Adjusting what circuits are powered by inverter?
I am not sure how to look at the electrical panel and figure out how to change what circuits are powered by the inverter or if that is even the place where they are wired in?
We are going to ditch the Norcold and use a residential refrigerator and i need to change the location of power supply to refrigerator outlet.
I know which outlets have the power, I just don't know how to change it.

I assume you're talking about the 110 volts.
On mine there was an outlet in the frig compartment that my absorbsion frig (Dometic) was plugged into to supply 110 volts. Plugging in your residential frig into this outlet should be acceptable, but I wanted to also be able run my frig off of an inverter.
The circuit that feed the frig outlet also feed several other outlets (Microwave, counter tops, etc. I wanted my new residential frig to have its own breaker that was also feed by an inverter that I was going to install..
I added two circuit breakers in my existing panel, one to supply power to my auto changeover pure sine wave inverter and the other was to supply a new outlet for my 12 volt converter. It was also sharing a circuit and I wanted to put it on its own breaker.
My PSW inverter detects if it loses 110 volts and switches automatically back and forth, either inverter power or regular 110.
I also added switches on a panel so I can select almost all the MHs 110 volt circuits to get 110 volts from either the inverter or the regular shore power.
I wrote this up with photos and diagrams
Pure Sine Wave inverter install – 1999 Southwind 35S
I also did a short writeup for my residential frig changeout.

...not to offend anyone, but if you are not comfortable with this sort of thing--get a professional to help you....IRV2 is a great place for advice on a lot of things but rewiring 120v circuits is not one of them.....IMHO

waiter21 - You mentioned that your frig draws about 0.7 amps when running. Do you know how much it draws when in defrost mode, and does the inverter handle that well? My Whirlpool also uses less than an amp when running, but kicks up over 3 amps (360W+) in defrost, which the PSW should handle well - unless it spikes at first.

Adjusting what circuits are powered by inverter?
Having been an industrial control designer, I am comfortable making electrical changes. My microwave and refrigerator wiring is all in the back of the refrigerator location. I was able to install a double pole, double throw switch to be able to route inverter to the refrigerator or microwave. The other is then powered via shore power or generator. The refrigerator is the position that I leave the switch. Only when traveling stopped at lunch, I select the microwave to be on the inverter to heat a quick lunch.

The concept of what to do is simple. Move the wire to socket to an inverted circuit. The problem is the implementation as I have seen several different ways to distribute the power with one or two panels for inverted and non inverted power. That makes the answer installation specific. The best most of us can say is to either learn how your unit is wired, add another wire and socket, or hire someone who understands how to make it happen.

I do plan to hire someone, I just wanted to know how it's done. I am not doing it. I just wanted to know if it's as simple as moving a wire from inverter power to the correct breaker is all. My hopes were he can just do that and eliminate the power from locations I don't care about, as I would also like to power the outlets by the bed for CPAP. (Then if I do stop overnight w/o shore power I still can sleep and run the refrigerator for 5-6 hours) Right now they are not, it's all focused toward the entertainment stuff which we don't use. I am always plugged into shore power except when on the move, hence the power needed to run the refrigerator. Thanks for all the replies.

If you had an ice maker in the old refer there may already be wiring in place and just plugging in to where the icemaker was plugged in may cure your problem.

OK;
There should be Two Electrical Boxes. Normally they are next to each other.
One for Inverter.
One for Shore Power.
Each one should have its own set of Breakers.
Wires will come from one or the other - you will have to be disconnected to work on - both shore and Battery - before you disconnect from power - You need to ID the circuits - each and every one, every outlet will be on a circuit - every light will be on a circuit - Note here some will be 12 volt not on the 120 shore or inverter these are not connected to either but the battery and are 12v fused.
Pull off the covers to each box and disconnect from Shore Power and Battery Inverter - check to be sure you are power free.
I D the circuits you want to change then if you have enough slack in the line swap to where you want them, if not a junction box and new wires will be needed. (Electrician will understand)
Check to be sure they are properly wired to fused wire size - 15 amp 14 gauge (Usually white) - 20 amp 12 gauge (Usually Yellow) - Swap and re-I D the circuits.
Check everything to be sure its tight - reconnect to Shore power and Inverter - check to be sure everything works you should be done.
That's as simple as I can explain it - really not that hard - will save you a lot of Time and Money if you do all the I D work first.
Hope this helps,
edit - If you will only use this when traveling it just might be easier to just fire up the Generator - it will just be running at idle and might cost $5.00 a trip - likely cost you $150 - $250 for the Electrician. A lot of trips to get to ROI.
KISS

Unless you have a PSW (pure-sine-wave) inverter, your CPAP machine will likely not play well with the regular MSW inverter. Same for the newer electronic electric blankets, etc.

Good Point - think this is his inverter - https://www.solar-electric.com/xantr...SABEgLW1fD_BwE
He might need to check to see if it works with his equipment.
