Did I Just Fry My Appliances?
This past weekend I took my dad's 5th wheel to a buddy's farm to hang out for a couple of days. Both of our generators were at our farm a couple hours in the other direction. So, i ran down to the loc...

Yes, a 30 to 50 adapter ties L1 and L2 together at the shore power cord so that the two hot busses of the 50 amp RV's power distribution center (breaker box) behave like the single hot bus of a 30 amp RV. Maximum current is limited, however, by the 30 amp shore power breaker in the pedestal, so the overloaded neutral scenario cannot occur.
The power management system on our RV defaults to 30 amp service when the voltage between L1 and L2 is 0VAC and sheds loads accordingly - for instance, the 2nd A/C compressor is blocked out on 30 amp service when the convection microwave is enabled. The power protection system, however (the EMS-PT50C, which we also have), shows the current draw from each bus in the RV's power distribution center regardless whether the supply service is 50A or 30A. With the hot busses tied together by the 30 to 50 adapter, both busses will show the same voltage.
The power management system and the power protection system are two completely different systems with different functions.
