When you use a 50A to 30A or even 15/20A the converter cord takes the single power input (30A, 20A or 15A) and connects it to BOTH 50A feeds into the coach. As you probably know, a 50A circuit in the case of our coaches is actually two 50A circuits whereas 30A and below are only one. You may well have to change the maximum power input selection on your inverter/chargers. I would also recommend turning one of them off if you have a single battery bank, which is likely. Don't turn off the breaker feeding that inverter/charger ONLY turn off the charger. This is necessary so that the 110VAC input to the charger/inverter still flows through the inverter bypass relay to power whatever is attached to the leg of power in your coach.

The one thing that may not work is the cooktop. Our cooktop is 220VAC so it can't be powered with a single power feed.
