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). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. </p></div>

Q: Can I plug my generator directly into my house?

• <div><p>No, you cannot plug a generator directly into a wall outlet in your home. Plugging in a generator without an interlocking kit, extension cord, or wall outlet receptacle is incredibly dangerous and can cause back-feeding&mdash;power from the generator back-feeds into utility lines. Also, if the main power comes back on while your generator is on, it could damage the generator and cause a house fire.</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 diesel generators have any important downsides?

• <div><p>While diesel is relatively stable, it won&rsquo;t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it&rsquo;s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn&rsquo;t always ideal for home use. </p></div>

Q: How much does it cost to install a generator?

• <div><p>The typical <a href="https://www.angi.com/articles/how-much-does-it-cost-install-generator.htm">cost of a home generator</a> is around <b>$5,000</b>, but prices range from <b>$400 up to $13,000</b>, depending on a few factors. The most significant cost factor is the generator size, as larger generators that can support more square footage usually cost more. You can install an emergency backup generator for between <b>$500 and $2,000</b> or a partial-home generator for between <b>$2,000 and $6,500</b>. Whole-home generators usually total between <b>$5,000 and $13,000</b>, with some models climbing as high as <b>$18,000</b>.</p></div>
