If the load being switched on is inductive, it would be better to switch
the AC waveform at the voltage peaks, not at 0V.  This might seem
counter-intuitive, but it's real.  Switching on at the 0V crossing may
maximize the current pulse through the magnetics.

OTOH, if the origin of the impulse is mechanical in nature, neither remedy
may help.
