Inrush current or input surge current:-
It refers to the maximum, instantaneous input current drawn
by an electrical device when first turned on. For example,
incandescent light bulbs have high inrush currents until
their filaments warm up and their resistance increases.
Alternating current electric motors and transformers may
draw several times their normal full-load current when
first energized, for a few cycles of the input waveform.
Power converters also feature high inrush currents relative
to their steady state currents. This is typically the
charging current of the input capacitance. The selection of
overcurrent protection devices such as fuses and circuit
breakers is made more complicated when high inrush currents
must be tolerated. The overcurrent protection must react
quickly to overload or short circuit but must not interrupt
the circuit when the (usually harmless) inrush current flows
