Hello Listeners,
I just wonder if that email was missed.
It's a dual alternator single battery triple feed essential bus setup
for my IFR RV-10.
So far I got one person (thanks John) comments but would appreciate any
further comment.
Thanks a lot
Werner

Dear all,
here my 1st attempt, the load analysis is mostly based on manufacturer loads yet and I did not yet fill all the columns. Distribution is based on the mission IFR, however it has more on the essential bus then needed, due to the limitation of 20 slots on the main fuse board.
I have a different approach for the Aux alternator as I had already the SB1B controller, so by standard the Aux alternator would be switched on together with the main alternator.
one thing I'm not 100% certain if the Aux alternator switch/bus-sense is on the right bus, as I would need to have the alternate feed switch on in case I would switch of the main bus or the Aux alternator would shut down (maybe the bat bus is the right location?)
Thanks for review an comments/questions.
Cheers Werner

If you're following the Z101 that you attached, the aux alternator
controller should be on the Essential Bus and the bus control should be
as drawn.
On the issue of load distribution across buses, you can extend a 'bus'
by simply adding another fuse block and tying the input posts together.
If 20 isn't enough, just add another 6, or 10, or 12, or whatever slots
with another block and tie their inputs together.
Hope that's helpful,
Charlie

Thanks Charlie,
I thought about adding but then, is there a drawback to have a tad more
(about 4) on the essential (as I have aux generator) so the battery only
operation is a very very low probability and I still could switch a few
things off manualy if needed.

As long as the aux generator can 'tote the load', then it shouldn't be
an issue. But if it can't, I'd probably think twice before loading up
the essential bus that much, for simple human factors reasons. Stress
would be higher from losing the primary alt, so adding to the work load
to remember to load shed sounds like a less than good idea. 
Something else to consider is that I've never had a homebuilt that
survived 1st configuration (meaning as-bought, for me) for very long,
and I'm pretty sure that there are things I'll change on my
project-RV7's wiring that's 'complete'. When you fly for 6 months and
realize that there's one more electrical gadget you'd like to add, from
where will it get power?
I like 'spares'. I've got a spare (used) microwave stashed in the
hangar, to pull out for temporary use if the built-in in the house dies
(and it's been used that way). Spare tools in various locations in the
hangar and in the walk-in area under the house. I have backups for so
many things, my spouse says she thinks I probably have a spare wife
stashed under the house for when she's gone.
So... I have spare slots in my fuse blocks in the current flying RV6
(which I rewired) and the RV7 project.

Thanks Charlie,
I will reconsider and thinking about 2 10 blockes at the position of the
20 block. the aux should, from the calculation, be more then ok to keep
the current essential load but again I will reconsider the split 
one question about the alternate feed, battery and main contactor are in
the tail behind baggage bulkhead, do I consider right to have the
alternate feed relay at the same place so the hot wire between Battery
and Relay is as short as possible?
Thanks for the feedback
Werner

Charlie here Revision B,
aux Load on Essential down to 20A, 5 SPare slots on Main Bus, 2 on
Essential, a bit to redo and order another Busmann block for Bat bus.
