• <div><p>It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between <b>$400 and $2,500</b> to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect <a href="https://www.angi.com/articles/how-to-hook-up-generator-to-house.htm">hook up of a generator to your home</a>. </p></div>

Does installing a generator increase home value?

• <div><p>Yes,<a href="https://www.angi.com/articles/generator-installation-avoid-electrical-disasters.htm"> installing a generator</a> usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts.

Q: What size whole house generator do I need to run central AC?

• <div><p>To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right <a href="https://www.angi.com/articles/whole-house-generator-sizing.htm">generator size</a>. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.</p></div>

Q: Do you need a permit to install a permanent or whole-house generator?

• <div><p>In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between <b>$50 and $250</b>, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you&mdash;and might be required to do so by your building department&mdash;but you&rsquo;ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.</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>
