A transfer switch will cost you about $1000 installed, maybe more, but then you can hook up your generator to your whole house if you have a 240VAC generator. I am looking into a genny like this, most likely going to have to get a 5500-7500W unit to get the 240VAC that I need.
There are other options, if I were to build a new rural home I would get a propane backup Generac generator installed on building, but then again I may also build off grid and not worry about their blackouts.
