Fair pricing and very neat a clean work. EV outlet works like a charm. Will definitely hire him to do future work at my house."

"Exceptional from the start! Scott responded in less than 24 hours after I requested a quote and was able to stop by and evaluate my project. His rates were more affordable than competitors. He communicated thoroughly, was highly professional, and his attention to detail was more than expected. He showed up on schedule and got the project done in a timely manner. I don’t know what more I could say, but I highly recommend. I will be using Scott for all future electrical work!"

"Josh and his crew did a fantastic job! They changed out the circuit breaker box. This included having to expand and upgrade the area so the new circuit breaker would fit. After the new circuit breaker was in, he came back another day to ensure the wall around the circuit breaker was professionally repaired. In addition to this job, they also installed a stackable washer and dryer in the main bathroom. It was a very tight fit and he had to enlarge the area to make it work. In the end, both jobs were done in a professional and timely manner. The customer service was prompt and exceptional. We would hire them again without any hesitation."

Generator Install questions, answered by experts

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.

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. 

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.

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.

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.
