"This is the 2nd time I have used Safe Electric and both times I have used them have been great experiences. I had 3 new fixtures installed plus a new circuit run to be used for a new freezer in our finished basement. Jon & Eric were the two electricians that were sent to my home. They worked efficiently and quickly, but did outstanding work. Even though our basement had a finished ceiling, they were able to run a wire through with minimal disruption to the finished ceiling. I had concerns about the alignment of the lights on the fixture (this was a manufacturing defect and nothing to do with their installation) and they obliged me by improving the light alignment. They also cleaned up after they were completed and disposed of the old light fixtures and packaging materials for the new fixtures. Their work was excellent. The only negative aspect was the price which seemed very high to me. The cost for installation of the 3 light fixtures was $462 and the new circuit was $903."

"I hired KAP for several projects from installing a whole house generator, house rewiring to installing light fixtures. Either a large or small job they were professional. I highly recommend them for any electrical work."

"Scheduling with Breeze was super simple and they were able to accommodate my busy schedule. My technician was polite and was able to trouble shoot errors that a previous electrician made. I wish I had used them to begin with. The Generator was Installed in one afternoon too! As for pricing I thought they were average. You get what you pay for though, they do quality work so I donâ t mind paying a little more. Less headaches in the long run!!!"

Generator Install questions, answered by experts

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.

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.

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

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.

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.
