Electrical Wiring in the Home/RV generator to house hookup


Hello Bob;
  My question involves using the 4000 watt Onan generator that is installed on my RV to supply me with power for some household essentials during a power outage.
  Would I be able to plug in a heavy duty 20 foot long double male power cord from an outside RV receptacle to an outside house receptacle, that is on a 20 amp breaker, and then flip off the house main and other un-necessary breakers except the ones controlling a refrigerator, two heater circulators, (baseboard, 1/25 HP .71 amps;  and hot water, .74 amps), an electric range top, (just one element at a time) and 3 or 4 low wattage light bulbs?
  If this too simplistic or a dangerous solution, what would be the safe and correct way to go about getting the power into my home from the generator?
  Thanks for any response.

You should not do it that way.  You risk a fire, shock, ruining the generator, and even shocking a utility worker.

The only safe way is to use a generator transfer switch.  This would require having a sub panel.  The only other way is to use things that you can plug into the generator.

Sorry to be the bearer of bad news.
