"Justin did great job, intalled the hookup and the transfer switch for the portable generator. Worked in freezing temperature outside. The only downside was that the install was postponed few times because he was waiting for the parts"

"Preferred Electric came right out to provide me with an estimate, which was lower than others and he seemed professional, so I hired him. He was able to perform the work within 2 weeks. He came and did the work himself. He installed the bath fan and kitchen curciuts as requestd. I then had him come back to install the smoke and CO2 Alarms in the house."

Generator Install questions, answered by experts

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 $50 and $250, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you—and might be required to do so by your building department—but you’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.

As a safety measure, you should always turn off the main breaker while operating your generator’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.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

You can expect a diesel generator to last for up to 30,000 hours of use, 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. 

While natural gas generators are costly, they’re a great option for standby power due to the reliability of natural gas as a fuel source. Unlike other fuels, natural gas is delivered through underground pipes, making outages extremely rare and less likely to be affected by the elements. As long as the area isn’t prone to earthquakes, they offer an unlimited supply of natural gas that doesn’t degrade over time or require storage in tanks.
