Get matched with top generator install pros in Chester, CT

Q: What’s the normal lifespan of a diesel generator?

• <div><p>You can expect a diesel generator to last for up to <b>30,000 hours of use</b>, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. </p></div>

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: What size generator do I need for a 2,500-square-foot house?

• <div><p>A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.</p></div>

Q: How can I reduce carbon monoxide emissions from my natural gas generator?

• <div><p>Carbon monoxide emissions aren&rsquo;t only dangerous to human life, but they also harm our planet. While natural gas generators emit lower levels of CO than other fuel sources, there are still ways to reduce emission levels. For example, shop around for an eco-friendly generator that complies with current emission standards. Also, make sure your generator is serviced regularly to avoid CO buildup. </p></div>

Q: Do I need a permit to install a home generator?

• <div><p>Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.</p></div>

"The electrician Kyle was professional , honest and affordable. He was punctual and courteous. I hired him for the wiring and panel upgrade but I requested he change my six GFCI outlets and check the older outlets. He checked the outlets that I was worried about -they were good. He did need to replace a different inside outlet and 2 of the 4 outside outlets. He was kind and explained why they needed to be replaced. One just was no longer working. The other 2 were not up to code actually were a fire hazard. I am female senior citizen grateful I hired Elevate Electric."
