Inverter install help

Plugging the shore power cord into the inverter outlet is foolproof and back feeding is not possible since the shore power cord can only be plugged into one thing at a time. The only critical thing to disable is the converter. The other high draw items I mentioned flipping breakers off for are a "just in case they get switched on" precaution because they would overload the inverter. Installing an additional breaker in your AC panel to isolate the converter to may be the only additional modification necessary to use your inverter in this manner to run all the outlets, and it might not even be necessary if your converter is already isolated or on a breaker you can turn off that leaves your outlets still hot.

If you expect to swap between shore power/generator and inverter frequently during a camping trip, or if you want the inverter powering things while you're traveling, then the convenience of installing a slick transfer switch does seem attractive.
