"Outstanding. Prompt, courteous, knowledgeable, reliable, informative and neat. Concerned about functionality and aesthetics of all items installed. Aware of the newest products - in my instance a beautiful Decora type timer and unobtrusive vent cover for a bathroom exhaust. All at a price that is very reasonable."

"I asked for a team to install and wire 8 kitchen can lights. Great professional team that came in on time, did a great job protecting the kitchen, finished the job in less than 2 hours, and cleaned up behind themselves entirely. They charged a very reasonable price, and made the whole project as smooth and seamless as possible. Definitely recommend for your project."

"I contracted with Doug Scholz to replace very outdated switches and ungrounded outlets throughout my apartment. I also asked him to install low voltage boxes and drill holes into the top plates in the walls so I can install ethernet wiring.
On the day of the service, Doug arrived with his colleague Mike and they got to work right away. I had placed the hardware I wanted at each of the outlets and switches. My apartment has old wiring, and they had to troubleshoot a few times. In all, there were roughly 15 outlets replaced (2 prong to 3 prong), 4 dimmer switches installed, and a GFI switch combo installed in the bathroom. Doug also installed 3-way switches for the top and bottom of my stairs. He created access points for me to install ethernet wiring for the apartment at later date. Lastly, he updated my breaker box to remove a double-tap on a breaker switch. Now I have one switch for every circuit.
Doug is extremely knowledgeable and experienced. He had a lot of suggestions and advice. He let me watch and ask tons of questions. Doug knows his stuff! Like I said, the place I have is old, and just by looking at a few outlet boxes and looking into the wall, he could tell the construction history and what some of the more esoteric hardware was.
I will hire Doug again! I wouldn't hesitate to recommend him to anyone else looking for an electrician.

"After a scare by my smoke alarms going off suddenly at night, a 911 call, and visit by local fire dept. who suggested that I have the smoke alarms checked by an electrician; I called K2 Electric. Tom was very professional, and accommodating. He checked the smoke alarms to make sure they were installed properly and installed 2 more while here. He informed me that â newâ alarms arenâ t always in sync with â olderâ models when hard-wired, therefore itâ s best to have all new ones installed. While he was here, I remembered gfi outlet that tripped regularly when in use. Tom replaced that as well. All told it was about 30minutes beginning to end for everything. The price was more than fair for peace of mind- no tax for paying in cash! I have his business card and will use them again in the future if need be. Highly recommended! Thanks Tom."

Generator Install questions, answered by experts

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

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.

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500 to $2,000

  • Partial-Home Generators (9kW–20kW): $2,000 to $6,500

  • Whole-House Generators (22kW–48kW): $5,000 to $18,000

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.

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.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window.
