"Creekside Power is outstanding for electrical work!! The attention to detail put into their work when installing my Generac home standby generator was first class. I am pretty OCD about the way things are done, and Shawn s work was definitely up to my standards. I would highly recommend Creekside Power their price was my second lowest out of 14 estimates... Shawn was only $125 higher than my lowest estimate... and that person was not trained & certified to install Generac products, nor was he a Generac dealer like Shawn... that made my decision very easy. Everything was completed in a neat and orderly fashion. Shawn was very patient throughout, taking the time to answer my frequent questions. He used a level throughout the install and took his time as a result, everything lines up and matches up with my existing breaker box, etc. Shawn was very careful, diligent, and a bit OCD about how straight everything was during our install, which I thought was great!! Shawn takes pride in his work and it shows! Call Shawn for a free estimate... Shawn knows his stuff and you will like him. He did a great job for us on two jobs - a backup/standby generator install and a replacement of my meter channel!! He also ran a new electrical line to an out-building at my mom's house. I have already recommended Shawn to anyone I know who mentions wanting to get a generator installed."

Generator Install questions, answered by experts

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.

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.

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.

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.
