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: 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: How much energy can I expect a home wind turbine to generate?

• <div><p>Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home&rsquo;s needs. Accurate output estimates require a professional wind assessment and a review of your household&rsquo;s energy usage patterns.</p></div>

Q: What size generator do I need for my house?

• <div><p><a href="https://www.angi.com/articles/what-size-generator-do-i-need.htm">Generator size requirements</a> vary wildly among properties, but typical generator sizes are listed below based on home square footage:</p><ul><li><p>1,000 sq ft: 6&ndash;9 kW</p></li><li><p>1,500 sq ft: 7&ndash;10 kW</p></li><li><p>2,000 sq ft: 10&ndash;14kW</p></li><li><p>2,500 sq ft: 12&ndash;16kW</p></li><li><p>3,000 sq ft: 16&ndash;20kW+</p></li></ul><p>Unfortunately, home square footage isn&rsquo;t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you&rsquo;d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.</p></div>

Q: Is a natural gas generator less expensive than using electricity?

• <div><p>Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It&rsquo;s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator&rsquo;s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.</p></div>
