Rather than polluting MS's fine "optimal switches" thread http://forums.sailboatowners.com/index.php?threads/1-both-2-off-switches-thoughts-musings.137615/
here's my separate one for discussion of variations, whether speculative but sound, or noobie ignorance remains to be seen, all feedback welcome.
> The three switch configuration has little to do with "combining banks" it is all about isolation, redundancy and the ability to "cross-connect" either bank to power and start the entire boat in an emergency
>If you want the three-switch configuration wire it properly with three switches.

my modified Three ON/OFF Switch configuration
http://i.imgur.com/tJQcamJ.jpg
The Blue Seas Dual Circuit Plus' OFF disconnects BOTH batteries from their respective Load circuits, so in normal usage the lower 0/1 switches stay ON, only the top DCP switch gets turned on and off.
Each bank can be independently isolated if needed, either one can feed either House panel or crank/engine circuits.
Note the Alt directly attached to Primary (house) "always on buss"
Smart VR sensors on both batteries and Alt temp.
Sorry for the crude sketches & handwriting, all I got's my phone ATM.
Question: combiner/echo unit should be below the switch, not above it, correct? (if so, see next diagram for correction)
