First, find your motor type and OCPD type in Table 430.52. Then, multiply your FLC by the percentage of FLC required by the chart. Using the 53A FLC of our example with an inverse time breaker, you multiply the FLC by 2.5 for a maximum rating of 132.5A. This isn’t a standard OCPD size [240.6 (A)].

WebYou have to oversize an AC Motor to match the torque of a DC Motor. Just because the starter motor is rated at 250W does not mean a 20 amp draw is required at 12V. The current draw is also related to torque. Or how many teeth on the starter vs. the number of teeth on flywheel. Some Li-ion batteries can easily supply 10X their capacity i.e 3000 mAH. WebThe breaker must be sized for 7.6 * 1.25 = 10 Amps. Therefore, it is good practice to size the breaker at 15 Amps. A heater is a device that protects a motor from thermal overloads due to excess current in the windings. According to the NEC, the overload rating must not exceed 115% of the full-load current of the motor.
