Today I built the Polish Generator Transfer Switch. It’s an idiot-proof way of making sure the RV doesn’t get powered by shore power AND the generator at the same time (not good). I knew someone who had an automatic transfer switch fail spectacularly. Not something I want to do. This set up means either the power cord is plugged into shore power OR it is plugged into the generator. Can’t be plugged into both at the same time. When traveling the plug will be removed from the generator and tied up to the SuperStrut the generator is hanging on.
