

[ I_tab \geq \fracI_loadC_t \times C_g \times C_i ] During a short circuit, the cable must survive
