"We wanted a highly rated electrician to do the work installing a generator and a hot tub at our house. We hired Jared and were very happy with his work. The quality of his work is unmatched. Everything is very neat & labeled nicely. He was respectful of our home and quick to respond. We would highly recommend Jared."

"I hired Matt when I was in the process of converting from a natural gas wall oven and cooktop to electrical versions. There had to be a lot of rewiring done, and he and his men did a great job. They arrived promptly at the agreed time to do the preliminary work and then arranged to come at the same time as the appliance installers to finish the job. Matt even took the time to fix my doorbell for me when I mentioned that it had not worked for years :-) It was clear that they are incredibly competent and the job went very smoothly. I would definitely hire them again if I need electrical work done in the future. Thanks Matt!!"

"Jason and his team with Cotti-Johnson did an excellent job updating our electrical boxes, installing the washer/dryer hookup, and getting us setup with a generator! Sam, our assigned electrician, even took the time to go through the entire operation of the generator from A-Z. I would definitely recommend them for any electrical work!"

"I hired Chris to upgrade an electrical panel. The price was very fair. I was going schedule some work on two small jobs, he decided to have a quick look at them while here and realized it it was a very quick fix, so he took care of them in short order at no charge. He's old school, for the younger people out there it implies he's reliable , honest, and fair priciing, and more importantly he will be the only electrician i will hire for my electrical needs. He'll be coming back to install a generator and some small jobs. Can't recommend him high enough. Tony Chaves,Taunton"

"Expensive but professional. The electrician that did the work was excellent and seemed.to enjoy explaining what he was doing and why it had to be done that way. I felt like I learned something while he installed ceiling lights. He also cleaned up after himself like he'd never been there."

Generator Install questions, answered by experts

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.

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

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.

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.
