Powering my home from my MH during an outage

You don't have time for tomorrow, but I'd wire this with a transfer switch and simply not have the 240 volt items connected to the transfer switch. Until then I'd just shut off the breakers on 240 volt circuits. Probably nothing bad would happen if you tried to run them, but I wouldn't risk it.

Yes, only my Oven uses 240v. I had forgotten the dryer was gas too. And we rarely use the electric oven, like 3 or 4 times a year. We live in San Diego so A/C almost never gets used, although climate change seems to be changing that scenario. -Bill

I don't believe in taking too much stock in advice from an open forum for matters like this. Opinions are usually worth what you pay for them.

All the hard stuff was already done by the professionals. (per the OP) I am just making a cord from my Inverter to the previously installed generator connect inlet. I am using the diagram that Magnum provides for my inverter as it is meant for such an installation as documented in the manual. -Bill

I included a 30 amp two pole breaker dedicated to a generator feed AND the the main breaker lockout which only allows a "this or that" configuration to prevent back feeding into the local grid. (See attached image) My portable generator is 7500 watts single phase which allow just about everything in the house that is 120VAC but not the 240VDC items. If I need to power the house I trip the main, slide the lockout to clear the generator breaker, close the generator breaker and also trip the four two pole breakers. Safe and easy on the house side.

For the coach the simplest way to feed power safely is add a NEMA 14-50R receptacle somewhere in the coach that is easy to access with a power cord. This is the same outlet type you plug into at a camp site. Then use a correctly sized power cord with a matching twist lock plug to the house receptacle on one end of the cord and a NEMA 14-50P on the other end so you can safety feed the coach to the house with no exposed conductors.

The only question is to where to connect in the coach. At the output from the generator? Transfer switch? Breaker panel? Inverter output? Hard to say but I really don't like to double up a power feed so if possible I would consider adding a two pole breaker to the main panel, if possible, and feed the receptacle from there. When not in use leave the breaker off and the receptacle deenergized.

I have a similar situation except my local utility provider installed my new 200 amp panel when they were under-grounding our service a few years ago. I had an electrician install the 30 amp generator breaker just below the 200 amp main then install the lockout apparatus and a generator inlet port.

I decided to use my Inverter to supply the house power as A. It's certified for that type of install, it can use my 8kw of batteries to supply the power, they are also being charged by 1500w of solar. And I can still use the generator if necessary to charge the batteries if/when needed. Magnum had the exact wiring diagram in the manual to provide power to both sides of the house breaker panels buss. Attaching it to the 120v genny had no documentation I could find, so the Magnum made the most sense. -Bill
