"Mike re-wired my basement outlets at my apartment. He figured out that all of them were wired incorrectly. Not only did he restore power to my basement outlets, he prevented an electrical fire from the previous incorrect wiring. He also installed a new bathroom fan/light combo, with Bluetooth speaker capabilities and multiple led light colors. He was efficient, fairly priced and honest. Highly recommend! Thank you again Mike!"

"The owner Chris was fantastic and answered my calls and questions in record time, came out quickly for an estimate. Once great price was agreed on, he arrived on time with his staff to get started. This is an old house which I'm sure gave them some challenges, but they efficiently went about their business and answered all my questions, got the job done, left everything clean and made sure I was satisfied. Kudos to Will and Aimee! I would highly recommend and will definitely use Calkins Electric again for my next project."

"He is extremely attentive to your needs . What he says will happen , does! He keeps all appointments and thoroughly explains what he plans to do. He is one of the most reliable, ethical , conscience businessman I have ever dealt with. I have recommended him to friends . He actually went out of his way to help Ill friends deal with their generator problems even though he had not installed it. He made arrangements for someone to fix the generator when he was not able. Highly recommended !"

"Kevin has been doing electrical work for us for about a decade, first upgrading the electrical ststem in our 1920s bungalow in Willimantic, and then coming out numerous times to update various elements in our historic home in Chaplin. He's great to work with, no- nonsense, thoughtful about creating safe solutions for our older house, including a generator installation. A nice person and a true professional."

Generator Install questions, answered by experts

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

The average cost to install a home generator is $5,200, but total costs can range from $500 to $18,000 or more. The final price depends on several factors, including the generator's size, type, brand, fuel source, and the cost of labor and assembly. The generator's size is the most significant cost factor, as units that can power larger homes with higher energy demands cost more.

Cost breakdowns by generator type are typically as follows:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500–$2,000

  • Partial-Home Generators (9kW–20kW): $2,000–$6,500

  • Whole-House Generators (22kW–48kW): $5,000–$18,000

To ensure you get the right size unit for your needs without overpaying, consider hiring an electrician to calculate the electrical load of your essential appliances. It is also recommended to get at least three quotes from qualified installers to find the best fit for your budget.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.
