"I had an excellent experience with Tom. He called back with in minutes of my requesting a quote for the job. We made arrangements to meet 2 days later so he could look at what the job entails. He showed up on time discussed exactly what I needed and quoted a very reasonable price. The job was wiring power outlet and cable pass through for a new TV. TV was actually delivered a week earlier then originally planned and Tom was willing to come out the day before delivery so Tv could be installed day of delivery. The work was neat and professional done and I am very happy with the final result. I highly recommend Tom for all your electrical needs, if I could have given him 6 stars I would have."

"With the latest job John and his team completed for us, I am now able to say that for the better part of two decades, the electrical work needs of four generations of my family have been completed by 4th Generation Electric. As John and I were catching up before the install of our transfer switch and generator hook up, he recalled when we first met almost 20 years ago. From that time forward, he and his teams have completed work for my family that spanned from outlet installation and replacement, wiring our full new build construction home, inclusive of aiding with the installation of the power line from the street (which was 700 feet away from the house), outside patio electrical work for an elaborate tiered landscape, generator hook up requirements, among other things. Just as our electrical needs grew over time, and John and 4th Generation Electric have as well, the same level of attention to detail, focus on customer satisfaction, and not only the desire to strive for perfection but the expectation to do so, has been the standard that he knows not only his customers expect but that he expects for himself and his teams. It’s easy to write a review like this when it writes itself. If you have any sort of electrical work needs, big or small, you’d be doing yourself a disservice not asking John for a quote."

Generator Install questions, answered by experts

No, you shouldn’t use an extension cord to plug a generator directly into your home without using a transfer switch. That’s because systems like pumps and HVAC fans need a steady power source that might not be available directly from your generator alone. If you bypass the circuit breaker box, you risk damaging your electrical system, creating a risk of electrical fire or electrical shock to you or any workers repairing lines on your local electrical grid.

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.
