Get matched with top generator install pros in Claremont, CA

Q: How much horsepower do I need?

• <div><p>If your home already has a grinder pump and you&rsquo;re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.</p></div>

Q: Can I use a generator to charge a back-up battery?

• <div><p>Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.</p></div>

Q: 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&rsquo;s natural gas supply are the best option for extended usage, as these won&rsquo;t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won&rsquo;t last as long, as these require fuel storage and regular refueling to stay running.</p></div>

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: 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>

Generator Install questions, answered by experts

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

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.

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’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

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.
