"I'm very satisfied with his work. I had used him for 16 years and I had him install two different generators. I never had any problems at all and he is very responsive; that is why I have recommended him before."

"Paul did a great job of explaining what the problem was and the options available for addressing the problem. His recommendation for a solution was actually the least costly option. Paul presented as extremely knowlegable, professional and courteous. I was surprised at how quickly the installation was completed. The whole experience from the first contact with the company through the installation exceeded expectations."

"Fabian (the electrician) was an absolute professional. I let him know what I needed and he provided me with several options on how to get the task completed within code. He provided me with a specific timetable, which was great for me because it allowed me to work around my work schedule. Once the job was finished, it was as if he was never there. Everything was cleaned up and put back the way it was when he initially arrived. Highly, highly recommended!!!"

Generator Install FAQs, answered by experts

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.

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.

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.

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.

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.
