Minimum fuse size for short-circuit protection of 3-phase motors. The maximum size is determined by the requirements of the switchgear or overload relay The rated motor currents are for standard 1500 r.p.m. 3-phase enclosed ventilated and totally enclosed fan-cooled motors. D.O.L. starting : maximum starting current 6 x rated motor current.

AC current is calculated by the power factor of 0.86 for single-phase supply and 0.8 for three-phase supply. Look at the table the 1 hp motor takes will be 1.3

Based on Motor Horsepower Motor horsepower and motor Full Load Amperes (FLA) shown are taken from NEC® Tables 430.248 through 430.250 covering standard speed AC motors with normal torque characteristics. Fuse ratings for motors with special characteristics may need to vary from given values. If motor running protection will be provided by the

3 phase motor amps calculation. If we know the watts rating and efficiency of the motor then we can calculate the amperage of the motor or current rating of the motor by using
