We just installed a Reliance Protran manual transfer switch. It is all of 6 circuits and only uses 120 volts. It is rated for up to 7000 watts. We use our Honda eu3000i to power the switch. We have two bedrooms, kitchen, heating system, and office/freezer running off the circuits. The particular items powered are Dish tv system, freezer, refrigerator, security system, heating system, lights, computer system, kitchen wall plugs. We also have two small window AC units we can install as needed. We don't run every thing a once. The transfer switch has two meters that indicate wattage being used. The generator has a 3 gallon tank and it lasts about 20-24 hours.
