"It is weeks like this that make me so happy to have had Fitch Electric install a generator at my house. I had them install an EV Generator a few months ago and bit the bullet for the generator knowing this summer would be HOT and PGE would be shutting us down as usual. I cannot say enough great things about Fitch Electric https://fitchelectricinc.com/ They are professional, reasonably priced and are on-time and on budget. Thanks Lucas and your team at Fitch Electric 5 out of 5 star recommend ! I only said 4.5/5 on the value only because it's expensive regardless so this isnt a knock on Fitch just the whole generator world and PGE in general. I wish we didn't have to do this but in these times over the last several years WE KNOW that PGE will be shutting off power and this is just what we have to do. I love Fitch! Will use them again 100% in the future."

Generator Install FAQs, answered by experts

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. 

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

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.

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.
