Keep the power flowing with a 50-amp RV Box Adapter
Two 30-amp plugs on a heavy-duty 17-inch cord supply power to the 50-amp receptacle, and can receive power from any combination of 30, 20 or 15-amp sources. The ideal setup for this device is one 30-amp connection paired with another of either 20 or 15-amps. Using this adapter means you'll never be without power, regardless of where you set up your RV, and you will be free to operate your lights and appliances as they are needed.
The adapter has a built-in mechanism that prevents short circuiting, as well. If there is too much power coming from one source, the device will actually draw additional power needed from the second generator to compensate.
