Residential frig conversion

We have ordered a Samsung 17.5 counter depth refrigerator and will be installing it in 2 weeks. Removing our Dometic propane which is a 2013...(indecently for sale) Our rv is the 2005 38 DS04..Have a quick question , if you dont mind. Has anyone tied in the 110 receptacle behind the frig with the inverter. If so how was it accomplished?

Yes, I did it in the AC distribution panels. Since we never boondock, we don't need the micro on the inverter so I simply swapped the fridge cable with the micro/oven cable. Now the fridge is tied into the small inverter breaker box and the micro is in the larger AC distribution panel.

I just went to a residential and need to switch my micro and refrigerator also. Would you explain a little more of what you did? Did you change your inverter to a pure sine wave also? Thanks, Larry

We just installed a residential refrigerator and had to make the following changes to have the inverter to provide power when in travel status:

1) Our old Magnum inverter was modified sine and only 600 watts, we replaced with a Magnum pure sine 1000 watts. Our refrigerator only pulls 1.9 amps or 240 watts on startup so the 1000 watts was more than enough.
2) Our inverter only provided direct power to the tv area and did not branch off the sub-panel so we could not simply switch the tv circuit with the circuit that supplied the refrigerator 110 outlet. So we needed to run a new line from the inverter to the refrigerator area.
3) In our coach I was able to drill a hole into the plywood supporting the refrigerator which dropped down into the furnace space below the refrigerator. I then pulled the wire behind the cabinets and drilled a hole below the sink that opened into one of our pass-through cargo areas. I then drilled a hole into the bottom of the cargo area which provided access to the bottom of the coach. Finally I ran the wire beneath the coach to my inverter cargo bay and drilled a hole gaining access.
4) I used 10 gauge wire to help with voltage drop since the entire wire length was around 15 feet(probably over kill but I had the wire.
5) I installed a transfer switch behind the refrigerator using the old a/c as the utility and the new wire to the inverter. The transfer output became the new power source for the old refrigerator outlet. This method ended up insuring a/c from shore/generator was primary and inverter secondary.
6) Last step was to install a transfer switch to the inverter area since the small Magnum pure sine wave did not have one. The output from the transfer switch now powers the tv and refrigerator.

My service tech is recommending the micro wave circuit if it is close enough.
