"Forrest is a professional all the way. I would trust and hire him for any job he can do, and maybe some he cannot. Honestly decent from the heart and concerned about his clients. He took time to guide me through a hands-on start-up of the generator he installed. Forrest made sure to clean the area he worked in and was extremely polite."

"Electrician provided excellent service, told me what he was going to do, listen to Meyer concern regarding the location of the outlet, and cleaned up upon completion of the work. Afterwards he demonstrated how the placement of the outlet allowed me to reach my EV without any issue."

"I hired Ben to install a generator plug and a few misc electrical duties. He was very professional, timely, and the work is unmatched. During one of the electrical outlet installs he brought parts of my home up to code which I greatly appreciate. He talked me through the different options on what he recommended and I trusted his judgment-luckily everything worked out perfectly. I highly recommend this young man and itâ s always nice hiring small American business."

Generator Install FAQs, answered by experts

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

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.

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.

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.
