"Just had them come and install some can lighting in my hall way that I wanted for some time now. They were able to remove my old fixture in the hall and install 4 new LED can lights, even installed the dimmer I wanted with it. Much appreciated!"

"Our house is over 30 years old and the electrical panel was in questionable state after various contractors over the years had accessed it for their projects. For safety and security reasons, we had Rooster Electric upgrade the electrical panel. The electrician needed to cut the house siding to install the new panel and did so expertly, providing new trim and caulking. The job looks great and we feel safer now that the panel is up to specs. Thank you, Rooster Electric, for walking us through the project and doing excellent work. Weâ re so tired of contractors taking the quick and easy route to get their job done rather than providing good, respectable customer service. Youâ ll get our recommendation whenever someone asks if we know a good and trustworthy electrical company. L&N in Fair Oaks"

"JH had to replace our electric box including the necessary grounding under our home to the water pipe, ground arching to the water heater. JH got the county permit, coordinated with SMUD to turn off then on our electricity and get county inspector to pass the work, all expedited. He also kept our necessary appliances running with his generator. I couldn t be more pleased with work."

Generator Install questions, answered by experts

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

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.

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.
