"Highly recommend FUSE Electric! Nate showed up on time, was easy to communicate with, and did a great job. Everything was done professionally and the pricing was very fair. FUSE Electric may be a newer company, but Nate has been doing electrical work for decades and it definitely shows. It was a great experience all around and we’ll definitely call him again for any future electrical work."

"We needed a bath fan/light installed to replace a bath fan only, which also meant adding a switch; plus outside and inside outlets. Levi was great to work with! He was here when scheduled. His attention to detail and cleanup went above and beyond. Levi was respectful, friendly, and even wore foot covering inside our home. He would tell me when the tools would be loud. We would highly recommend Freedom Electric, and should we need electrical work completed… would definitely reach out to Levi! We wish him the very best in his business!!"

"Sean does a great job. He has helped me on numerous projects, including installing outlets and switches, programming smart Lutron switches, installing ceiling fans, installing 12 and 24 volt tape lighting, installing outdoor outlets in my yard, etc. He is very knowledgeable, works efficiently, has reasonable prices, and is honest and fair. As a solo electrician, his charges are far less than what you would expect from a larger company. I could not recommend an electrician more highly than Sean."

Generator Install FAQs, answered by experts

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.

Many services include assembling the unit and securing it in the window. Confirm with your provider.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

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. 

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.
