Inrush current is the initial surge of current that flows when an electrical device is first turned on.
Inrush current occurs due to the charging of capacitive loads and magnetization of inductive loads.
Inrush current can cause voltage drops, tripping of circuit breakers, and damage to electrical components.
Inrush current can be reduced by using soft-start circuits, pre-charging capacitors, and selecting appropriate fus...
