"Review by BILL K in Dubuque. Projects: installed bathroom fan, heater & light. Rewired the junction box in the detached garage to restore the use of the overhead double door. Knowledgeable, professional, prompt. I recommend this contractor very highly. Will call on him again should the need arise."

"I first asked for a quote back in February of 2024. When I received the quote I decided to wait on this project. Then we lost power for 2 days due to a storm. I then decided it was time and contacted the contractor again. He sent me an updated quote and the project was scheduled. It's now installed and I'm very happy with how it turned out. Hopefully it will be a long time before we need to use the generator because we lose our power. But we are ready when it happens. I will definitely use this company again for any electrical jobs that come up. Andrew and his crew were great."

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. 

Many services include assembling the unit and securing it in the window. Confirm with your provider.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

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.

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.
