[ I = \fracV_dR_cable ]

[ I_req = 84.9 / 0.87 \approx 97.6 \text A ] cable sizing formula

[ V_d = \sqrt3 \times L \times I \times (R_ac \cos\phi + X \sin\phi) ] [ I = \fracV_dR_cable ] [ I_req = 84

[ I_req = \fracI_loadk_t \times k_g \times k_s \times \dots ] Step 3: Select Cable from Tables Choose a cable where ( I_rated \ge I_req ). Step 4: Check Voltage Drop Voltage drop formula (single-phase): [ V_d = 2 \times L \times I \times (R_ac \cos\phi + X \sin\phi) ] cable sizing formula

From table — 25 mm² Cu/PVC (rated ~110 A in air at 30°C). Acceptable.
