[ I_z = I_t \times C_a \times C_g \times C_d \times C_i \times C_c ]

Cable sizing is a fundamental aspect of electrical system design. The primary objective is to select a conductor cross-sectional area that is capable of carrying the design current under specific installation conditions without exceeding the thermal limits of the cable insulation. Furthermore, the cable must be robust enough to withstand electromagnetic forces during fault conditions and maintain voltage levels within prescribed limits. bs7671 cable sizing
