Q: Can a 10,000-watt generator run a central AC unit?

• <div><p>A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.</p></div>

Q: What size generator do I need for my house?

• <div><p><a href="https://www.angi.com/articles/what-size-generator-do-i-need.htm">Generator size requirements</a> vary wildly among properties, but typical generator sizes are listed below based on home square footage:</p><ul><li><p>1,000 sq ft: 6&ndash;9 kW</p></li><li><p>1,500 sq ft: 7&ndash;10 kW</p></li><li><p>2,000 sq ft: 10&ndash;14kW</p></li><li><p>2,500 sq ft: 12&ndash;16kW</p></li><li><p>3,000 sq ft: 16&ndash;20kW+</p></li></ul><p>Unfortunately, home square footage isn&rsquo;t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you&rsquo;d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.</p></div>

Q: What’s the normal lifespan of a diesel generator?

• <div><p>You can expect a diesel generator to last for up to <b>30,000 hours of use</b>, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. </p></div>

Q: Are natural gas generators worth it?

• <div><p>While natural gas generators are costly, they&rsquo;re a great option for standby power due to the reliability of natural gas as a fuel source. Unlike other fuels, natural gas is delivered through underground pipes, making outages extremely rare and less likely to be affected by the elements. As long as the area isn&rsquo;t prone to earthquakes, they offer an unlimited supply of natural gas that doesn&rsquo;t degrade over time or require storage in tanks.</p></div>

Q: Do you have to turn off the main breaker when using a generator?

• <div><p>As a safety measure, you should always turn off the main breaker while operating your generator&rsquo;s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.</p></div>
