Q: How big of a generator do I need for a transfer switch?

• <div><p>You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator&rsquo;s largest outlet is 30 amps, you&rsquo;ll need a 30-amp transfer switch.</p></div>

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: 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>

Q: What can I run on different generator sizes?

• <div><p>Here&rsquo;s what you can run with different wattages and types of generators:</p><p>Portable generator:</p><ul><li><p>2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. </p></li><li><p>4,000 watts will keep two large appliances operating and a few smaller devices.</p></li><li><p>8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.</p></li></ul><p>Partial to whole-house generator:</p><ul><li><p>20,000 watts and above will make it seem like your home&rsquo;s power is still on.</p></li></ul><p></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>
