The 2nd 20 amp breaker is only used when I have isolated the shore power from the system to use the inverter. I just wanted to be able to use it during short periods such as staying overnight enroute to another location so I don't have to fire up the generator to support the medical devices and such for the night.
Consider a small $50 transfer switch in the existing branch circuit. This provides automatic isolation. Allows you to use the existing outlets. Can provide backup power automatically if the utility power goes out.
