Q: How close can a transfer switch be to a generator?

• <div><p>Generally, you&rsquo;ll want to keep between <b>60 and 70 feet</b> between the generator and the transfer switch. There are a few reasons for this, including:</p><ul><li><p>The distance reduces the noise coming from the generator into your home.</p></li><li><p>It increases efficiency because you won&rsquo;t have a voltage drop from this short of a distance.</p></li><li><p>Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. </p></li></ul><p></p></div>

Q: What happens if my whole-house generator is too small for my AC?

• <div><p>An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home&rsquo;s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.</p></div>

Q: Can a portable generator power an entire home?

• <div><p>A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a <a href="https://www.angi.com/articles/installing-whole-house-generator.htm">whole-home generator</a> instead. </p></div>

Q: Is it better to repair or replace a malfunctioning generator?

• <div><p>It&rsquo;s usually better to repair your generator if it isn&rsquo;t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around <b>$300</b> on average, while <a href="https://www.angi.com/articles/how-much-does-it-cost-install-generator.htm">installing a new whole-house generator costs</a> around <b>$5,000 </b>on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.</p></div>

Q: Do I really need a generator transfer switch?

• <div><p>Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for <a href="https://www.angi.com/articles/what-is-an-electrical-emergency.htm">electrical emergencies</a>. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. </p></div>
