Why Do I Need One?

During a power outage, there are two ways to use a portable generator for power. The first is to run extension cords from the generator to your lights and appliances. However, this is inconvenient and does not allow you to operate some of your critical circuits like the furnace fan or well pump. The second way to use a generator is to connect it directly into your household wiring. Using only one cord, you can now power several or all of your most important household circuits, including the furnace fan and well pump. To do this, the National Electrical Code requires a transfer switch. Direct connection without a transfer switch can result in damage to your home and generator and great harm to utility workers.

How Do Transfer Switches Work?

Transfer switches prevent the utility power and the generator power from powering your household circuits at the same time. When the utility power goes out, you simply plug your generator into the transfer switch, start it up, and flip the transfer switch or switches from the UTILITY position to the GENERATOR position. The most important circuits in your home are now powered by the generator.
