Circuit breaker inrush current
WebInrush current is what causes the lights to dim in a house when a motor, such as that on a clothes dryer or vacuum cleaner starts up. Figure 2 (below) is an example of the inrush current for an AC motor. ... It tells us that at 1.5X the rated current the quickest the circuit breaker will trip is forty seconds (1). Forty seconds at 2X the rated ... 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.
