"George gave great communication. At the end George and Christian upgraded my panel, installed a sub-panel for my generator, installed an EV charger and prepared my house to change my gas water heater to electric hybrid. His price was fair and he did everything to manage my rebate from SMUD my electric utility company. Highly recommend his work."

"Quick and friendly service. John installed my ceiling fan, fixed a non-working outlet and fixed a light fixture for me. He was ready and willing to take care of whatever problems needed taken care of. One job wasn't even discussed prior to him coming out and he took care of it right away even though it required him to go through the attic to fix it."

"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"

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. 

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.

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.
