"Jeff and his team did an amazing job for my home renovation. They rewired an entire floor, removing then installing all new outlets, wiring for mini-splits, televisions, fixtures, fire/co2 detectors and a new electrical panel. They installed three wall mounted televisions, numerous lighting and fan fixtures with ease. Josh was a beast, crawling around in the attic and getting our new bathroom vents in and making sure all the switches worked together. They put in some late hours to make sure the job was done right. I would highly recommend Jeff and his team for your electrical needs."

"I have to say that David Krafton is an excellent electrician. I. Called him about a. light. Over. My sink that I could not fix by replacing the bulbs. He came out and told. Me the light was not working, as it was shorted out. He then went and bought me a new light and installed it. It works get and is so much brighter the the previous one. Thank you David I will be calling you again to do other work for me. Loraine in Bedford N.H."

Generator Install questions, answered by experts

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.

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

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

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.

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.
