"Had Gridwise install a transfer switch and inlet box for our portable generator. We lose power a few times a year during wind events and got tired of running extension cords everywhere. Michael handled the install and walked us through exactly how to connect and start the generator when the power goes out. He was patient with all my questions. Permit was pulled and inspection passed first try."

"Just got a hot tub delivered and needed the electrical run to it. Mark and crew came out and installed a 50-amp GFCI breaker and ran conduit along the side of the house to a disconnect near the tub. Looked way cleaner than I expected. Passed inspection and we were soaking that weekend."

"Very quick to respond, excellent customer service skills, completed the job within a couple days from contact, and provided instructions on how to connect our new generator to the power inlet, and how to engage the system. Jestin is a nice young man trying to grow his new business. I am glad to refer him to anyone I know. Thank you Jestin"

"I had 2 ceiling fan/lights installed in the bedrooms. Installation included 2 new circular circuit boxes in each bedroom ceiling. In addition, I replaced the kitchen ceiling light with an LED fixture. The 2 workers were very polite and professional and worked quickly and efficiently, in addition to being respectful of my personal belongings."

"The consultation with Sean was very helpful and corrected the unit we actually needed. The work was done in a timely way, very professional and thorough. The hook up of the transfer switch was perfect on the trial runs with the generator. Sean has quiet confidence that he communicated with me and gave me the trust I needed to work with his family business that was new to me. I would go right back to Fitzgerald again. Good team, good work, and good service."

"The installers were very sweet and professional. But I donâ t think I was made completely aware of how the exterior installation would look. The last 4 or 5 feet of the white pipeline are not covered and it looks unfinished and messy."

Generator Install FAQs, answered by experts

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

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.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

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. 

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.
