Here at our house we had a generator bypass switch installed.

Had to have a licensed electrician do it but totally worth it. When power goes out I just turn main breaker off and slide that plate up and hit the generator breaker and boom back in business. There is a weatherproof receptical on side of house for generator. Our currant generator is 8.5 kw. It good enough to run our whole house including the well, but not the hot water and range. My dream is getting a 15-20 Kw diesel generator that will run everything in house and out buildings including workshop area. I really am not willing to pony up dough for it though so stick with what I have for now. For me being cheap is way easier than having all the money to act on all my side adventures.
