In snow storms scenario a generator is a very good idea. Per my understanding 15KW to 17KW would be enough for a home of 1600 sq foot. A generation with the above specifications can easily serve the desired purpose.
A=lw A=20*80 A=1600 feet2
A 22-27 kW home standby generator would generally be suitable for a 4500 square foot house. However, factors like energy usage, appliances, and climate can impact the recommended size, so a professional assessment is recommended for accuracy.
Impossible to say without knowing how many rooms and what size they are.
by foot
Yes, an 8kVA generator can run a small house. A generator this size should be able to adequately power a one ton air conditioner, 18 cubic foot refrigerator, and other small appliances normally found in a small house.
Carriages, horses, and by foot.
A foot is a unit of length. A square foot is a unit of area. The two units are therefore incompatible.
There are 304.8 millimetres in one foot. Therefore, rounded to two decimal places, 1600 millimetres is equal to 1600/304.8 = 5.25 feet.
1600 sq ft = 1600/9 sq yd = 177 7/9 sq yd. Almost 178 square yards are needed if all floors are to be carpeted. If it is a two floor house, additional carpeting may be needed for the stair risers, but usually the kitchen and bathroom(s) are not carpeted so their areas may be subtracted.
A 25 foot cord will not cause enough voltage drop to worry about.
a 4 ton unit
There are 3 feet in one yard. Therefore, 1600 feet is equal to 1600/3 = 533.3 recurring (that is, 533.3333..) yards or 533 yards 1 foot.
