Q: What size of diesel generator do you need to run a house?

• <div><p>Sizing a generator is a careful process that requires calculating the <a href="https://www.angi.com/articles/electrical-load-calculation.htm">electrical load</a> of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.</p><p>In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. </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: What incentives or rebates are available for home wind turbine installation?

• <div><p>Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.</p></div>

Q: How do I reduce AC startup power for a generator?

• <div><p>To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.</p></div>

Q: Can I plug my generator directly into my house?

• <div><p>No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause &quot;back-feeding,&quot; where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.</p></div>

He installed a chandelier, light switch, and neon sign above my fireplace. He also rerouted wires in my guest bathroom and installed a vanity light. He also added three outlets in the house. Great work all around. I would definitely recommend him for anyone that needs electric work done."
