Mike,
I'll wait for the Bob's definitive answer but this makes no
sense. That would be like adding a 100 am panel to your home and feeding
it off a 20 amp breaker in your main panel.
The lead from the main power bus to the endurance bus should be
a direct feed from the same terminal as the main feed. Between them is a
diode to prevent backflow if the e-bus alternate is used.
Also, I have an issue with the orphaned switch for fuel pump #2.
Why not integrate it with the engine primary and secondary switching?
Note that if fuel pump #1 makes trouble, this diagram provides no way to
isolate it, but rather one method to switch the bus that feeds it. With
switch #2 I can turn it off/on at will which is fine as a backup, but I
want that functionality for #1 also.

I agree, it seems wrong. Which means I've probably missed something fundamental with the design/diagram. Hopefully Bob will weigh in and shed some light. His explanations routinely make things clearer.
