![]() ![]() Wiring a transfer switch panel is not a job for non-licensed electricians. ![]() Please note: Transfer Switch Wiring is NOT for Unlicensed Electricians!! There are at least three good options:ġ) Install a backfeed breaker with a generator interlock switch in your home's main service panel.Ģ) Install simple interlock panel with two double-pole breakers near your home's main service panel.ģ) Install a transfer switch panel to control the critical circuits you need when the utility service feed is down. The answer is to connect the generator to your home's main load center with a manual transfer switch. Who wants to keep a window or door open even a crack when the weather is bad to route-in extension cords running from the generator to the fridge or a few lamps during a blackout? How would you even use a portable generator to power a furnace or boiler, central air conditioning, a sump or well pump, an electric range or any other appliances that are usually wired directly to dedicated circuits? Enter the transfer switch. Portable generators with gasoline engines need to be outdoors and away from open windows and doors when operating. You'd need a more expensive 15,000-watt generator to also power an electric range or central air conditioner.īut by itself, a portable generator is inconvenient to use as an emergency power source. A 7,500-watt portable generator can deliver about 60 amps at 120 volts or 30 amps at 240 volts-enough power to keep a few lights and critical appliances like a refrigerator, well or sump pump working when utility power fails. ![]() The most affordable option is to make do with portable generator. One of the first steps in planning your emergency power strategy is to decide what you need to run during an outage and how much power that will take so you can be sure your generator has ample output capacity. Value Report" suggests why: The average residential emergency backup power system costs about $15,000 to retrofit, and owners can expect to recover less than half that cost on the resale of their homes. While some newer, pricier homes have such backup power systems, few others are so equipped. It would be nice if every home were equipped with a built-in backup generator that had the capacity to power an entire household during a utility blackout and was fitted with an automatic transfer switch to start the flow of electricity from the generator the second after the utility power fails. As power outages triggered by extreme weather events become increasingly prevalent around the U.S., more and more homeowners are exploring options for backup power. ![]()
