Inverter Hard Wire install
We'll be bringing home our first Fifth Wheel in a couple days, and I have all the components for a 4-battery bank (Trojan T-105's), Magnum MS2812 inverter, inverter remote, and Trimetric TM-2030-RV mo...

Do not leave the power cord to the RV "hot" when running the inverter.
Use a transfer switch that is active when on shore power.
OR (and this is what I do)
Place a shore power outlet powered by the inverter in the shore power cord box. When you disconnect from the campground, just plug in the inverter, set the fridge to gas, and disconnect the converter.
Since the Magnum has a superior charger, I leave my converter off at all times. My RV behaves as if it were on shore power while I trundle down the road or when I'm boondocking.
Doing this with plugs has the advantage of being able to eliminate the Magnum from the circuit. You may find that many GFCI outlets do NOT play well with the Magnum. It could be quite frustrating to have shore power that can not be used.
Shore power cord-->female plug-->male plug-->feed for Magnum-->feed to female plug in shore power cord box-->feed to power distribution center.
If GFCI gets in my face, I simply plug the power distribution feed plug into the outlet powered by the shore power cord which eliminates the Magnum from the circuit. Then I plug in the OEM converter and I'm back to "stock" wiring.
Since I have a portable generator this makes it very easy to power the RV from the genny.
For the DC side of the Magnum, use the recommended size of wire for the "run".
I do have one dedicated inverter outlet that I use in the kitchen. This lets me use an induction cooker and the toaster or waffle iron at the same time. It also allows me to use the Magnum for additional power, provided that I turn off the OEM converter, on those occasions when GFCI rears it's ugly head.
