"Richard was on time and took the time to go over everything and let me know up front how much it was going to cost. He also was super informative and also let me know about the other services that he offers and was even able to give me a couple of rough estimates on other projects that we are interested in having done. Which was very much appreciated. The job we hired him for to clean our gutters and downspouts was done perfectly and so quickly. He was even able to check a spot on our roof near the chimney that we were concerned about leaking. He was able to recalk it for us while he was up there. Highly recommend Richard with Spellman Home Services. We will defiantly hire him for future projects!!"

"Rough Diamond Construction Company did an excellent job remodeling my family room/basement. Nate's attention to detail and his expertise was well worth every dollar paid. He was always in contact with me as well as advocating for me when I had a water problem in my basement with the company who initially made the repair. Because of the water problem I experienced in the summer, I decided to have the entire room renovated - new floors, walls, ceiling, doors, etc. Nate and his crew were professional and efficient. The end result is that the room is absolutely beautiful. I would recommend Nate and his team to anyone - you won't be sorry."

Generator Install questions, answered by experts

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

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.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

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.
