Use Motorhome Generator as Back-Up for Sticks & Bricks Home in Electrical Posted May 26, 2021 · Report reply You can buy kits for a manual disconnect that will install in your house breaker panel and will lock out generator power from utility power. I would get an electrician to do the work if you are not skilled to do the work safely. Typically with a portable generator this work is routinely done. He will install a new 240 volt breaker and wire in a 50 amp outlet on the house. Then you would need a 50 amp cord to the RV but again you would have to install a 50 amp outlet on the RV from the generator. A Safety disconnect is a must!
