"John Gambino was recommended to me on Facebook a year or so ago when I needed an emergency electrician on a holiday. He sent someone out within the hour and the issue was resolved quickly. A few months ago, I again needed some work done and decided to also upgrade to 200 AMP at the same time. John sent out a few guys, including Bill Heaton and Jimmy. The work was done to our 100% satisfaction and Bill carefully explained everything that had been done and why. We recently bought an older home that had knob and tube wiring so we called John once again and he sent Bill out to give us an estimate. I will be honest, we now trust John and Bill so much based on our prior experiences that we didn't even bother to get a second estimate. We knew that the peace of mind that we would have knowing that the job would be done correctly, on time, and by people that we like and trust was worth far more than trying to save a few dollars. Thank you so much John, Bill, and Jimmy. Chuck and I appreciate the work you did so much. Everything looks great and we can't wait to move in at the end of the month! If we ever need electrical work done in the future, you will be the ones we call."

"Carlos is a PRO. Came out installed a new 200 amp electrical panel, conduit protected 200 amp line in, full bonding and grounding system, as well as ran a line and installed a generator interlock kit. He was thorough in showing me how to operate everything, the craftsmanship of his work was next level, everything up and running in a timely manner, and the cost was great. 10/10 would recommend for any and all electrical needs."

"Mr. Rowland installed a light post as well as a century floodlight on the side of my house. He also installed LED energy efficient lights in my basement. The installs were all clean and well done. Not to mention the price was very reasonable. Without a doubt, I would absolutely hire or recommend him for future work."

"The quality of work was poor, some of switches do not work, some of the electric outlet did not work. I contacted the service provider but never heard back from them. The service provider did the bare minimum to complete the job. The quality of the hardware installed is as bad as it can be. It would have been nice if he gave us a few options, showed us what he was going to install but he did not. We got what he chose for us.

He is very professional, explained all options how to get wires from main electric panel to the other side of the house where it would be convenient for us to charge the car. Provided all required materials and get job done fast and safely, made sure everything works properly."

Generator Install FAQs, 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.

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.

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.

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.
