Avionics power ratings are always available as nominal and max normal
draw.  Electrical systems are designed with a bit of extra capacity to
deal with power on rush current, etc.

The only time an aircraft author would have to give the the current draw
any thought at all is if they're also building special avionics and even
then, they only really need to specify the nominal draw.  The only time
the breakers will pop is either on command from an instructor station or
via a random systems failure routine.
