"We did a major kitchen remodel in our Sharon, MA home. There was a great deal of custom work as we had built in wall oven and induction cooktop installed over the stairwell to our lower level, these appliances required hard wiring and complications in pulling the wiring as we needed 6.2' ft of clearance between stairs and stairwell ceiling where the cookcenter was built. We also had new undercounter lights, under sofit lights and lights installed in new floating shelf. Three new pendant lights were installed, 1 over new island and 2 over new dining area. Bchara also fixed some electrical wiring problems we were experiencing over the past 9 years. He was prompt, professional and came in at a very reasonable cost. He was also responsible for recommending the excellent general contractor we hired for the entire remodel. Our kitchen turned our beautifully thanks for the superior electrical work done by Bchara . We give him 5+ stars!"

"Russell did an outstanding job. He went to our house, saw what had to be done, explained everything, and his fee was more than fair. He did an annual maintenance on our generator (and ordered a spare key for it), installed an electrical outlet (while having to cut away wall & work around studs & water pipes), replaced light switches, disconnected an old intercom system, removed a circuit from breaker box. He will be the professional I call, if I need an electrician. Totally recommend."

Generator Install FAQs, answered by experts

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

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. 

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.
