Q: Do I need a permit to install a 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: How long can a whole house generator run?

• <div><p>As long as they have enough fuel, whole-house generators can run for weeks at a time (400 to 500 hours) without suffering too much wear and tear. However, this type of extensive use isn&rsquo;t ideal if you want to extend the life of your generator.</p><p>Two important points. First, some generators may need you to periodically check oil levels every day or so and refill as necessary for safe operation. Second, if your generator uses a fuel tank, keep it regularly full so it doesn&rsquo;t suddenly shut off. Many backup generators can run through a full tank in a day when they are powering large portions of a home.</p></div>

Q: What are the disadvantages of a standby generator?

• <div><p>While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.</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: What’s the lifespan of a natural gas generator?

• <div><p>When properly maintained, natural gas generators can last a long time, as much as <b>20 to 40 years</b>. They have relatively few needs compared to generators with other fuel types. However, the generator&rsquo;s lifespan ultimately depends on how often the generator is used and for how long it&rsquo;s left running.</p></div>
