Average electric power used in a house

[Guest]

Hello,
want to get a natural gas electric generator for my 3 bedroom home. What KW (volts, watts, amps)size generator should I be looking for ?

Here's the Kohler calculator - there are probably others, too.

depends, just add up the hourly consumption in watts for everything you use, add a few hundred watts
