"Nick Murray, one of the Murray brothers, replaced a circuit breakers panel in the basement and installed a full house generator with switch panel on my house. Nick did a great job! Very professional and courteous. I would definitely recommend this company for electric works."

"Needed a 240V outlet installed, Eddie gave a great quote and got the job done fast. Went the extra mile and gave us a heads up for making sure we got the right type of drying machine to match the outlet interface. Great communication in setting up the job, showed up on time, really personable fellow. Would definitely use their services again and recommend to a friend. 5/5."

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. 

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.

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.

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

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.
