Inrush current can be 4 to 10 times greater than the normal running current, depending on the type of motor. So if a motor's running current is eight amperes and its circuit breaker is rated for 20 amperes, how is it possible that a clamp meter could display a measurement of 40 amps?

By definition, inrush current is greater than the normal operating current of the equipment, and the ratio can vary from a few percent up to many times the operating current. A circuit that normally draws 1A from the mains may easily draw 50 to 100 times that when power is applied, depen...
Inrush current is the maximum current drawn by an electrical circuit at the time it’s turned ON. It appears for the few cycles of input waveform. The value of the inrush current is much higher than the steady-state current of the circuit and this high c

In particular, the ability to control the inrush current into AC powered supplies at > 1 kW is a key application of these niche devices. We will review why and how this is such a beneficial technique for the power supply engineer, especially for the latest in bridgeless PFC topologies. We...
While consuming less efficiency motors are much more likely to trip their respective circuit protectors when they start Initial start-up current-or inrush current-is the culprit. This current can be several times greater than the operating or steady state current of the motor. In a 3-phase ...
