"Jarod did an excellent job. Completed an EV outlet install in a few hours. He came out to do an estimate and had all the supplies he needed in his truck and hired him on the spot. Fair pricing and very neat a clean work. EV outlet works like a charm. Will definitely hire him to do future work at my house."

"I highly recommend Elite Electrical! I had them install four outdoor receptacles around my house, and the entire experience was flawless. From start to finish, he was incredibly professional, timely, and got the job done surprisingly fast without cutting any corners. What I appreciated most was how courteous he was—he took the time to keep me informed and explained every step of the process so I knew exactly what to expect. The workmanship is clean, neat, and works perfectly. If you need any electrical work done right, Elite Electrical is the way to go!"

"These guys did a fantastic job: they were organized and punctual, offered a great product, and provided education on how to use the generator. They even installed an extra conduit without my requesting that they do so in case in the future additional wiring might be required under the driveway, Nick is a real professional and Amber in the office keeps the ship sailing!!"

"Atlas gave me a quote for the work I required. They were spot on. We needed a new circuit added for a replacement gas range. The electrician showed up on time and was able to complete the installation in under an hour. We talked with them about additional electrical work we will need done. We will hire again."

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. 

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

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.

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.

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.
