"They were running a little late but they let me know and kept in communication. They were quiet because I worked from home. The prices were fair and my dogs loved them. I was just very pleased with the overall work."

Small jobs welcome

"C.J. was very professional, very skilled and did an excellent job installing two heavy chandeliers - one to replace an old one and one to be moved to center over the kitchen table. I was amazed at how he went about his job; he was very precise and very careful to get the job done right and to our satisfaction. I was also very impressed with this young man who not only did a great job but did it all my himself, prepped the site and cleaned it after the work was done. I would recommend him for any electrical job. Theresa A."

"I cannot stress enough how impressed I am with their commitment to customers. After the installation of an outlet for an EV charger and an upgrade to my panel, I had a minor issue. Within an hour of me reaching out to inform them of the issue, I received a call with an offer from Endrite to come by later in the day to take a look. The repair was done at my convenience with no additional charge. They were thorough and went beyond what was probably needed to ensure the problem did not re occur."

Generator Install questions, answered by experts

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. 

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.

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.

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.
