Q: How do I know what size generator I need?

• <div><p>When <a href="https://www.angi.com/articles/what-size-generator-do-i-need.htm">choosing the right size generator</a> for your needs, consider a few items to help calculate the wattage you&rsquo;ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:</p><ul><li><p>Refrigerator: 600 watts</p></li><li><p>Large dehumidifier: 700 watts</p></li><li><p>Large window air conditioner: 1,400 watts</p></li><li><p>Water heater: 3,000 watts</p></li></ul><p>Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running. </p></div>

Q: Can you use biofuel in a whole-house generator?

• <div><p>In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.</p></div>

Q: Do I need a permit to install a portable generator?

• <div><p>You may need a permit for a portable generator if you&rsquo;ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.</p></div>

Q: How do generator specifications and installation requirements impact the overall cost?

• <div><p>Costs depend on generator type, labor, and additional wiring or transfer switch requirements.</p></div>

Q: Are generators safe?

• <div><p>When installed and used correctly, generators are safe to use. The <a href="https://www.angi.com/articles/power-out-3-tips-safely-operate-home-generator.htm">most critical generator safety tips</a> to keep in mind are:</p><ul><li><p>Never use a portable generator inside an enclosed space, as the carbon monoxide exhaust it creates is lethal.</p></li><li><p>Never attempt to connect your generator to your home&rsquo;s electrical panel independently; hire a professional for this dangerous job.</p></li><li><p>Never overload your generator by connecting more appliances than for which it&rsquo;s rated; you can damage your generator and appliances or even cause a fire.</p></li></ul><p></p></div>
