Customers say: True professional

"Travis came to look at the problem on a Tuesday morning. When I explained to him that lights in the house were flickering he became concerned and put my job on the top of his list. Once he arrived he immediately diagnosed the problem as many of the circuits in the box had deteriorated due to moisture in the line. He fixed the bad circuit in question and showed me the problem and explained that due to the age, oxidation, and rust that I may have future issues with the remaining circuits. I decided to replace the entire circuit panel and circuits as well as have a new meter with new wiring and drip lines installed on the exterior of the house, as the old meter was also corroded and detaching from the siding.. Travis returned early the following day at the exact hour we had agreed upon and worked a full eight hours to complete the entire job. His work is exemplary: very neat and methodical and whenever I had a question he would answer it in detail. His work was completed within the 2 days and came to approximately 10 hours in total. He supplied all the necessary materials and had everything he needed on hand in his truck.. I recommend him very highly as a skilled and experienced electrician located in Berkshire County."

"Dave, was professional and reliable. He did the job very well and returned when we had questions and resolved them. We upgraded our service from 100 to 200 amp electrical service. We also installed a charging port for our new electric car. We are very satisfied with the new service and charge station. I would highly recommend him to others."

Generator Install FAQs, answered by experts

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more.
