I just thought I would chime in. I purchased a "cheap" Sportsman 3200W generator with RV connector to use in very limited circumstances with our new 30A trailer. When I hooked it up everything worked great but when I tried to use my Progressive Industries PT-30C it would not trip on. I now use a 15A male plug with the ground and neutral connected, as per PI, plugged in to one of the outlets on the face of the genny to bond the neutral and ground. I also run a 3' grounding rod off of the ground lug on the face of the genny. I want to run my PT30C with the generator because it is a cheap generator and if it decides to go bonkers I will be protected. When it is time to use the generator for running electrical tools on the property I just unplug the bonding plug and all is good. Read your generator instructions on why bonding is not a good idea when running electrical hand tools.
