While you can of course plug in a conventional gasoline-powered generator, I use this transfer switch to plug in a 12 volt power inverter during power outages. The inverter generates 120 volts from my car battery. If you get a big enough one (maybe 1000 watts) it will sustain the brief initial "transient" surge of power needed to get an electric motor going. The actual power needed after than initial surge is pretty low: about 300 watts. It is probably best to run the car's engine while doing this, so as to be sure to have full power and to prevent the car battery from running down. This method worked on my old furnace with a cheap power inverter. On my new furnace (a fancy one with electronic controls) there was a twist: I found I had to use a "Pure Sine Wave" inverter, not a standard (so called "modified sine wave", which is closer to a square wave) one, to make it start. (a refrigerator and sump pump don't need pure sine wave).
With a power inverter one can avoid the hassle, expense, smell, gasoline-storage hazard, and pollution of a gasoline generator that one almost never needs to use.
The instructions for this transfer switch assume you will be connecting this switch to your main fuse box. But I found that it's more convenient to connect it on the line leading to your furnace--a method shown in illustration on the box but not detailed in the instructions. Use great care to be sure to wire it up correctly.
To use this connector you use a heavy gauge orange extension cord. Plug it into your generator. Plug the other female end on to the reverse plug on the Reliance. By moving the switch from line to generator you change the electrical input to your furnace. The switch simply bypasses the circuit from the house. There is a no power position as well.A red light showing generator power input. And a 15amp built in circuit breaker.
I have added a more robust transfer switch over the years which covers 8 of my circuits (see other review). I moved this unit to my swimming pool for those times when summer storms knock us off line. Also, you can place this unit directly on your furnace at the junction box coming in --takes a little more thinking--or as my neighbour did-- moved it to his garage and ran wiring out to it.. again these installs require bit more electrical knowledge.
By comparison, the year before we were left without power during the October snowstorm ("Snowtober"). We did not have this device and relied on our generator and a small space heater to heat our living room. The space heater guzzled the gas in the generator and BARELY created enough heat in the room to be noticeable. We were miserable.
With the gas crisis that we experienced after Hurricane Sandy, the Reliance Control switch was a miracle. It hardly used any gasoline to power the thermostat and ignite the natural gas burner that heats the house (through radiators). We had friends staying with us because we had heat and felt guilty for those that were left cold (some of our friends house temperatures dipped into the 40s after a week - but we were toasty in our house, which was in the 70s).
I cannot recommend this device enough. I suggested it to everyone I know after the storm. It is a must have if you experience power outages during cold seasons. The switch is easily powered by a small generator and only requires a regular extension cord that runs from the generator to the switch (you don't need a special cord - just a regular 3 prong extension cord (2 prongs + 1 ground).
Based on my experience and the comfort it brought to my family and friends, I would have paid double for it.
