I have a fair understanding of wiring AC systems. And I have a good understanding of 12 volt systems. But I'm lost doing systems on at trailer. The part that I'm lost on is. Ok I wire my TTT for AC to run my coffee maker, it plugs into the wall socket. Now I also have a 12volt battery with an inverter. Will I be able to wire the 12v power to the same wall socket to run my coffee maker ?
Or do I have to power the top part of the socket with AC---and the bottom part of the socket with the inverter 12v DC power (then move the electric cord plug to the proper socket position?)
Or do I have to make a master 3way switch position 1 DC/ position 2 OFF/ position 3 inverter 12DC.
Yeah I'm lost
