You might be wondering why you need to purchase a transfer switch. A transfer switch lets your generator power the most vital hard-wired appliances such as your well pump, septic pump, and furnace with your generator. While some generators come with a transfer switch, not all do, and especially if you have well water or a septic tank an automatic transfer switch is one-hundred percent necessary to get the most out of your generator.Installation is not a "do-it-yourself" project; you should have a licensed electrician install it for you.
