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: Can you switch fuel types for a whole-house generator?

• <div><p>In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.</p></div>

Q: 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&mdash;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: Do I need a permit to install a generator?

• <div><p>In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between <b>$50 and $250</b>, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you&mdash;and might be required to do so by your building department&mdash;but you&rsquo;ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.</p></div>

Q: Is it worth it to install a whole house generator?

• <div><p>A whole house generator can be worth the extra money for peace of mind if your home is prone to power outages for extended periods of time or if you have life-saving medical equipment that needs to maintain power at all times. These devices can also increase your home&rsquo;s value, especially in areas prone to extreme weather and power outages. </p></div>
