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 is a remote start generator?

• <div><p>These advanced generators use a key fob or a smartphone app to remotely start, which is ideal for getting power back on immediately without venturing outside. This feature is more common on whole home generators, but you may be able to find it on large portable generators, too.</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>

Q: Do installations include unit assembly?

• <div><p>Many services include assembling the unit and securing it in the window. Confirm with your provider.</p></div>

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>
