Note: I initially posted the wrong diagrams. See post 22 for current configuration as of 29 Apr 23.
I know what is causing the issue...I just don't understand why. What's going on (power flow)? My hope is that one of the "real" electricians here can explain so my thick skull can comprehend.
I made up a 30A dogbone today with a SmartPlug female end so I'd have a spare cord with me. Every time the EMS contactor in the camper engaged the shore breaker blew with the new cord.
The problem IS NOT too much power drawn by the RV or a mis-wired dogbone.
Below is the wiring when the breaker blows. What I think is happening is the 120V shore power is being applied simultaneously on the Multiplus' input and output. (Trace the wiring and you'll see what I mean.)
-DIAGRAM REMOVED-
With the manual switch set to NOT 50A the Multiplus' output is isolated from the input power. This config works perfectly.

I couldn't find anything specific on the Victron Community site and my googlefi failed me searching for a clue. Obviously having shore power on the input and output of the Multiplus is no bueno...I just don't understand why the shore breaker popped (except for the obvious that too much current was drawn...but why?)
For the curious, below is the standard 50A configuration.
