The 75 amp breaker is only for the battery charger (from the WDM). It doesn't limit the output of the APU.....hope this helps!
Yeah, I understand that. I just thought that the limit on the current was relevant to the operation of the electrical system, but it turned out that it wasn't. And there certainly is a limit. Otherwise, short-circuiting the battery would make a heckuva material for youtube.
