in rush current is the current that surges into the circuit as soon as it is switched on due to the capacitance of the circuit.... if surge current is too large it can cause damage to the wire and capacitances it uses.... and also electromigration...
Is correct, if you think you have a problem, you may want to consider a FET with a cap, to create a soft start circuit. Calculate the value of the cap to determine the rise time of the circuit. Typically industry uses this type of circuit to avoid inrush current, which may cause damage to your input circuit.
