Q: What can I run on different generator sizes?

• <div><p>Here&rsquo;s what you can run with different wattages and types of generators:</p><p>Portable generator:</p><ul><li><p>2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. </p></li><li><p>4,000 watts will keep two large appliances operating and a few smaller devices.</p></li><li><p>8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.</p></li></ul><p>Partial to whole-house generator:</p><ul><li><p>20,000 watts and above will make it seem like your home&rsquo;s power is still on.</p></li></ul><p></p></div>

Q: How long can a whole-house generator run continuously?

• <div><p>Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.</p></div>

Q: How close can a transfer switch be to a generator?

• <div><p>Generally, you&rsquo;ll want to keep between <b>60 and 70 feet</b> between the generator and the transfer switch. There are a few reasons for this, including:</p><ul><li><p>The distance reduces the noise coming from the generator into your home.</p></li><li><p>It increases efficiency because you won&rsquo;t have a voltage drop from this short of a distance.</p></li><li><p>Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. </p></li></ul><p></p></div>

Q: Is a home generator a tax write-off?

• <div><p>Most homeowners won't be able to claim a home generator as a tax write-off. However, a whole-house generator may be tax-deductible in certain situations depending on its purpose. For instance, if it's needed to power essential medical equipment, it may qualify as a medical expense deduction. Also, in some cases, businesses can deduct a generator as a business expense if it supports operations. Always consult a tax professional to determine eligibility based on your specific circumstances and the applicable IRS regulations.</p></div>

Q: What are the benefits of a portable generator?

• <div><p>Portable generators provide backup power for essential appliances during outages and are easy to relocate.</p></div>

Generator Install questions, answered by experts

Here’s what you can run with different wattages and types of generators:

Portable generator:

2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers.
4,000 watts will keep two large appliances operating and a few smaller devices.
8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

20,000 watts and above will make it seem like your home’s power is still on.

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

The distance reduces the noise coming from the generator into your home.
It increases efficiency because you won’t have a voltage drop from this short of a distance.
Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window.

Most homeowners won't be able to claim a home generator as a tax write-off. However, a whole-house generator may be tax-deductible in certain situations depending on its purpose. For instance, if it's needed to power essential medical equipment, it may qualify as a medical expense deduction. Also, in some cases, businesses can deduct a generator as a business expense if it supports operations. Always consult a tax professional to determine eligibility based on your specific circumstances and the applicable IRS regulations.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.
