I just did an install on my 5th wheel,I dont have a drawing of how i did it but will try my best to explaine, I wanted to power all my outlets, I have 3 breakers i wanted to run off of inverter two run the tv's and the rest to charge phones cameras etc etc.. I tested all breakers to find the circuits for the outlets, I ran a 10/2 cable with a 30 amp breaker to one of the inputs on the automatic trans switch,then ran a 12/2 from the inverter to the other input on the trans switch,then the output on switch to a sub-panel that feeds all four breakers on it to all outlets. this way when my inverter is running and i turn on gen it will automaticly transfer over to gen, and when the gen or shore power goes off it turnes over to inverter so i always have 110v on my outlets. sorry if i confused any of you guy's.
