"I was pleased with the quality of Cody’s work installing an EV charger. He was very honest. I thought I needed to upgrade my 150 amp service panel to a 200 amp panel to handle the EV charger, but when he evaluated the extra load and the panel’s current load, he told me the upgrade was not needed for the EV charger. That made the job very inexpensive."

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. 

No, you cannot plug a generator directly into a wall outlet in your home. Plugging in a generator without an interlocking kit, extension cord, or wall outlet receptacle is incredibly dangerous and can cause back-feeding—power from the generator back-feeds into utility lines. Also, if the main power comes back on while your generator is on, it could damage the generator and cause a house fire.

Costs range from $500 to $2,500, depending on generator type and installation complexity.

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. 

While natural gas generators are costly, they’re a great option for standby power due to the reliability of natural gas as a fuel source. Unlike other fuels, natural gas is delivered through underground pipes, making outages extremely rare and less likely to be affected by the elements. As long as the area isn’t prone to earthquakes, they offer an unlimited supply of natural gas that doesn’t degrade over time or require storage in tanks.
