Hi Jay,
Thanks for the reasoning behind the way you have to do it on a BB...
I was not thinking in terms of the 50 amps... I do see what you mean...

I too, had my boat wired that way. My boat had 1 air conditioner.

The boats total draw with everything running would not exceed 50
amps total. So, with 2 3o amp legs, the 50 amp load could be divided
even enough to keep the loads down to the maximum 30 amps per leg.

With the Bird, we have 2 legs of 50 amps. You COULD make a mistake
and have 2 or 3 a/c's ON and, for some reason, loose shore power
(city power glitch, someone trips on your cord, you accidenatlly
swith the matster changeover switch, etc).

The internal, 30 amp MAXIMUM, transfer switch would try to transfer
the 50 amp loads. 2 things would happen- 1.) the internal transfer
switch would probably cook 2.) you would instantly overload the
Inverter, which will try to sustain the load up to about 40 amp
draw, then it will shut down. You would have had a 12V draw of about
375 amps which should be sufficent to blow the 300 amp fuse that is
in the lines that connect the inverter to the batteries.

Too much crap to go wrong when its wired so that ALL the loads COULD
pass thru the Inverter.

Note that on the $1M rigs, they use 2 inverters with 50amp internal
switches each.

Bottom line- Install it correctly and there will be no booboo's ;~}

you know I do not have a BB yet... But , I do have a boat with a
Heart 2500 Inv, Chgr, a 200 amp ample power alternator, link 2000R
and 6 T 105's with a 12 volt starting batt... I purchased my 2500
before Xantrec bought out Heart...

to add a generator, solor panels or wind generator...
