"I cannot recommend RYB Electric LLC and Sebastian highly enough! We hired them for several electrical upgrades, including: 1. A full electrical panel upgrade 2, Installation of a Level 2 EV charger, and 3. Installation of ground rods for extra protection Beyond his technical expertise, Sebastian is a pleasure to work with. He is incredibly easy to talk to, has a great personality, and took the time to answer all my questions without making things feel overly complicated. It’s rare to find someone who is both a master of their craft and so personable. The workmanship is top-tier—everything is neatly installed, labeled, and functioning perfectly. If you are looking for a reliable, skilled, and fairly priced electrician who truly cares about the quality of his work, look no further than Sebastian. We couldn't be happier!"

"Scott is very experienced and he knew what to do with an electrical problem that I had. Opposed to other electricians, Scott knew exactly what was wrong. He did a good job and I am especially impressed with his honesty. Scott didn't use scare tactics or try to talk me into other unneeded electrical work."

"I have used Pipe Works on numerous occasions as of this date and find them to provide excellent service at competitive prices. Their associates are great to work with and their prices are competitive. The work is always completed on time, as promised and the work area is left clean. I appreciate that they point out things that need repair in the not so distant future. It was great to wake up the other day with power coming from my new Kohler Generator"

Generator Install questions, answered by experts

While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.

In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between $50 and $250, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you—and might be required to do so by your building department—but you’ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.

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.

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.
