Size the switch so that the Class J, time-delay fuses are used at a minimum of 150% of motor full load amps or next size up (for light starting duty applications, Column A). For general applications, excluding wound rotor and DC motors, NEC® 430-52 allows sizing at 175% of motor full load amps or the next standard size per NEC 240-6 (Column B). If sizing at 175% will not allow the motor to start, NEC 430-52 will allow the fuses to be sized up to 225% of motor full load amps or the next size down (Column C). Note: In sizing the fuses, the motor FLA, is per Table 430-150, not per nameplate information. Inrush currents of motors may vary, consult motor manufacturer data for correct sizing. On elevator applications, motor load plus auxiliary loads need to be considered. Follow elevator manufacturer’s recommendation for correct fuse sizing. For estimation purposes only, Column C can be used as a conservative approximation.
