What occurs if inrush current is not managed properly?

When inrush current is not managed properly, circuit overload can occur due to the sudden surge of electrical current that happens when electronic devices or motors are turned on. This initial surge often exceeds the normal operating current and can be several times the rated current of the device. If the inrush current is not limited, it can lead to overheating of components, tripping of circuit breakers, blowing of fuses, or even damage to the electrical equipment itself as it struggles to handle the excess current.

By ensuring proper management of inrush current, such as through the use of soft starters, current limiters, or inrush current limiting devices, the risk of circuit overload is significantly reduced. This not only protects the equipment but also maintains system integrity and efficiency. In contrast, the other options, such as increased efficiency, lower operating temperatures, and extended device lifespan, are not directly associated with the mismanagement of inrush current and typically represent the positive outcomes of effective current management strategies.
