Customers say: Quick response

"Dustin, the owner of ECCO Electric, LLC was very friendly and knowledgeable. I hired him to upgrade my 200A service and install a generator interlock/plug. Very detail oriented and shows pride in his work. He ensured the work area was cleaned up after the job was done. He was reasonably priced given how extensive the upgrade ended up being. I d recommend ECCO Electric, LLC for future work."

"I hired Prime Sine Electric LLC for a complete new electrical service and wiring on our 1937 home when purchased. It was in need of a complete gut-job. Spence did an amazing job bringing it up to today's standards. I mean, totally amazing transformation. Spence was professional the entire time through the quote process, customer service and final completion. He listened to our needs and gave input and helped us with planning the electrical needs of this old house. We can't recommend Spence enough and would hire him again in an instant."

Generator Install questions, answered by experts

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

Potential benefits of using a natural gas generator include reducing your carbon footprint, lower likelihood of carbon monoxide exposure, budget-friendly operating costs, and low-maintenance, continuous fuel supply. Some possible drawbacks, though, include higher initial installation costs, dependency on a natural gas supply, and installation complexity. Keep in mind that pros and cons will vary based on the type and brand of natural gas generator. 

In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between $50 and $250, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you—and might be required to do so by your building department—but you’ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.

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.
