Speaking from experience--hurricanes can teach you a lot-- consider a few things before you invest. It's a luxury to own an automatic generator--but your prime interest is FUEL ! I have struggled thru quite a few hurricanes--one for 26 days and the last for 16 days without power. One of my neighbor's companies had a complete automated system(12kw) installed since he worked out of his house. Only trouble he was out of LP gas on the third day and there was no way a delivery truck was available for 12 days! Of course once the power goes "OFF" you don't know how long it's gonna remain "OFF"? So you must conserve! The average household just consumes like they are still being supplied by the power company....
Being an electrician you can improvize --- now i was on a well, but had LP gas for cooking and water heating. My neighbors planned for nothing !!! I had a 7kw portable unit that i wired into my house at 240 volts. I was very critical to what that generator fed, not because of electrical load, but because of fuel consumption. I ran a single circuit to each of my neighbor's houses to feed their refrigerator/freezers. I also cross connected my water system with their houses to provide them water. They did not have gas so they could use my showers for warm water as needed. The generator was started every morning at 7:00am and ran until 11:00PM. I disconnected all my appliances at the breakers to prevent them from being damaged by poor power from the generator. I disconnected all the TV sets and used an old black and white portable for news broadcasts. Gasoline for the first week was hard to find--got up one morning and drove over 100 miles to find gas and then it's rationed like 10 gallon max! After a week, gas was not a problem--i was burning about ten gallons a day and the neighbors were bringing their share. Consider the fuel source when considering a permenent system.
