* I doubt your
portable generator could handle all that,huh? I'm talking bare bones/ no frills
110/220 voltage output( ,,,er,,, refrigerator?,,,copy
If you want a whole house generator to take care of the basics like furnace fan, lights, microwave and refrigerator then you are looking at around a 7500 watt generator; because you want one that can handle all of them running at the same time.
Problem with both refrigerators and furnace fans is that the initial surge is a lot higher then the steady pull and THAT is what you have to have the capacity for.
Now a/c is even more of a juice hog especially at start up; you need at least 18 amps at 120 volts which is 2160 watts JUST for that; now once its running it will go down to around 12 amps (depending on its size) which is 1440 watts.
you have to calculate all of that for each item you want to run on the generator and always add 10% just in case.
