"Superb experience! Greg provided an education along with the estimate and each team that has come out to place the generator, wire the generator, and complete the install (after the propane gas hook up) has been terrific -- professional, courteous, wearing masks per CDC and Virginia guidelines. The installation, (generator, transfer switch, panel and status lights) are all finished to a T and look great, too!"

"The project was extremely challenging. The hidden wiring under the floor would not budge, so the new wiring had to be routed a new way. Daniel did a great job figuring out how to do it so it looked good. Nice! They even worked during a tropical storm, in a houseboat. We discovered there were no GFI's at the last minute, and they installed them immediately. Throughout the project, Daniel understood the complex schematics instantly, and was not flustered as obstacles kept popping up. He re-wired the new panel like he had been doing those same boat panels every day! Great attitude and work ethic and professionalism."

"The pros at Intrinsic Electrical have been my go to electricians for years. They’ve upgraded my electrical panel, installed light fixtures, replaced receptacles (outlets), installed switches, and, most recently, completed all the electrical work needed for my bathroom remodel. Not only do I recommend them, I recommend not wasting your time considering anyone else."

"These people are fantastic! Brandie answered the phone right away and took my information. I told her I needed the job done quickly and she sent my name and number to Jay (electrician), who luckily happened to be working near my area. He called me back promptly and although he had several other jobs, made arrangements to do the work for me the same day! He arrived at the time he said he would be there, and did a fantastic job! He patiently readjusted the height of the large chandelier several times until I was sure it was right, installed the large fixture flawlessly, cleaned up afterwards, and charged me a reasonable price. This company will be my "Go-To" for any electrical work from now on."

Generator Install questions, answered by experts

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.

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.

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.

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.
