You really have to cover your ass when installing a generator to run the house. First thing is a three way switch so you don't back feed the grid with electricity. You shock a lineman and folks will come looking for you, and they'll know it's you because youre the only dude with lights and a/c on the grid. I know a very good electrician that can get you lined out, and he's a gun guy too! Pm me if you want his info.
