The before picture. We removed the existing 7kw Winco generator and 100amp Eaton transfer switch. The installation area was very cluttered.
We installed a RTSY200A3 200 amp service entrance rated Automatic transfer switch.
We connected the generator to a 1000 gallon propane tank. The generator consumes 2.89 gallons an hour at full load but generally will use half that when lightly loaded. A 1000 gallon tank is larger than most of our installations but a small 120 gallon tank would definitely be too small.
