Q: How many days can a standby generator run continuously?

• <div><p>The <a href="https://www.angi.com/articles/how-long-can-whole-house-generator-run-continuously.htm">amount of time a standby generator can run continuously</a> is around <b>3,000 hours</b> on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home&rsquo;s natural gas supply are the best option for extended usage, as these won&rsquo;t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won&rsquo;t last as long, as these require fuel storage and regular refueling to stay running.</p></div>

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

• <div><p>No, you shouldn&rsquo;t use an extension cord to plug a generator directly into your home without using a transfer switch. That&rsquo;s because systems like pumps and HVAC fans need a steady power source that might not be available directly from your generator alone. If you bypass the circuit breaker box, you risk damaging your electrical system, creating a risk of <a href="https://www.angi.com/articles/how-to-put-out-electrical-fire.htm">electrical fire</a> or electrical shock to you or any workers repairing lines on your local electrical grid.</p></div>

Q: What types of fuel do generators take?

• <div><p>Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:</p><ul><li><p>Natural gas: $2,000&ndash;$21,000 per year </p></li><li><p>Liquid propane: $2,000&ndash;$21,000 per year</p></li><li><p>Diesel: $3,000&ndash;$20,000 per year</p></li><li><p>Gasoline: $500&ndash;$3,000 per year</p></li><li><p>Solar generator: $2,000&ndash;$25,000 per unit</p></li><li><p>Battery backup: $10,000&ndash;$25,000 per unit</p></li></ul><p></p></div>

Q: Where can you install a whole-house generator?

• <div><p>Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.</p></div>

Q: How do I know what size of whole house generator to choose?

• <div><p>Generators are usually sized by running watts and starting watts. Ideally, you&rsquo;ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. <a href="https://www.angi.com/articles/electrical-load-calculation.htm">Calculate your home&rsquo;s electrical load</a> based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.</p></div>

Guess I got lucky. Hired Jeremiah to weld a theft proof box on my RV trailer for my 4000 watt Firman generator. Couldn't be happier with his expertise and quality/design. I highly recommend him for just about any weld job. Exceeded my expectations.
