Circuit breaker inrush current

Webhow to calculate inrush current of a motor. Posted on November 6, 2024 by. Formerly with ScienceBlogs.com and the editor of "Run Strong," he has written for Runner's World, Men's Fitness, Competitor, and a variety of other publications. Form wound motors take much longer due to the layers of insulation used between turns. WebInrush current may cause a meter's display to show a value that is higher than the rating of the circuit breaker, yet the breaker does not trip. Why so? Inrush current can be 4 to 10 times greater than the normal running current, depending on the type of motor.
