How many days can a standby generator run continuously?

• <div><p>The <a href="https://www.angi.com/articles/how-long-can-whole-house-generator-run-continuously.htm">amount of time a standby generator can run continuously</a> is around <b>3,000 hours</b> 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.</p></div>

Can I plug my generator directly into my house?

• <div><p>No, you cannot plug a generator directly into a wall outlet in your home. Plugging in a generator without an interlocking kit, extension cord, or wall outlet receptacle is incredibly dangerous and can cause back-feeding—power from the generator back-feeds into utility lines. Also, if the main power comes back on while your generator is on, it could damage the generator and cause a house fire.</p></div>

Q: What size generator does my house need?

• <div><p>You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. </p><p>A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you&rsquo;ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.</p></div>

Q: Can you run a whole-house generator constantly?

• <div><p>Yes, whole-house generators run constantly for extended periods. Whole-house generators can run for longer periods of time than portable generators, but be careful. First, they may need regular applications of engine oil (as frequently as daily), depending on the engine design. Second, running constantly for several days will increase the wear and tear on the generator and shorten its lifespan.</p></div>

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>
