Q: What size of diesel generator do you need to run a house?

• <div><p>Sizing a generator is a careful process that requires calculating the <a href="https://www.angi.com/articles/electrical-load-calculation.htm">electrical load</a> of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.</p><p>In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that).
