Q: What happens with the generator when the local power goes back on?

• <div><p>If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you&rsquo;ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.</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 a portable generator power an entire home?

• <div><p>A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a <a href="https://www.angi.com/articles/installing-whole-house-generator.htm">whole-home generator</a> instead. </p></div>

Q: Do diesel generators have any important downsides?

• <div><p>While diesel is relatively stable, it won&rsquo;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&rsquo;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&rsquo;t always ideal for home use. </p></div>

Q: Is a natural gas generator less expensive than using electricity?

• <div><p>Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It&rsquo;s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator&rsquo;s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.</p></div>

They did a good job just a little disappointed at the way the lock mechanism was installed. I reached out twice to get it replaced and they never called me back. I went ahead and corrected it on my own
