Cable Size Calculation for LT & HT Motors Electrical

Cable Size Calculation of 125 Kw LT Motor. Motor KW = 125. Pf = 0.8, Efficiency = 94%. System Voltage, V1 = 415. Cable length = 200 m. Load Current = P / (1.732 x V x Pf x Eff) —> (P = √3 x Vx I CosΦ = for three phase circuits) = 125000 / (1.732 x 415 x 0.8 x 0.94) ~ 230 A. This is the full load current cable

Motor cable sizing? Electric motors & generators

2001-5-11  Chris33 (Electrical) 26 Apr 01 17:44. When your sizing your cable for a motor you take the FLA of the motor, and in practice I usually multiply this by 1.25. Ex 1: If your motors FLA was 13A, I would then multiply this by 1.25 to get 16.25A. Therefore you would go with a 12 gauge wire because it
